Maximizing Your Revenue Under PDGM
Understanding how Medicare calculates your payment is the first step toward maximizing your reimbursement. As explained in this video, Medicare uses a formula based on the patient’s clinical characteristics and other data to place each 30-day period of care into a payment group.
This Patient-Driven Groupings Model (PDGM) formula includes five key categories that impact your payment:
- Admission Source
- Timing
- Clinical Grouping
- Functional Impairment Level
- Comorbidity Adjustment
Accurate coding and classification in each of these categories can significantly affect your revenue. The tools below are designed to help you understand and optimize your PDGM payments.

PDGM Comorbidity Adjustment Tool
Check for comorbidity codes that may increase payment.
Secondary diagnosis codes can affect your plan of care and potentially increase payment by up to 20%. Use this tool to see if your comorbidity qualifies for an adjustment.
