This variable indicates whether a beneficiary met the condition criteria for migraine and other chronic headache as of the end of the calendar year.
The condition variable requires beneficiaries to satisfy both claims criteria (a minimum number/type of Medicare claims that have the proper diagnosis codes and occurred within a specified time period) and coverage criteria (Medicare FFS Part A and Part B coverage during the entire specified time period).
For migraine and other chronic headache, beneficiaries must have at least one Medicare inpatient claim or two other non-drug claims of any service type with a related code in any position during the 2-year reference period. When 2 claims are required, they must occur at least one day apart.
