This variable is the standard payment amount for long-term care hospitals (LTCH) under the Medicare prospective payment system (PPS), which is based on the MS-LTC-DRG.

This amount does not include any applicable outlier payment amount.


Applies only to Inpatient (LTCH) claims. This field is new in October 2015.

For a LTCH PPS claim, only one of four fields will be populated (CLM_SITE_NTRL_PYMT_CST_AMT, CLM_SITE_NTRL_PYMT_IPPS_AMT, CLM_FULL_STD_PYMT_AMT, or CLM_SS_OUTLIER_STD_PYMT_AMT) as they are mutually exclusive (i.e., only one of the 4 fields will have a non-zero value). The field with the non-zero value is included in the Claim Payment Amount field.
