Dx Codes List Is Vast for EMGs

Code for NCS only if it accompanies EMG.

The sheer number of conditions that can be treated by needle electromyography (EMG) is staggering.

Here’s the EMG presentations most likely in your practice. Remember to check if the provider also performs a nerve conduction study (NCS), as that will change code choice for the EMG.

Note: This is not a complete list of diagnosis codes for EMG, nor is it a guarantee that the conditions will prove medical necessity for your EMG. Always code to the notes, and check with your provider or payer if you are unsure about a particular EMG/ICD-10 combination.

Code List

In addition to the conditions listed in “Change EMG Coding When NCS Occurs” — carpal tunnel syndrome, herniated disc, amyotrophic lateral sclerosis, myasthenia gravis — here are some of the other conditions that your provider might test for with a needle EMG and/or NCS:

  • A39.82 (Meningococcal retrobulbar neuritis)
