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.
- Nerve conduction studies (NCS) without needle EMG (NEMG) are allowed for individuals being evaluated for carpal tunnel syndrome or tarsal tunnel syndrome when one of the following ICD-10-CM codes is reported: G56.01, G56.02, G56.03, G56.11, G56.12, G56.13, G56.21, G56.22, G56.23, G57.51, G57.52, or G57.53.
- NCS without NEMG is allowed for individuals with significant lymphedema in the affected extremity when ICD-10-CM code I89.0 is reported in addition to the primary diagnosis.
- NCS without NEMG is allowed for individuals treated with anticoagulants when ICD-10-CM code Z79.01 or Z79.02 is reported in addition to the primary diagnosis.
- Electrodiagnostic testing (EMG and/or nerve conduction studies) is indicated for evaluation of suspected carpal tunnel syndrome.
- EMG and/or nerve conduction studies are indicated for evaluation of suspected radiculopathy.
