When NCSs and NEMG are performed on the same day for the same patient they must be reported on the same claim.
When billing non-covered services/tests report unlisted neurological CPT 95999 and provide a description of the service/test in block 80 (Part A) or box 19 (Part B) or electronic equivalent; failure to include this information will result in Part A claims being returned and Part B claims rejected.
All documentation must be maintained in the patient's medical record, be legible, include patient identification and dates of service, and include the legible signature of the responsible physician or non-physician practitioner.
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 the medical necessity, the indication for ordering the test(s), and a clear diagnostic impression.

Nerve conduction studies (NCS) without needle electromyography (NEMG) are allowed for individuals being evaluated for carpal tunnel syndrome or tarsal tunnel syndrome when one of the diagnosis codes 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 is reported.
NCS without NEMG is allowed for individuals with significant lymphedema in the affected extremity when diagnosis code I89.0 is reported in addition to the primary diagnosis.
NCS without NEMG is allowed for individuals treated with anticoagulants when diagnosis code Z79.01 or Z79.02 is reported in addition to the primary diagnosis.
Automated nerve conduction testing using the NC-stat (CPT 95905) is allowed only when there is a high pre-test or prior probability of carpal tunnel syndrome and the claim uses diagnosis code G56.01 or G56.02; allowed one service per arm.
If authorized by state law, physical therapists (PTs) are allowed to perform the technical and professional components of nerve conduction studies represented by CPT codes 95907-95913 consistent with a 7A supervision designation (effective 01/01/2013).
If authorized by state law, the technical component of neuromuscular junction testing CPT 95937 (TC) with supervision designation 7A is allowable for PTs consistent with the 7A description (effective 01/01/2013).
