E301 – Resection of pinna - with local flap
OHIP Surgical Assists Code — AURAL SURGICAL PROCEDURES · Schedule of Benefits
Resection of pinna - with local flap is a surgical procedure performed in a hospital setting. It involves the removal of part or all of the external ear, typically due to disease or trauma, followed by reconstruction of the area using a flap of adjacent skin and tissue.
When to Use
- Use E301 when performing a formal resection of the pinna for malignancy or trauma that requires reconstruction using a local advancement or rotation flap.
- Select E301 over E300 (Excision of lesion of pinna) when the procedure involves significant tissue loss requiring reconstructive flap closure rather than simple primary closure.
Common Pitfalls
- Billing E301 in conjunction with simple excision codes like E300 is considered unbundling; the flap reconstruction is inclusive of the resection.
- Failure to document the specific type of flap used can lead to audit recovery, as E301 specifically requires a 'local flap' to justify the higher fee compared to simple excision.
Billing Tips
- Ensure the operative report explicitly describes the mobilization of adjacent tissue to create a flap, as this is the clinical requirement that distinguishes E301 from standard excision codes.
