My client wants to cancel the enrollment and switch plans. What steps should I take, and how do I help them file a complaint if they want to?
Your steps depend on where the enrollment stands: if the plan has not yet submitted the enrollment transaction to CMS, the client can simply contact the plan and it's handled internally with no CMS submission needed; if the transaction has already been submitted, the plan must file a cancellation transaction with CMS. Filing a formal complaint or grievance is a separate matter — the excerpts here only address the grievance right tied to specific involuntary disenrollment notices, not a general complaint process, so I can't give you the general complaint procedure from what's loaded.
What the rule says
Cancelling before CMS submission:
“Cancellations received by the plan before submission of the enrollment or disenrollment transaction to CMS are processed internally by the plan. The enrollment or disenrollment transaction is not submitted to CMS. A cancellation transaction is not necessary.”
Cancelling after CMS submission:
“If the plan transmitted the enrollment/disenrollment transaction to CMS before it received the valid request for cancellation from the individual, it must submit a cancellation transaction to CMS to cancel the now-void enrollment/disenrollment transaction.”
How a cancellation may be made:
“A plan may accept a cancellation by phone, in writing, or in person.”
“Since a cancellation is not an election, an individual does not need an election period to request a cancellation.”
On complaints: the excerpts mention a grievance right only in the context of specific involuntary disenrollments:
“The final notice of involuntary disenrollment must include an explanation of the enrollee's right to file a grievance under the MA organization's grievance procedures that are required by § 422.564.”
This applies to the CY 2027 enrollment guidance, effective for enrollment requests received on or after January 1, 2027 (and optionally for AEP requests effective January 1, 2027).
The excerpts do not contain a general beneficiary complaint or grievance-filing procedure for voluntary cancellation/enrollment situations; only a grievance-notice requirement tied to specific involuntary disenrollment scenarios was found.
