Neurology & Pain Management Coding Alert

Question: Can I report one unit of 95861, two units of 95900, and three units of 95904 together? Should I use any modifiers?

Answer: Yes, you can bill 95861 (Needle electromyography; two extremities with or without related paraspinal areas), two units of 95900 (Nerve conduction, amplitude and latency/velocity study, each nerve; motor, without F-wave study) and three units of 95904 (... sensory) together. You don't need to append any modifiers for this code combination.

Many payers will use one line item for the motor or sensory nerve conduction study tests and use box 24G to indicate the multiple units.

For example, if this is the case, you may report 95900 on one line item with "2" in 24G and then report 95904 on a second line with "3" in 24G.

Keep in mind: Most payers will process up to the range of three units per NCS code but may have "difficulties" processing larger numbers of units.

Certain payers may request that you use modifiers -RT (Right side) and -LT (Left side) to separate out into two line items the number of motor and/or sensory performed on each extremity side. For example, the physician performed a total of four motor and six sensory NCS (performed equally on both upper extremities). In this case, you should report:
  95900-RT 2 units
  95900-LT 2 units
  95904-RT 3 units
  95904-LT 3 units.
