Don’t forget that a nerve conduction study (NCS) can affect code choice.
There are a staggering amount of ICD-10-CM codes for diagnoses that can be treated by needle electromyography (EMG).
The following diagnosis code list is not all-inclusive for conditions that may be treated via EMG, and remember that if the provider also performs a nerve conduction study (NCS), the situation may require a different code choice.
Important: 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.
