Medicare covers primary or secondary surgical dressings:

• Used to protect or treat a wound
• If needed after debridement of a wound

The patient’s medical records should include clinical information to demonstrate reasonable and necessary need for the type and quantity of surgical dressings. Providers must evaluate the wound monthly and update the record, unless they document why they can't do a monthly evaluation and how they're monitoring the patient's ongoing use of dressings.

For more information, see the Surgical Dressings - Policy Article.
