Home Health’s biggest change in two decades begins January 1, 2020 when CMS will begin using a new Patient-Driven Groupings Model (PDGM) for home health payments. This new system has several key factors:

• Diagnosis driven: The payment rate factors in the patient’s primary and secondary diagnoses. More complex conditions will have a higher payment rate.  
• Primary diagnosis: This describes the primary reason the patient is receiving home health services. The primary ICD-10-CM diagnosis code reported assigns the patient into one of 12 clinical groupings (e.g., neuro rehabilitation, wounds, behavioral health, etc.).
• Secondary diagnosis(es): These comorbid conditions can affect patient care and are also factored into the payment.
• Functional Impairment: The functional impairment of the patient (i.e., low, medium, high) is factored in using eight Outcome and Assessment Information Set (OASIS) items related to Activities of Daily Living (ADL). A higher functional impairment level will qualify for a higher payment rate.
• Reporting period: Care is based on a period of 30 days instead of 60 days.
• Therapy thresholds removed: With the elimination of the therapy caps, this information no longer factors into the payment.
• Low Utilization Payment Adjustment (LUPA) revised: The old system threshold for LUPA was set at five visits during a 60 day period. Under the new system, LUPA is based on the case-mix group (see below) and can range from two to six visits during a 30 day period depending on the group.

Case-Mix Adjusted Payment Group: The following variables are used to calculate the patient’s case-mix adjusted payment group: 

1. Location: geographic location where patient care is provided
2. Admission Source:  institutional (acute or post-acute care provided within 14 days prior to admission) or community (no acute or post-acute care)
3. Timing: early (first 30-day period of care) or late (subsequent 30-day period[s])
4. Clinical Grouping: based on the primary diagnosis
5. Functional Impairment Level: from OASIS items
6. Comorbidity Adjustment: based on the secondary diagnoses

Like the RVU for outpatient services, the weight computed by the case-mix is multiplied by a factor (think conversion factor for RVUs) to arrive at an estimated monthly payment.
