A4406 HCPCS Level II Code: Ostomy skin barrier, pectin-based, paste, per ounce
HCPCS Level II code, maintained by CMS. Not a CPT code: CPT (HCPCS Level I) is a separate AMA code set that MedCoder does not publish. About HCPCS Level II
Medicare Coverage & Payment
- CMS short descriptor: Pectin based ostomy paste
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.
