Medicare Coverage & Payment
- CMS short descriptor: Woundplus e-grat, per sq cm
Source: CMS HCPCS Level II release. Coverage codes indicate how Medicare treats the code, not whether a specific claim will be paid; payer policy and documentation still govern.
Code Set: Removed from the code set — not valid on or after July 1, 2024.
