The short answer

Ovena's collagen wound dressings and 20-30 mmHg compression are commonly eligible expenses for a Flexible Spending Account (FSA) or Health Savings Account (HSA). Your plan administrator decides, and some plans ask for a Letter of Medical Necessity first.

Administrators work from IRS rules (Internal Revenue Code Section 213(d) and IRS Publication 502). To make substantiation easy, every Ovena order can include an itemized receipt with the applicable HCPCS supply code on request. We are not tax advisors, so confirm the specifics with your own FSA or HSA administrator.

FSA vs HSA: the quick version

Both accounts let you spend pre-tax dollars on qualified medical expenses. The difference is how the money is held.

• FSA (Flexible Spending Account) — employer-sponsored, funded with pre-tax payroll dollars, generally use-it-or-lose-it within the plan year (some plans allow a small rollover or grace period). Usually comes with a debit card.
• HSA (Health Savings Account) — paired with a high-deductible health plan, funded with pre-tax dollars, balances roll over year to year and stay yours even if you change jobs.

For both, qualified medical expenses follow the definition in IRS Publication 502. Wound care supplies and medical-grade compression used to treat a condition generally fall inside that definition.

What is eligible at Ovena

The table below is a general guide, not a coverage guarantee. Your plan administrator has the final say.

General-wellness purchases are not eligible. The items above are medical supplies bought to treat or manage a specific condition; whether your plan reimburses a given item is still the administrator's call.

How to pay: card vs reimbursement

You have two straightforward paths:

1. Use your FSA/HSA debit card at checkout. Most cards run like any other card. If a card is declined because of the merchant category, simply pay another way and reimburse yourself (path 2).
2. Pay out of pocket, then submit an itemized receipt. Request an itemized Ovena receipt (product description plus HCPCS code) and upload it through your administrator's portal or app.

Either way, keep the itemized receipt. Administrators can ask for substantiation months later, and a receipt that names the product and its HCPCS code is usually all they need.

When you need a Letter of Medical Necessity

Some plans require a Letter of Medical Necessity (LMN) for products that have both medical and everyday uses. Compression is the most common example, because compression socks are sometimes bought for comfort rather than treatment.

An LMN is a short note from your clinician that states your diagnosis and confirms the product is medically necessary. Most clinicians sign one in a couple of minutes. Ovena provides a clinician-ready LMN template you can bring to your appointment.

Putting the HCPCS code on your claim

A HCPCS code is the standardized supply code that payers and benefit administrators recognize. Including it on your receipt or claim removes guesswork and speeds substantiation. For Ovena collagen, the two codes that matter are A6021 for the sheet dressings and A6010 for the powder.
