New Medical Policy: General Inflammation Testing

New Medical Policy: Alcohol Injections for the Treatment of Peripheral Neuromas


Morton neuroma is a common and painful compression neuropathy of the dorsal foot that is usually treated with conservative measures, surgery, or minimally invasive procedures. Alcohol injection, a minimally invasive alternative to surgery, causes chemical neurolysis through dehydration, necrosis, and precipitation of the treated area, then ultimately destroys the lesion after multiple injections.

Effective November 1, 2018, BlueCross® BlueShield® of South Carolina and BlueChoice HealthPlan will implement a new medical policy addressing the use of alcohol injection and why it is considered investigational for the treatment of Morton neuroma and all other diagnoses. The policy, CAM 20197 – Alcohol Injections for the Treatment of Peripheral Neuromas, has been published on the Medical Policies pages of the BlueCross and BlueChoice® websites. 

The investigational procedure and diagnosis codes listed in the coding section of the medical policy are below. These codes are included in the medical policy as a general reference tool and may not be all-inclusive:

CPT Description
64632 Destruction by neurolytic agent, plantar common digital nerve
ICD-10 Description
G57.60 – G57.62 Lesion of plantar nerve code range (include Morton metarsalgia

For complete information about CAM 20197, visit our Medical Policies page. Please remember medical necessity is not a guarantee of payment.
