CPT Code 97012: Is It a Timed or Untimed Code?

Current Procedural Terminology (CPT) codes provide a universal language for healthcare providers to classify medical services and procedures. These standardized five-digit codes are fundamental to accurate reporting, billing, and administrative management within the healthcare system. They ensure clear communication among physicians, patients, and insurance payers, streamlining healthcare claims and reimbursement. The consistent application of CPT codes facilitates efficient claim processing, accurate reimbursement, and medical care review.

Defining CPT Code 97012

CPT code 97012 identifies “Traction, mechanical.” This code describes a therapeutic procedure involving the application of controlled mechanical force to a body part, typically to relieve pain, enhance mobility, or improve flexibility in musculoskeletal conditions. Common applications include spinal decompression for conditions like herniated discs or sciatica, where a pulling force stretches and mobilizes the spine. This mechanical force can be applied to areas such as the head, neck, pelvis, or extremities using specialized equipment.

CPT code 97012 is an untimed CPT code. This means it is billed once per session or encounter, regardless of the specific duration mechanical traction is applied during that visit. For instance, whether performed for 10 or 30 minutes, only one unit of code 97012 can be reported. The code description notes “application of a modality to one or more areas,” indicating that the number of body areas treated within a session does not increase billable units. This classification as a supervised modality means direct, one-on-one patient contact is not continuously required during treatment, though active oversight is necessary.

Billing Untimed Procedures

Untimed CPT codes, also called “service-based” or “per-session” codes, are billed as a single unit per patient encounter or treatment session. This approach applies irrespective of the time spent delivering the service or the number of body areas addressed within that session. For example, a physical therapy evaluation (e.g., CPT code 97001) is billed once per session, even if it takes different amounts of time for various patients. This contrasts with timed codes, where service duration directly influences billable units.

Documentation for untimed codes like 97012 emphasizes medical necessity and a clear description of the service provided, including the type of traction device and areas of application. Detailed time logs are not required for untimed codes, but the record must support the medical necessity and rationale for the therapy. Adhering to payer-specific guidelines is important, as some insurers might have unique requirements for how untimed services are documented or billed. Accurate documentation ensures compliance and helps prevent claim denials or audits.

Distinguishing Timed and Untimed Codes

The difference between timed and untimed CPT codes lies in how they are billed based on service duration. Timed codes are billed in increments, typically 15 minutes, allowing for multiple units to be reported based on the total time a provider spends delivering the service. Examples of common timed codes in therapy include therapeutic exercise (97110), manual therapy (97140), therapeutic activities (97530), and certain constant attendance modalities like electrical stimulation (97032).

For timed codes, the “8-minute rule” is a widely recognized guideline, particularly for Medicare billing. This rule dictates that a provider must perform a timed service for at least eight minutes to bill for one 15-minute unit. If the total time for a single timed service exceeds 22 minutes but is less than 38 minutes, two units can be billed. In contrast, untimed codes, such as 97012 for mechanical traction, are billed only once per session, regardless of the time spent. Correctly identifying whether a CPT code is timed or untimed ensures accurate billing and compliance with payer regulations.
