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 with the short stay outlier (SSO) adjustment.
This amount does not include any other 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.
