Documentation Required

All documentation must be maintained in the patient's medical record, legible, include patient identification (e.g., full name, dates of service), and be made available to the contractor upon request.
The documentation must include the legible signature of the physician or non-physician practitioner responsible for and providing the care.
The submitted medical record must support the selected ICD-10-CM code(s), the submitted CPT/HCPCS code must describe the service performed, and the record must clearly document medical necessity, the indication for ordering the test, and a clear diagnostic impression.

Key Coverage Criteria

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.
EMG and/or nerve conduction studies are indicated for evaluation of suspected mononeuropathy (single-nerve entrapment or injury).
