Time-Based Measurement Standard to Follow AMA 

A Change in the Coding of Physical Medicine Service Units

Oct. 23, 2019

As of July 22, 2019 we changed our time measurement standard for billing physical medicine services. We will now follow the American Medical Association (AMA) guidelines for time-based services. These are time-based codes within the Physical Medicine and Rehabilitation section of the Current Procedural Terminology (CPT) code book.

When billing for time-based services use the (CPT) codes in the AMA code book, except as required by federal law for Medicare and Medicaid patients.

As always, it is critical to check eligibility and benefits first, prior to rendering care and services to confirm coverage, network status and other important details. When you check eligibility and benefits online by submitting an electronic 270 transaction through the Availity® Provider Portal or your preferred web vendor portal, you may determine if benefit preauthorization/pre-notification may be required based on the procedure code.

Payment may be denied if you perform procedures without benefit preauthorization when benefit preauthorization is required. If this happens, you may not bill our members.


Please note that verification of eligibility and benefits, and/or the fact that a service or treatment has been preauthorized/pre-notified for benefits is not a guarantee of payment. Benefits will be determined once a claim is received and will be based upon, among other things, the member’s eligibility and the terms of the member’s certificate of coverage applicable on the date services were rendered. If you have questions, contact the number on the member’s ID card.
