C. Period covered by election
An individual may elect not to use reserve days for only one period of consecutive days in each hospital stay. If an election not to use reserve days is made effective with the first day for which they are available, it may be terminated at any time. After termination of the election, all hospital days would be covered to the extent that reserve days are available. (Thus, an individual who has private insurance which covers hospitalization beginning with the first day after 90 days of benefits have been exhausted may terminate their election as of the first day not covered by the insurance plan.) If an election not to use reserve days is made effective beginning with any day after the first day for which reserve days are available, it must remain in effect until the end of that stay unless the entire election is revoked in accordance with E. below.
