Neurology & Pain Management Coding Alert

Question: What is the appropriate method to bill for "inching" (that is, multiple nerve conduction study [NCS] testing) along the ulnar nerve? The test is very time-consuming, and payers have rejected our claims in the past. Rhode Island Subscriber Answer: "Inching" describes a process of incrementally moving the stimulating electrode away from the recording electrode, which remains stationary through out the test. In this way, the physician can pinpoint the exact location of the problem along the nerve. Because only one electrode is moved, however, you may report only a single unit of 95900-95904, as appropriate, no matter how many "readings" the physician takes.
