What is WiSER and how WoundScribe can help
compliance
CMS WISeR moves Medicare Part B scrutiny to before payment in six states starting January 2026 — here's how it works and how WoundScribe prepares your clinic.
Starting January 2026, CMS is running a six-year demonstration called WISeR — Wasteful and Inappropriate Service Reduction — in New Jersey, Ohio, Oklahoma, Texas, Arizona, and Washington. It uses AI screening plus licensed clinician review to confirm selected Medicare Part B services are appropriate before payment. Coverage rules haven't changed. The timing has.
What's actually under review
Three anchor service categories are in scope, and CMS can add more:
- Skin and tissue substitutes for chronic wounds
- Electrical nerve stimulator implants
- Knee arthroscopy for osteoarthritis
For wound and podiatry clinics, skin substitutes are where WISeR bites hardest. Reviewers expect a qualifying diagnosis, documented conservative care, serial measurements, correct product and units, and patient-specific medical necessity. See our take on skin substitutes after the 2026 CMS rule.
How the two pathways work
You either submit prior authorization first and get a decision in days, or skip it and have your claim auto-routed to pre-payment review. The review is unavoidable — only the timing is your choice. Standard decisions return within three business days, expedited within two. A non-affirmation is usually a documentation gap, not a coverage problem, and most are resolved by resubmission.
Where WoundScribe carries the load
WISeR is a documentation test. Templated notes that could describe any patient are the number-one reason good care gets rejected. Specifics like "DFU right plantar, 3.2 by 2.1 cm" earn affirmations. That's exactly what WoundScribe builds — patient-specific rationale through AI-powered wound imaging, an AI scribe for wound care that maps notes to coverage criteria, and formatting for all six CMS-selected reviewers. Sustain roughly 90% affirmation across ten requests and quarterly reviews can waive prior authorization entirely under Gold Card.
