An HSA (health savings account) or FSA (flexible spending account) can pay for a prescription GLP-1 medicine, such as Zepbound (tirzepatide) or Wegovy (semaglutide), when the weight loss is treatment for a specific disease a physician has diagnosed, for example obesity, diabetes, hypertension or heart disease. It can't when the goal is appearance, general health or a sense of well-being.1, 2 The prescribing clinician's fees can count too.2
Compounded tirzepatide or semaglutide is mixed by a pharmacist for an individual patient and is not FDA-approved. It faces no separate IRS test: like any prescription drug, it must be prescribed and legally obtained.2, 3, 4
Each company decides whether its checkout takes the card. On October 3, 2026, Ro said it doesn't take HSA or FSA cards, while LillyDirect and NovoCare Pharmacy, the drugmakers' pharmacy services, said they do.5, 6, 7 But the drugmakers' terms for some of their self-pay prices say buyers agree not to seek payment or accept reimbursement from a health care reimbursement account, and Lilly's other terms count HSAs and FSAs as such accounts.8, 9 Check which prices these terms cover before you pay that way.
Where the card isn't taken, you can pay another way and claim the money back with an itemized receipt. An FSA, though, pays only for what your employer's plan covers, and not in advance for months you haven't received.10, 11
CareCredit is a credit card, not coverage. Its "no interest if paid in full" offers, for 6 to 24 months, apply only in its network and at select retailers. If any of the promotional balance is left when the promotion ends, you're charged all the interest that built up from the purchase date, not just interest on what's left.12, 13, 39
This is general tax and consumer-credit information, checked against IRS publications, federal agencies and each company's terms on October 3, 2026. It isn't tax, legal or financial advice: check your plan's rules with its administrator, ask a tax professional about your return, and read a card's terms before you apply.

The IRS test: a diagnosed disease, not a particular drug
IRS Publication 502, the agency's guide to medical expenses, counts money spent to lose weight "if it is a treatment for a specific disease diagnosed by a physician (such as obesity, hypertension, or heart disease)," but not weight loss for "the improvement of appearance, general health, or sense of well-being," or diet food.2 An IRS FAQ, last reviewed September 23, 2026, applies the same test to HSAs and FSAs.1 And in Revenue Ruling 2002-19, the IRS wrote that "obesity is medically accepted to be a disease in its own right."14
-
The medicine counts if it is prescribed, meaning it requires a doctor's prescription.2
-
The clinician counts: payments to physicians and other medical practitioners qualify, and HealthEquity, an account administrator, says this can include telehealth visits.2, 10
-
Your family counts: HSA and health FSA money can pay for a spouse's and dependents' care, and a health FSA can also cover your child under 27.11
The IRS list is a tax rule, not a prescribing rule. Zepbound (tirzepatide) and Wegovy (semaglutide) are FDA-approved, with a reduced-calorie diet and more physical activity, for weight reduction in adults with obesity, or with overweight and at least one weight-related condition, among other uses.15, 16 High blood pressure without obesity or overweight isn't one of these uses, so a GLP-1 for it would be off-label. The label warnings are below.
If your goal is appearance or general health, an FSA can't reimburse it, and an HSA withdrawal for it is taxed, possibly with an extra 20%.2, 11 If you don't fit the approved uses, or your goal is appearance or general health, talk with your own doctor before you choose a seller or a way to pay. PlexusDx is one of those sellers, and our page for people who aren't obese or overweight lists questions to ask.
Compounded and "research use" products
Publications 502 and 969 don't mention compounded drugs, and Treasury regulations count only medicine that was "legally procured."2, 11, 4 Whether a compounded GLP-1 was made and sold legally depends on FDA's rules. For example, a pharmacy may not regularly, or in large amounts, compound what is essentially a copy of an approved drug unless the prescriber decides that a change made for you produces a significant difference for you. FDA's guidance adds that a lower price doesn't show that.17 Our provider guide explains the rules for compounded GLP-1s.
Qualifying for HSA or FSA payment says nothing about quality. FDA does not review compounded drugs for safety, effectiveness or quality before they are marketed. It says they should be used only by patients whose medical needs an FDA-approved drug cannot meet.18
Products labeled "for research purposes" or "not for human consumption" are different. FDA has warned companies that sold semaglutide or tirzepatide that way and urges consumers not to buy them; our provider guide lists offers to walk away from.18 The tax rules exclude illegal treatments, and generally a prescription drug ordered from another country unless it was imported legally.2
Calling a product a "peptide" changes nothing: Publications 502 and 969 don't use the word, so the same test applies.2, 11 A GLP-1 that isn't prescribed for you and dispensed by a state-licensed pharmacy is the kind of online product FDA warns may be counterfeit, contain the wrong or harmful ingredients, or have too much, too little or none of the drug.18
Label warnings for you and your family
Go through these points with the prescriber for anyone your HSA or FSA covers. They come from the FDA labels for Zepbound and Wegovy.15, 16
Children. Start with the child's own doctor. Wegovy injection is FDA-approved, with a reduced-calorie diet and more physical activity, for weight reduction in children 12 and older with obesity, except at its 7.2 mg dose (Wegovy HD).16 Wegovy HD, Zepbound and Wegovy tablets are approved only for adults, so using any of them under 18 would be off-label.15, 16 Compounded tirzepatide and semaglutide are not FDA-approved for anyone.18
Pregnancy and birth-control pills. Either drug may harm an unborn baby. For weight loss, both labels say to stop when a pregnancy is recognized, and Wegovy's says to stop at least 2 months before a planned pregnancy. Breastfeeding is not recommended with Wegovy tablets. Zepbound can make birth-control pills less effective, so its label advises a non-pill or added barrier method for 4 weeks after starting and after each dose increase.15, 16
Buying several months at once. FDA's advice for compounded injections affects what you get for your money: throw a multiple-dose vial away within 28 days of first use, even if medicine is left and even if the pharmacy's instructions say it lasts longer. Use a new sterile needle and syringe for every dose, and don't use any injectable GLP-1 that arrives warm or without enough refrigeration.18 Our guide covers checks when the medicine arrives.
One person per prescription. Medicine bought for one family member is for that person only: both Medication Guides say not to give it to anyone else, even someone with the same condition. They also say never to share a pen or needles, even after changing the needle, because that can pass on a serious infection. That includes the Zepbound KwikPen and Wegovy FlexTouch, which each hold four weekly doses.15, 16
Compounded tirzepatide or semaglutide has no FDA label, so go through every point here with your prescriber anyway. FDA says many of its reported side effects look like the approved drugs'. Its side effects are likely underreported, because federal law doesn't require state-licensed pharmacies to report them unless they are outsourcing facilities (compounders registered with and inspected by FDA). Some of those reports, including some that needed hospital care, may be related to dosing mistakes with compounded semaglutide injections.18, 19
Who must not take them. Both labels carry a boxed warning: the drugs caused thyroid C-cell tumors in rodents, and it is not known whether they cause these tumors, including a type of thyroid cancer called medullary thyroid carcinoma (MTC), in people. Neither is for anyone with a personal or family history of MTC or with multiple endocrine neoplasia syndrome type 2 (MEN 2, a hormone-gland condition). Neither is for anyone with a known serious allergy to the drug or its ingredients, and neither is recommended with severe gastroparesis (very slow stomach emptying).15, 16
Other serious risks. Both labels warn of:
- Pancreatitis, including fatal cases, and gallbladder problems.
- Nausea, vomiting and diarrhea, which are common and can be severe. The fluid loss can lead to kidney injury, sometimes needing dialysis.
- Low blood sugar, most often with insulin or a sulfonylurea (a type of diabetes pill). It has also been reported in adults without type 2 diabetes.
- Serious allergic reactions.
- Worsening diabetic eye disease in people with type 2 diabetes, so anyone with a history of it should be monitored.
- Rarely, food or liquid entering the lungs during anesthesia or deep sedation, so tell every doctor and dentist before a planned procedure.
Wegovy can also raise resting heart rate. Both drugs slow stomach emptying, which can change how pills are absorbed. Zepbound's label names the blood thinner warfarin, and semaglutide tablets raised levothyroxine (thyroid hormone) levels by about a third in a study. Give your prescriber a list of everything you take, and don't combine either drug with another GLP-1, compounded tirzepatide or semaglutide included.15, 16
Signs to act on.
-
Stop the medicine and get medical help right away for a serious allergic reaction: swelling of the face, lips, tongue or throat, trouble breathing or swallowing, severe rash or itching, fainting or dizziness, or a very fast heartbeat.
-
Stop it and call your prescriber right away for severe stomach pain that won't go away, sometimes felt in the back.
-
Call your prescriber right away about nausea, vomiting or diarrhea that won't stop (and drink fluids), or any sign of gallbladder problems: upper-stomach pain, fever, yellow skin or eyes, or clay-colored stools.
-
If anyone in your family may have taken too much, call the prescriber or Poison Help at 1-800-222-1222, or go to the nearest emergency room right away. Wegovy's guide says too much can cause severe nausea, vomiting and low blood sugar.
-
Also tell your prescriber about a lump or swelling in the neck, hoarseness, trouble swallowing or shortness of breath, or low blood sugar signs such as shakiness, sweating or confusion. Tell them about vision changes if you have type 2 diabetes and, on Wegovy, a racing heartbeat at rest that lasts several minutes.
These come from the approved drugs' Medication Guides, which list more; compounded products have none.15, 16
Paying with the account's card, or paying first and claiming later
You can pay with your HSA or FSA card, or pay another way, keep the itemized receipt and reimburse yourself.10 An HSA card payment counts as a withdrawal like any other.11 Even a card payment can lead an FSA administrator to ask for receipts, unless it meets the IRS's methods for checking card payments.11
October 3, 2026: each company's HSA and FSA terms, from its own pages
| Company |
What its pages say |
| Ro (telehealth) |
No card. No HSA or FSA cards "at this time"; gives a detailed receipt and prescription copy "for possible reimbursement"5, 20
|
| Hers (telehealth) |
Card may need extra steps. Recommends paying by regular card, then claiming21
|
| Patiently (HSA Store's GLP-1 program) |
Card use not described. Says "100% HSA eligible" and "FSA/HSA eligibility may vary by plan"22
|
| LillyDirect (Lilly's pharmacy service) |
Takes cards, with a KwikPen limit. Calls Zepbound "HSA/FSA eligible," but KwikPen self-pay buyers agree not to seek payment from a "healthcare reimbursement account"6, 8, 23
|
| NovoCare Pharmacy (Novo Nordisk's pharmacy for Wegovy) |
Takes cards, with a self-pay limit. Accepts payment from "FSA/HSA funds," but self-pay buyers agree not to seek payment from a "health care reimbursement account"7, 9
|
What the drugmakers' self-pay terms say. Lilly's terms for the Zepbound KwikPen at its self-pay price say buyers agree not to seek payment or accept reimbursement for those costs from "any insurance plan, healthcare reimbursement account, or other third-party payer." In Lilly's terms for its savings card for people with commercial insurance, health savings and flexible spending accounts are listed as kinds of "healthcare reimbursement accounts."8 Novo Nordisk's terms for Wegovy's self-pay prices, which NovoCare Pharmacy links from its price list, say the same of any "health care reimbursement account."7, 9 LillyDirect's FAQ adds that if you have insurance and choose self-pay for any medicine, "you agree not to seek reimbursement from your insurance or any third-party payer."6
So the pharmacies' card policies point one way and the drugmakers' self-pay terms another, and LillyDirect's "HSA/FSA eligible" label adds just one caveat: "Eligibility may vary by plan."23 Before you use HSA or FSA money at a self-pay price, ask the pharmacy and your plan administrator how these terms apply to you.
Policies change, so check before you pay, and a company's "HSA eligible" label isn't an IRS ruling. Our page on GLP-1 prices without insurance lists the drugmakers' cash prices, and our comparison of GLP-1 telehealth programs covers more programs. PlexusDx's answers are below, and the label warnings apply whichever company you use.
If your health plan might cover the drug, or has said no
Check first whether your health plan covers the drug. If it does, your HSA or FSA can pay your share, such as the deductible, copay or coinsurance.11 A drugmaker's cash price is paid outside your insurance: NovoCare says "any money spent" that way won't count toward your deductible or out-of-pocket limits, and Lilly's KwikPen self-pay terms say the same.7, 8 Both drugmakers' self-pay terms also rule out seeking payment from a health care reimbursement account, as explained above.8, 9
If your plan says no, your account can still pay when the IRS test is met: an HSA covers qualified expenses insurance doesn't, and an FSA covers what its plan allows.11 Our page on Zepbound prior authorization (a plan's approval before it pays) explains how to ask for it and how to appeal a denial. Our price page shows which drugmaker savings offers each kind of coverage can use.
Paperwork your plan may ask for
-
An itemized receipt. FSAFEDS, the federal employees' FSA program, wants the patient's name, the provider's name, the date of service, a description of what was bought, and the cost. A pharmacy prescription receipt is enough for a prescription; credit card receipts, cancelled checks and balance-forward statements typically lack those details.24
-
A copy of the prescription. Administrators may ask for one, and some companies provide it.10, 20
-
A letter of medical necessity, if your plan asks (see letters below).10
-
A breakdown of any bundled fee. If one charge covers the medicine, clinician visits and other services, ask for a receipt that lists each part.
With an HSA, you usually send nothing when you pay or reimburse yourself, but you must keep records showing each withdrawal paid for qualified medical expenses, with your tax records.11, 10 With an FSA, you usually submit documents with each claim, including a statement from an independent third party showing the expense and its amount.10, 11
Letters of medical necessity
Plans differ. FSAFEDS, for example, pays for a prescription with a detailed receipt. For a weight-loss program that treats a medical condition, it also wants a letter signed by your doctor, and it won't pay for one aimed at general health.25, 26 HSA Bank says such a program may be eligible with a letter, only if it treats a disease diagnosed by a physician.27 So if one fee covers the medicine, the clinician and support, ask your administrator whether it counts as a prescription or as a weight-loss program.
WEX, a benefits administrator, and Fidelity, an HSA custodian, say a letter typically includes:
- your name and diagnosis;
- the recommended treatment and why it is medically necessary;
- how long treatment will last;
- the provider's name, credentials and signature, and the date.
Most letters are valid for one year, and some plans want them renewed sooner.28, 29
A letter records a diagnosis; it can't create one. The IRS has warned that notes from doctors "based merely on self-reported health information" don't turn food, wellness or exercise costs into medical ones. A plan that pays non-medical expenses isn't qualified, so all its payments, even for real medical costs, count as income.30 If your plan asks for a letter, ask the physician who diagnosed your condition and manages your treatment.

The plan can't reimburse it11
|
Since January 1, 2026, bronze and catastrophic plans offered on the Marketplace count as HSA-compatible, including when you buy the same plan outside the Marketplace (IRS Notice 2026-05).33 An FSA plan can offer a grace period (up to 2½ months after the plan year to spend leftover money) or a carryover of up to $680 of unused 2026 money, but not both. It may also cover only some of what the IRS allows.11, 31, 27 One FSA advantage: you can use the full year's amount before it has all come out of your pay.11
Once you enroll in Medicare, you can't add money to an HSA, but money already in it can still pay qualified medical expenses tax-free.11 With Medicare Part D, check first whether Medicare's temporary GLP-1 Bridge covers your medicine for a $50 monthly copay; our UnitedHealthcare page explains who qualifies.34
Four ways a claim can go wrong
-
Prepaying several months with FSA money. An FSA can reimburse only expenses incurred during your coverage period, and it can't pay future expenses in advance.11 Some programs charge for several months in one payment,21 and your FSA may not pay back the months you haven't received yet, so ask your administrator before you buy. Our program comparison shows how programs bill.
-
Treatment that started before your HSA existed. Expenses incurred before your HSA is established don't qualify for it, now or later.11
-
Counting on a limited-purpose FSA. The kind offered alongside an HSA is restricted to items such as dental and vision care plus preventive care, so check your plan before relying on one for a prescription.11, 27
-
Claiming the same cost twice. An amount paid from an HSA or FSA can't also be deducted on your tax return.1, 2
What the tax break is worth, worked out
FSA money taken from your paycheck skips federal income tax and payroll taxes (Social Security and Medicare tax, 7.65% of most employees' wages).11, 35 HSA money that goes in through your employer's payroll plan (a cafeteria plan) can be left out of your income and generally skips payroll taxes too. Money you deposit in an HSA yourself is deductible even if you don't itemize. But the IRS describes only money that goes in through an employer as generally free of payroll taxes.11
Take a single filer in 2026 whose taxable income falls in the 22% federal bracket ($50,400 to $105,700) and whose wages are below the $184,500 cap for Social Security tax.31, 35
2026 example: federal tax saved by a single filer in the 22% bracket
| How the money goes in |
Per $100 |
Full 2026 account |
| FSA through payroll: no 22% income tax or 7.65% payroll tax |
$29.65 |
About $1,008 on $3,400 |
| HSA through payroll: no income or payroll tax |
$29.65 |
About $1,305 on $4,400 |
| HSA deposit you deduct yourself: income tax only |
$22.00 |
$968 on $4,400 |
The arithmetic: 22% plus 7.65% is 29.65%, so $3,400 × 0.2965 = $1,008.10 and $4,400 × 0.2965 = $1,304.60. A deposit you make yourself saves $4,400 × 0.22 = $968 if it all falls within the 22% bracket. It is an illustration, not a prediction, and assumes every dollar goes to qualified medical expenses.11, 31, 35
Three things change the result. Unspent FSA money is generally lost (beyond any grace period or carryover your plan offers), so the saving applies only to what you use.11 Social Security tax stops at $184,500 of wages.35 State income tax is also left out. Whether your state exempts the money depends on its own law, so check your state tax agency's guidance before adding a state rate.
No HSA or FSA? You can deduct medical costs only if you itemize, and only the part above 7.5% of your adjusted gross income; with an adjusted gross income of $60,000, only costs above $4,500 count. A charge on a credit card counts in the year you make it, not when you pay off the card.2
CareCredit: a credit card, not coverage
CareCredit is a credit card for health and wellness costs, issued by Synchrony Bank, which sets the credit requirements. Checking whether you prequalify doesn't affect your credit score, but applying after an offer brings a hard inquiry that may.12 If an expense qualifies, you can pay with the card and then reimburse yourself from your HSA or FSA with an itemized receipt, unless the seller's terms rule that out (see the drugmakers' self-pay terms).11, 10
Where it works
CareCredit's weight-loss page lists tirzepatide and semaglutide among treatments its card can pay for "at a location in the CareCredit network."36 Its pharmacy page names Walgreens, Walmart and Sam's Club pharmacies in store, and Duane Reade in the New York area.37 Not every location or provider offers every promotion; where none applies, standard terms do.37, 12 Check a clinic or online program with CareCredit's Acceptance Locator, and ask the company, before you apply.13
Do LillyDirect, Hers or the other companies in the table take it? The payment pages we checked don't mention CareCredit.6, 23, 5, 20, 21, 22, 7 LillyDirect takes all major credit cards. Of CareCredit's two cards, only the Rewards Mastercard works everywhere Mastercard does. Even then, promotional financing applies only in the CareCredit network and at select retailers; anywhere else, a Rewards Mastercard purchase gets the card's standard terms.6, 12 Online applications are considered for the Mastercard first, but applications made at a provider's office are for the standard card only.12
Deferred interest, with numbers
For new accounts, CareCredit lists a 32.99% purchase APR (annual percentage rate), a 39.99% penalty APR and a $2 minimum interest charge, "as of 5/30/2024" and still shown on October 3, 2026. Existing cardholders should check their agreement.38, 12 Its "no interest if paid in full" promotion runs 6, 12, 18 or 24 months on purchases of $200 or more at enrolled providers and select retailers. Interest builds from the purchase date and is all added if the promotional balance isn't paid in full in time.13 The Consumer Financial Protection Bureau (CFPB) says it is usually figured on each month's balance, and that being more than 60 days late with a minimum payment can also cost you the deal.39
October 3, 2026 rates: $1,200 on a 12-month "no interest if paid in full" promotion
| How you pay |
Still owed when the promotion ends |
Interest added |
| $100 a month, every payment on time |

$0 |
| $100 a month, but the 12th payment arrives late |
$100 |
About $214 |
| $80 a month |
$240 |
About $251 |
How we worked it out: 32.99% divided by 12 is about 2.749% a month, charged on each month's balance. The second row's 12 balances add up to $7,800 (about $214 in interest) and the third's to $9,120 (about $251). Real statements will differ, because they follow the card's own billing cycle and balance method, and a late payment can also bring a late fee.39, 38, 13
-
Equal payments work only on a clean account. The $100 is CareCredit's suggested payment, the purchase divided by the months, and it clears the balance only with no other balances and every payment on time.13 Minimum payments may not do it; the CFPB says they probably won't and advises paying off well before the deadline.13, 39
-
Other balances change where your money goes. Payments above the minimum usually go to a higher-rate balance first, except in the promotion's last two billing cycles.39
-
Monthly refills can lose the grace period, the time between the end of a billing cycle and the due date when paying in full can avoid interest.40 New purchases made while a promotional balance is open might lose it unless you pay the whole card balance by the next due date.39
-
Charges under $200 don't qualify for the 6- to 24-month "no interest if paid in full" promotion.13
As of October 3, 2026, CareCredit says purchases of $1,000 or more may qualify, at providers that offer it, for fixed payments at a reduced APR, from 17.90% over 24 months to 20.90% over 60 months (from $2,500). Interest runs from the purchase date.12, 13 Over 24 months, each payment is 4.9876% of the purchase rounded up to a whole dollar: $60 a month and about $236 in interest on $1,200, with the last payment or two smaller because of the rounding.13
The CFPB notes that a medical financing product can cost more than credit you already have, and that missed payments can show up on your credit report.41
HSA, FSA and CareCredit if you enroll through PlexusDx
Here are the answers to the payment questions above if you enroll through PlexusDx, the publisher of this page, as of October 19, 2026. Its programs are for adults 18 and older. They use compounded medication, which is not FDA-approved.18 They are self-pay: PlexusDx does not bill health insurance.
Taking the card doesn't make a charge qualify: the IRS test above and your plan's rules decide that, for PlexusDx as for any company.1, 11 Whether compounded medicine was legally obtained depends on the rules above.4, 17 Our provider guide gives PlexusDx's answer on whether the prescribers record why a compounded product, rather than an FDA-approved one, meets each patient's needs.
-
Paying with an HSA or FSA: PlexusDx's Terms of Service say: "PlexusDx accepts eligible HSA/FSA payment methods and can provide itemized documentation. Individual eligibility and reimbursement are determined by the applicable plan administrator and law."
-
Receipts and card statements: One plan price covers clinician care, including live consultations when clinically required and ongoing oversight; the compounded medication and its dispensing; applicable injection supplies; standard shipping; and PlexusDx's platform and support services. There is no separate membership fee. Because one fee covers all of this, the advice above on bundled fees and letters of medical necessity applies. Checkout lists the purchase as your plan, card statements show the charge from PlexusDx, and the checkout notes that HSA and FSA cards are accepted.
-
How and when you're charged: Your payment method may be verified when you enroll, but the treatment charge goes through only after a clinician approves treatment; if it isn't approved, you owe $0. The 1-month plan is charged monthly, and the 3-, 6- and 12-month plans are charged in full, up front, after approval, so the FSA rule above applies to them.
-
Renewals, cancelling and refunds: Plans renew automatically for the same length unless you cancel or pause them in PlexusDx's self-service portal before the next renewal charge. After approval, until the prescription is sent to the pharmacy, you can ask to cancel for a full refund; after that, a change of mind generally doesn't qualify, and cancelling a prepaid plan stops its renewal without a prorated refund (money back for the unused part) of the current term. If your clinician decides to stop treatment for medical reasons, though, PlexusDx refunds prepaid months not yet dispensed, at the monthly-equivalent rate you actually paid. PlexusDx's Terms of Service and Refund & Cancellation Policy have the full rules, and our program comparison explains how programs handle renewals and refunds.
-
CareCredit and other financing: PlexusDx's Terms of Service and Refund & Cancellation Policy don't mention CareCredit or any other financing. Before you apply for CareCredit to pay for PlexusDx treatment, check CareCredit's Acceptance Locator, as described above.
-
Prescribers and brand-name medicines: Clinicians from Lone Star Virtual Health, PlexusDx's provider team, make the medical decisions, including whether to prescribe; PlexusDx does not practice medicine. PlexusDx does not sell or ship brand-name medications. If you would prefer a brand-name, FDA-approved medication, your provider may write a prescription you can fill at the pharmacy of your choice, such as LillyDirect for Zepbound or NovoCare Pharmacy for Wegovy; read the drugmakers' self-pay terms before you pay a self-pay price with HSA or FSA money.
Go through the label points above with your prescriber for compounded medicine too.

How we made this page
The rules on this page come mainly from IRS Publications 502 and 969, Revenue Ruling 2002-19, the IRS's 2024 warning about doctors' notes and its inflation figures for 2026 and 2027, FSAFEDS's claim rules, Lilly's and Novo Nordisk's self-pay terms, CareCredit's own terms, the CFPB's explanations of deferred interest and grace periods, and the Zepbound and Wegovy labels. On October 3, 2026, AI tools collected those documents and the payment pages of Ro, Hers, Patiently, LillyDirect and NovoCare Pharmacy, copied out the sentence behind each statement, and drafted the text and tables.
A script reran the tax and interest arithmetic in the worked examples, and automated checks compared each supporting quote with the text we retrieved from its source. AI reviewers then checked each statement against its source and looked for safety, regulatory, search-policy and reader problems, and AI editors reopened the sources and revised the page in response. These checks are not a tax, legal or medical review.
This page replaces five older PlexusDx posts about paying for GLP-1 treatment with an HSA, FSA or CareCredit. None of their text was carried over, and what they said about PlexusDx's own payment options is replaced by the answers in the PlexusDx section, as of October 19, 2026.
The payment table covers the companies people named most often in the searches that showed those posts: Ro, LillyDirect, Hers and Patiently were each named in queries that brought the posts at least 100 of their 26,408 Search Console impressions from July 2025 to September 2026. NovoCare Pharmacy is added for readers who asked about Wegovy. CareCredit, named in queries with about 1,700 of those impressions, has its own section. We did not open accounts, apply for credit or try any company's checkout for this page, and it has no affiliate links. Other companies' terms are cited to their own pages; PlexusDx's terms are ours, as of October 19, 2026.
Jay Hastings reviewed and approved this version on October 19, 2026. Dr. Asad K. Niazi, MD, MPH, reviewed the medical content on October 17, 2026. He is co-founder and CEO of Lone Star Virtual Health, the company that provides PlexusDx's prescribing clinicians, so he has a business relationship with PlexusDx. PlexusDx sells compounded GLP-1 treatment, so we have a financial interest in this topic. Read our editorial policy.
