Medicare Revocations Will Reach Backward in January. A Late Billing Company Update Can Set the Date.

Most physician practices skip the Medicare home health payment rule. This year it holds a change that applies to them. The CY 2027 home health final rule (CMS-1844-F), published in the Federal Register on November 9, 2026, rewrites the effective dates for Medicare enrollment revocations for all provider and supplier types, physicians and group practices included. CMS says its enrollment provisions take effect January 1, 2027.

Until now, some revocations started 30 days after CMS mailed the notice. The practice could keep the money it had already been paid. CMS has removed that forward-looking date. Each revocation ground now has its own effective date, and most of those dates point to the past.

What a backdated revocation does

A revocation ends Medicare billing privileges and generally bars re-enrollment for 1 to 10 years. A backdated effective date adds a second cost. CMS states that retroactive revocations are intended to recoup payments the provider was not entitled to because of the non-compliance. Services furnished after the effective date are exposed.

CMS gave a fair answer to the obvious objection. It says only about 3 percent of providers are ever revoked, and that it often uses milder actions such as stays and deactivations for minor problems. Commenters asked CMS to keep backdating for fraud and other serious misconduct. CMS refused, and wrote: "Non-compliance at any level and to any degree remains non-compliance." A revocation is still unlikely for most practices. If one comes, it can now cost far more.

The change most practices will miss

Under 42 CFR 424.516(d), physicians, non-physician practitioners and their organizations must report a change of ownership, an adverse legal action, or a change, addition or deletion of a practice location within 30 days. All other enrollment changes are due within 90 days.

Before this rule, only the 30-day items carried a backdated revocation. The 90-day items did not. Now they do. Revised 42 CFR 424.535(g)(1)(ix) sets the effective date for every failure to report at the day after the report was due. CMS's own examples of the data that matters are a new managing employee or corporate officer, a new bank, a new billing agency and a new correspondence address.

Here is a hypothetical case. A practice changes billing companies on March 1 and nobody updates the enrollment record. The update is due May 30. If CMS later revokes the enrollment for that failure, the revocation date is May 31, even if the notice arrives a year afterward. The person who could prevent this usually works in the front office and has never heard of 42 CFR 424.535.

Three other changes in the same rule

The rule also changes three things that reach the billing office directly.

• Claims patterns. CMS can already revoke for a pattern of claims that fail Medicare requirements. It has removed the four listed factors it used to weigh, including the percentage of claims denied. CMS says it will still look at the facts of each case. The effective date for this ground is the last date of service on the claims in the pattern.
• False or misleading information. This ground now covers any enrollment-related form or document, including the CMS-588 electronic funds transfer form and opt-out affidavits, whether or not it was certified as true. The effective date is the date the information was submitted.
• Records. Providers must keep orders, certifications, referrals, prescriptions and payment requests for 7 years and give CMS access on request. New language says those records must be accurate, complete and compliant. If a practice does not give access in time, the effective date is the day after the deadline.

Six checks to run before January

This is general information, not legal advice. Talk to health care counsel if you find a problem that goes back more than a few months. A practice can start with these steps:

• Open the PECOS record for the group and for each physician and practitioner. Compare every field with today's facts: legal name, practice locations, owners, managing employees, officers, billing agency, bank and correspondence address.
• List every change in the last 12 months, the date it happened and the date it was reported. Report anything that is still missing now.
• Name one person who owns enrollment updates, and give that person a calendar with the 30-day and 90-day deadlines.
• Add enrollment to the checklist for any office move, suite change, new manager, new bank account or new billing company, so the update starts on the day of the change.
• Send every Medicare or contractor records request to one named person, with the due date written on it. Confirm that your retention policy keeps these records for 7 years.
• Each month, review Medicare denials by reason code. A repeating reason is cheaper to fix now than to explain later.

Your enrollment record is now a billing control

Enrollment updates have always been easy to postpone, because nothing happens on the day one is missed. That has not changed. What has changed is the date Medicare would use if it ever acted. An hour with the PECOS record this month is a small price for knowing it is right. If you want a second set of eyes on what your denials and enrollment gaps are costing, a revenue review can look at one payer and one quarter.
