What 97033 covers
Iontophoresis uses an electrical current to move a prescribed medication through the skin to a localized treatment area, often over an extremity with soft-tissue inflammation. Physical therapists and occupational therapists commonly provide it in outpatient rehabilitation settings; dexamethasone is one medication used for this purpose. The service is selected for medication delivery through the skin, not simply because electrical equipment is used during treatment.
Report one unit for each 15 minutes of treatment, supported by documentation of the treatment area, medication, skilled application, and time. Do not count the same treatment minutes toward another timed service. CMS treats this as a therapy service, so a professional-component modifier does not apply. When multiple therapy units are furnished on the same day, CMS reduces practice expense for the second and subsequent units.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

How is this different from electrical stimulation?
Iontophoresis delivers medication through the skin using current. Report 97032 when the service is attended electrical stimulation rather than transdermal medication delivery.
How many units should be reported?
Each unit represents 15 minutes of iontophoresis treatment. Document the treatment time and do not count minutes already assigned to another timed service.
What documentation supports the service?
Record the medication, treatment area, skilled application, and time spent providing iontophoresis. The record should support why medication delivery by this method was part of the rehabilitation treatment.
Should a professional-component modifier be appended?
No. CMS identifies this as a therapy service for which a professional-component modifier does not apply.
How does the therapy multiple procedure reduction affect payment?
CMS reduces practice expense for the second and later therapy units furnished on the same day. The reduction applies to practice expense, not as a reduction to the documented treatment time.
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.
