We have been submitting claims to medicare for nerve conduction study and they have been denied as "medically unnecessary". Example of one clinical note:

"This is a 71-year-old gentleman with pain in his legs.
–
DESCRIPTION OF RECORD: Right and left lower extremities were
examined. Right and left peroneal nerve distal latencies, amplitudes,
and conduction velocities were within normal limits. Right and left
tibial nerve distal latencies, amplitudes, and conduction velocities
were within normal limits. Right and left sural nerve distal
latencies, amplitudes, and conduction velocities were within normal
limits. F-wave studies performed on tibial and peroneal nerves showed
100% F-wave occurrence in all nerves tested.
–
IMPRESSION: Unremarkable nerve conduction study of the lower
extremities."

This was billed as a 95909-26 with ICD 10 code M79.604
if there is something missing in the documentation or should it be coded differently, I would like to know so I can inform the provider.
Please advise. Thanks everyone
