Revocations and Cancelled Elections

(Rev. 2654, Issued: 02-08-13, Effective: 05-09-13, Implementation, 05-09-13)

The Medicare contractor with RNHCI specialty workload submits all RNHCI election,

revocations and cancelled elections to CWF for approval. The CWF will notify the

contractor that these transactions were received and accepted. The CWF uses these

records to maintain a beneficiary file of all RNHCI beneficiary elections and revocations.

This file is used in processing claims for RNHCI services (see section 170.3 below) and

for other Medicare services (see section 180).

CWF rejects any notices of revocations or cancellations when:

• CWF history shows no RNHCI elections are on file;

• The submitted dates do not match the elections on file;

• The revocation date is prior to the date of the election;

• The election in question has already been revoked or cancelled; or

• CWF history indicates an RNHCI claim has been processed during the

election period to which the revocation or cancellation applies. If these

claims were submitted in error, the RNHCI must cancel the claims prior to

resubmitting the revocation or cancellation.
