Claim Admission Date (FFS)

This variable is contained in the following files:

Home Health Agency (Fee-for-Service) Hospice (Fee-for-Service) Inpatient (Fee-for-Service) Skilled Nursing Facility (Fee-for-Service)

SAS Name

CLM_ADMSN_DT

On an institutional claim, the date the beneficiary was admitted to the hospital, skilled nursing facility, or religious non-medical health care institution, and starting October 2023 this field is added to reflect the admission date for hospice or to a home health agency (HHA).

Comments

The admission date is a required field on inpatient and HHA claims. The Medicare rule is the admission date and the claim “from date” (field called CLM_FROM_DT) must be the same.

From 1/1/2020 until 10/2/2023 there was no direct way to determine the admission date for HHA. Prior to January 2020, when this variable appeared in the HHA it is the date the care began for the HHA services reported on the claim.

The date in this variable may precede the claim from date (CLM_FROM_DT) if this claim is for a beneficiary who has been continuously under care.
