Direct/Indirect & Timed/Untimed Definitions

Direct vs Indirect

Direct treatment refers to the time spent by the therapist providing skilled therapy services directly to the patient, such as manual therapy, therapeutic exercises, and neuromuscular re-education.

Indirect treatment refers to the time spent by the therapist on activities that are not directly related to the patient's care, but are necessary for the provision of skilled therapy services, such as modalities.

Timed vs Untimed

Timed codes refer to the services that are provided for a specific amount of time, such as therapeutic exercises or manual therapy, and are billed based on the total time spent providing the service. The time spent providing the service is documented in minutes, and the total number of minutes is divided by the number of minutes in the billing code's time increment (which depends on if your clinic bills by the "Total Minute Rule or "AMA Rule") to determine the number of units to be billed. See our Coding Rule Definition Support Document for more information.

Untimed codes refer to the services that are not provided for a specific amount of time, such as evaluation and management services or interventions that are not timed-based. These services are billed based on the number of units provided, which is determined by the provider's documentation of the service. For example, if a therapist treats a patient with electrical stimulation, they would bill one unit of the corresponding untimed CPT code, regardless of the amount of time spend providing the service.
