All documentation must be maintained in the patient's medical record, be legible, include appropriate patient identification (e.g., full name, dates of service), and be available to the contractor upon request.
The medical record must identify the physician or non-physician practitioner responsible for and providing the care.
The submitted medical record must support the selected diagnosis code(s) and the submitted CPT/HCPCS code must accurately describe the service performed.
When NCSs and NEMG are performed on the same day for the same patient they must be reported on the same claim.

Regional or local nerve blocks performed as part of an operative procedure (e.g., adjunct to or sole means of regional/local anesthesia for the procedure) are not affected by this non-coverage policy and may be billed as anesthesia for the operative procedure.
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).
