Neurology & Pain Management Coding Alert

Question: How should I report limited muscle study EMG for the left and right arms? Can I report 95870-50?

Answer: You should report limited muscle study electromyography per limb using 95870 (Needle electromyography; limited study of muscles in one extremity or non-limb [axial] muscles [unilateral or bilateral], other than thoracic paraspinal, cranial nerve supplied muscles, or sphincters). For testing both the right and left arms, therefore, claim 95870 and place a -2- in the units box of the CMS-1500 or other claim form.

Medicare guidelines stipulate that you should not append modifier 50 (Bilateral procedure) to 95870. When the neurologist tests -bilateral- limbs, however, you may attach modifiers LT (Left side) and RT (Right side) to clarify that you are not double- billing. Or you may append modifier 59 (Distinct procedural service) to the second and subsequent units of 95870 to specify that testing occurred at distinct anatomic locations.
