An individual (or proper applicant) must file an application to be entitled under
the deemed insured provision. Except as provided in this section, the regular rules
on applications apply (e.g., who may file, what constitutes an application).
The HCFA-18-F5 (Application for Hospital Insurance Entitlement) is the application
specifically designed for establishing deemed insured entitlement. However, all retirement
age applications which will be disallowed because the individual is not eligible for
such benefits may serve as an application for deemed insured HI.
NOTE: The HCFA-18-F5 is also an application for monthly RSI benefits.
