Prior Authorization
No Prior Auth Required
Code is covered without prior authorization (high confidence)
Documentation Required
- When routine foot care needs to meet one of the exclusions, include the applicable Q modifier on the claim: Q7 for 1 Class A finding, Q8 for 2 Class B findings, and Q9 for 1 Class B plus 2 Class C findings.
- For all foot-care claims report an appropriate foot/toe location modifier (e.g., LT, RT, TA, T1-T9) to identify laterality and specific toe when applicable.
- If a significant, separately identifiable evaluation and management service is provided on the same day as routine foot care, append modifier -25 to the E/M claim line.
- Total the number of keratotic lesions debrided and select the most appropriate CPT code 11055-11057 based on that total (example: code 11056 for two to four lesions).
Key Coverage Criteria
- Removal of corns and calluses of the feet must be billed using CPT codes 11055-11057 (paring/cutting of benign hyperkeratotic lesion) and the procedure code that most accurately describes the service performed should be reported.
- Routine foot care and debridement of nails are payable under Medicare Part B when performed in approved places of service (POS 11,12,13,14,19,20[11720/11721 only],21,22,24,31,32,33,49,51,52,53,54,55,56,61,62,65,71,99).
- Debridement of mycotic (onychomycosis/dermatophytosis) nails is covered only when the claim lists a primary diagnosis of dermatophytosis of the nail plus either a secondary systemic condition or an ICD-10-CM code from the LCD 'ICD-10-CM Codes that Support Medical Necessity' indicating secondary infection or pain.
- Procedures to treat onychogryphosis or onychauxis are covered when the primary diagnosis is onychogryphosis or onychauxis and a secondary diagnosis from the LCD indicating secondary infection or pain is also reported.
- Removal of benign hyperkeratotic lesions performed by cutting/parring is reported with CPT 11055, 11056, or 11057 and is the appropriate code set for hyperkeratotic plaques of the foot.
- Removal of epidermal and dermal lesions by shaving is reported with CPT 11300–11313 when full-thickness excision is not performed and when anesthesia and hemostasis are provided.
