Documentation Required
- Medical record must include relevant history, physical exam, and signs/symptoms that required the I&D procedure; diagnostic test results or the symptoms prompting tests must be recorded.
- Pre-operative documentation must record size, location and appearance of the abscess/collection; the operative note must describe the procedure, equipment used, and approximate quantity (e.g., 1 cc, 5 ml) and quality (e.g., serous, bloody, frank pus) of material drained.
- If multiple or repeated I&Ds are performed for the same anatomic area, records must explain reasons for recurrence and measures taken to prevent recurrence; photographic or operative documentation may be requested for patterns suggestive of abuse.
- For services requiring a referring/ordering physician, the name and NPI of the referring/ordering physician must be reported on the claim.
Key Coverage Criteria
- Incision and drainage (I&D) is covered when medical record documents an abscess, hematoma, seroma or other collection of the skin/subcutaneous/accessory structures requiring drainage with signs/symptoms that justify the procedure (e.g., evidence of infection, frank pus, severe pain, or failure of conservative measures).
