Documentation support, made easier to navigate.

What documentation comes with your order

• Itemized receipt with product names and prices, available from your account dashboard.
• HCPCS code reference for our collagen dressings and compression, in the table below.
• Letter of Medical Necessity template, further down this page, ready to bring to your clinician.
• Instructions for use in every box.

FSA / HSA reimbursement

FDA 510(k)-cleared Class II medical devices are commonly FSA/HSA-eligible. Eligibility varies by plan, so confirm with your administrator. Compression socks and the sock aid typically qualify too, but some plans require a Letter of Medical Necessity.

1. Pay with your FSA / HSA card at checkout, if your plan supports SIGIS auto-substantiation, eligibility verifies automatically.
2. If you paid out of pocket, request your order receipt from your account dashboard. Submit it as a claim through your plan administrator (HealthEquity, Optum Bank, etc.).
3. If your plan requires a Letter of Medical Necessity, use the template below.

What varies by payer

Eligibility lists, substantiation rules, documentation requirements, and reimbursement timelines all vary by payer and by plan, and two members of the same administrator can have different eligibility lists. Confirm with your plan administrator before submitting a claim. Ovena provides documentation, not coverage decisions, and we cannot promise that any plan will reimburse a given purchase.

Medicare DME benefits for collagen wound dressings

Collagen wound dressings can be covered under Medicare Part B as a surgical dressing benefit when prescribed for an open wound. The prescription must specify quantity, size, frequency of change, and the wound being treated. Coverage runs through a Medicare-enrolled DME supplier.

Medicare does not typically cover compression stockings for vein disease alone, but may cover them after a lymphedema diagnosis or under certain venous ulcer protocols; coverage criteria are set by Medicare and its contractors.

Letter of Medical Necessity template

Many clinicians can complete one during a routine visit. Bring this to your next appointment:

The LMN should be on the practice's letterhead, dated, and signed.
