What 90901 covers

Biofeedback training uses sensors and a display or other feedback method to show a patient a physiologic response, such as muscle activity, while the patient practices changing it. Physicians and trained rehabilitation or behavioral-health clinicians may provide the service in an office or therapy setting. The training must involve active instruction and practice; measurement or monitoring alone does not describe the service. This code covers biofeedback modalities outside the separately specified perineal-muscle training service.

Report 90901 when the documentation identifies the physiologic target, modality, training performed, and the patient’s participation and response. Its descriptor does not define timed increments; the 15-minute perineal-muscle service has separate codes. The CMS global period is 0 days, so same-day preoperative and postoperative care is included. If assistant-at-surgery payment is sought, documentation must support medical necessity; co-surgeons and team surgery are not permitted.

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.

90901 billing questions

When should 90901 be used instead of 90912?

Use 90901 for biofeedback training by a modality not represented by the specific perineal-muscle training service. Code 90912 is for the specified perineal-muscle training and has a timed initial interval.

Is 90901 reported by elapsed time?

The 90901 descriptor does not define timed increments. Do not use its units to represent the additional 15-minute intervals described by 90913.

Does monitoring alone support 90901?

No. Documentation should show that the patient received training and practiced responding to physiologic feedback, not just that a signal was measured or observed.

What should the note document?

Identify the physiologic target and feedback modality, the instruction and practice provided, and the patient’s participation and response.

How does the 0-day global period affect same-day care?

Same-day preoperative and postoperative care is included in the service. An assistant-at-surgery claim requires documented medical necessity; co-surgeon and team-surgery billing are not permitted.

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.
