Physical medicine modality
About 97035: Attended therapeutic ultrasound, each 15 minutes
Therapeutic ultrasound applies acoustic energy to soft tissue with a clinician in constant attendance and is reported in timed 15-minute units.
Therapeutic ultrasound delivers acoustic energy to soft tissue through coupling gel and a moving handheld transducer. Physical therapists, occupational therapists, their assistants, and physicians may use it for localized tendon or muscle symptoms and joint stiffness, commonly in office-based outpatient therapy. The treating clinician remains with the patient throughout application rather than leaving a device running unattended. Phonophoresis, in which ultrasound helps deliver a topical medication, is reported with this code when ultrasound is the delivery method.
Assign 15-minute units using Medicare's timed-service rules, including total timed-treatment minutes when other timed services occur during the visit. Record the actual ultrasound minutes, treated area, treatment settings, and skilled purpose linked to the therapy plan. Use the therapy discipline modifier, GP, GO, or GN, as appropriate. This therapy service has no separately reportable professional or technical component; modifiers 26 and TC are not used. Under the therapy multiple procedure payment reduction, Medicare reduces the practice-expense portion for the second and subsequent therapy units on the same day.

97035 compared with similar codes
Office rate ranges across all CMS payment localities, from the same CMS release.
Choose iontophoresis when electrical current delivers medication. Choose therapeutic ultrasound when sound waves deliver the medication, as in phonophoresis, or when ultrasound is applied without medication.
Attended electrical stimulation applies current and requires constant clinician attendance. Therapeutic ultrasound applies acoustic energy through a moving transducer; do not assign the same treatment minutes to both codes.
Code 76882 is a limited diagnostic ultrasound examination of an extremity that produces images for interpretation. Therapeutic ultrasound treats tissue rather than producing diagnostic images.

97035 billing questions
How are units of this code counted for Medicare?
Medicare uses total timed-service minutes for the visit to determine the allowable units, then assigns units to the timed services performed. Count only minutes of ultrasound actually delivered with the clinician in attendance toward this code.
Is phonophoresis billed with this code or with iontophoresis?
Report phonophoresis with 97035 when ultrasound is the medication delivery method. Iontophoresis uses electrical current to deliver medication and is reported with 97033.
Can a combination ultrasound and electrical stimulation treatment be billed as two timed services?
Do not count the same treatment minutes toward both codes. When both energies are delivered simultaneously through one head, those minutes support only one timed service.
Does a professional or technical component modifier apply?
No. This therapy service has no separately reportable professional or technical component, so modifiers 26 and TC are not used. Use the therapy discipline modifier appropriate to the plan of care.
What documentation supports medical necessity?
Document the treated area, ultrasound settings, minutes of attended treatment, and why skilled treatment is needed. Link the treatment purpose to functional goals in the therapy plan.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
