Key Coverage Criteria
- No specific coverage indications are stated in this billing/coding guideline; refer to Local Coverage Determination L37641 for covered indications for continuous peripheral nerve blocks (CPNB).
- Routine foot care is covered only when the patient has one or more diagnoses listed in the LCD L33941 “ICD-10 Codes that Support Medical Necessity.”
- Patients with peripheral neuropathy involving the feet (without vascular impairment) are covered when billed with the Group 3 ICD-10 codes appropriate for peripheral neuropathy.
- Patients requiring anticoagulation therapy are covered when billed with the Group 4 ICD-10 codes documenting anticoagulation-related risk.
- Patients with Group 2 (complicating) diagnoses may be covered when the claim includes the appropriate Q modifier (Q7, Q8, or Q9) and the medical record documents the required Class A, B, and/or C findings per the definitions.
- Routine foot care may be covered for patients with peripheral neuropathy of the feet without vascular impairment when the neuropathy is severe enough that care by a non‑professional would place the patient at risk.
