Question: I know that CPT^® 2027 will include new and revised codes for autonomic nerve system function testing; are there any other new or revised CPT^® codes neurology practices should note for 2027?

Answer: If your neurology practice conducts sleep studies, there are six new codes to represent these services. They are all for unattended sleep studies, though there are two distinct code sets.

The first new sleep study set consists of the following codes:

• 95843  (Unattended sleep study, set-up, data acquisition and technical analysis; low complexity of 3-4 channels that generate at least 3-5 parameter categories)
• 95844  (… moderate complexity of 5-10 channels that generate at least 6-8 parameter categories)
• 95846  (… high complexity of 11 or more channels that generate at least 9 parameter categories)

This is the second set of new sleep study codes:

• 95847  (Unattended sleep study, interpretation and report by a physician or other qualified health care professional; low complexity of 3-4 channels that generate at least 3-5 parameter categories) 
• 95848  (… moderate complexity of 5-10 channels that generate at least 6-8 parameter categories)
• 95849  (… high complexity of 11 or more channels that generate at least 9 parameter categories)

Here are a few notes on the new codes:

• Check with each individual payer to see if they have implemented the new codes. Don’t assume that every payer will have every new code loaded into its system on January 1.
• As with all new codes, there might be some confusion about how to correctly employ them; stay tuned for more guidance from CPT^® as 2026 winds down.
• Check with each individual payer before reporting the new sleep study codes; payers will be getting used to the new codes, too, and they might not all observe the same policies on reporting (for example, prior authorization, required diagnoses, documentation, etc.).
• Include all the documentation you think is relevant when submitting new codes. Then, follow documentation requirements as they become available from each payer.
• Look out for updates and guidance regarding the new codes from your payer.
