CPT Code 97530 Description
“CPT 97530 – Therapeutic Activities, direct (one-on-one) patient contact (use of dynamic activities to improve functional performance), each 15 minutes” – Source
Time-Based CPT Code
CPT Code 97530 is a time-based code. This means that each minute of time required to deliver the service must be recorded and accounted for. Each minute my be delivered “face-to-face” by the rendering provider and those minutes of time may not be billed for any other patient.
In order to bill one complete unit of care, the service must be delivered for a minimum of 8 continuous minutes.
By definition, time-based CPT codes are expected to average 15-minutes.
Two billable units of a time-based code may not be billed until the provider has passed the midway point of the next unit of time.
Adding Minutes of Time-Based CPT Codes
For example: If 1 unit of CPT Code 97530 can range between 8 and 22 minutes, the second unit may not be billed until the 15-minutes of the first unit plus the 8 minutes of the second unit has been delivered. This totals 23 minutes of time.

Does CPT Code 97530 Require a 59 Modifier?
When billing CPT Codes some payers will indicate coding pairs that require a 59 modifier to indicate that the two procedure codes are unique or distinct.
In this 2020 WebPT article titled How to Handle Modifier 59 Denials for 97530 and 97140, the author discusses how a 59 modifier was required for the line item CPT Code 97530 when billed on the same date of service as CPT Code 97140 or the CPT Code 97530 would not be paid.
Updates to the National Correct Coding Initiative Edits (NCCI) have removed this pairing and as of 2022, a 59 modifier is not required when billing CPT Code 97530 and CPT Code 97140 on the same treatment day.

Ohio Bureau of Worker’s Compensation | $52.82 |
You can see from the table above, reimbursement rates will vary dramatically based on third-party payer and location.
When is CPT Code 97530 Used in Treatment?
Case Study
A patient is referred to physical therapy status post left total knee arthroplasty. This patient is 4 days post-op and has been discharged to home for mobile, outpatient therapy services.
Upon the initial evaluation it has been determined that prior to surgery, this patient was independent with ascending and descending a staircase within the home. It has also been determined by the therapist that a full return to premorbid status is reasonable.
CPT Code 97530 treatment might include a forward step up to 8-inch step with the use of one hand on the handrail. Three sets of 5 repetitions on each leg. Verbal and tactile cues may be utilized to help this patient learn proper sequencing. A review of the “up with the good and down with the bad” auditory reminder may have been required. Next, a step-down exercise from a 4-inch step may be appropriate utilizing both upper extremities for support and contact guard assistance. These two exercises may have started at 09:23 and ended at 09:32 for a total time of 9 minutes. As long as the therapist or therapist assistant under the supervision of the therapist was face to face with this patient during this treatment intervention, a single unit of CPT Code 97530 may be billed.
