NAME: NCH Beneficiary Part A Coinsurance Liability Amount DESCRIPTION: The amount of money for which the intermediary has determined that the beneficiary is liable for Part A coinsurance on the institutional claim. Under Part A, beneficiaries pay coinsurance starting with the 61st day of an inpatient hospital stay (one daily amount for days 61-90, and a higher daily amount for any days after that, which count towards a beneficiary’s 60 lifetime reserve days) or the 21st day of a skilled nursing facility (SNF) stay (a daily amount for days 21-100, after which SNF coverage ends). This variable is null/missing for home health and hospice claims.
