Field Office (FO) 872 in Kalispell, Montana is responsible for developing proof of
            presence in Lincoln County, Montana.
         
         A claimant states on the application for EHH Medicare, “I was present at least a total
            of 6 months in Lincoln County, Montana, from MM/CCYY to MM/CCYY.” If the claimant
            cannot make this statement, enter the appropriate statement based on the claimant's
            allegation.
         
         The claimant must provide evidence to prove the claimant meets the presence requirement
            for EHH Medicare. The evidence does not have to document every month in the 6-month
            period, but it must support the period in which the claimant can meet the presence
            requirement. Identifying the period(s) of presence that meets the presence requirement
            and acceptable evidence requires discussion with the claimant and guidance from the
            interviewer.
         
         Primary evidence is preferred and considered convincing. For additional information
            on primary evidence, see HI 00803.040C in this section. Since the claimant must establish presence 10 or more years in the
            past, it may be difficult to obtain primary evidence. If primary evidence is unavailable,
            the CR must develop secondary evidence and prepare a special determination.
         
         NOTE: A single document (e.g., anCMS-10902 (EHH Checklist) from the Center for Asbestos
            Related Disease (CARD)) may provide evidence of both presence and diagnosis.
         
         To store evidence, follow instructions in GN 00301.286, Electronic Evidence Documentation and Retention.
