What 97035 covers

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 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 indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
