Total PDPM Payment: $0.00

The Patient-Driven Payment Model (PDPM) calculator is a revolutionary tool designed to streamline Medicare payments for skilled nursing facilities (SNFs). Introduced by the Centers for Medicare & Medicaid Services (CMS) on October 1, 2019, the PDPM replaced the older Resource Utilization Groups, Version IV (RUG-IV) system. Unlike its predecessor, which focused on the volume of services provided, the PDPM emphasizes the patient’s condition and care needs to determine Medicare payments. This approach aims to ensure that patients receive personalized, high-quality care tailored to their specific needs.

Purpose and Functionality

The PDPM calculator serves a critical purpose in the healthcare sector by calculating Medicare payments based on the patient’s individual care requirements. It divides the payment determination into five key components:

  1. Physical Therapy (PT)
  2. Occupational Therapy (OT)
  3. Speech-Language Pathology (SLP)
  4. Nursing
  5. Non-Therapy Ancillary (NTA)

Each component’s payment is influenced by Case-Mix Index (CMI) scores, reflecting the patient’s conditions and characteristics. Additionally, a fixed component covers the facility’s overhead costs.


The Patient-Driven Payment Model (PDPM) Calculator for 2023 uses a specific method to figure out how much money skilled nursing facilities (SNFs) should get for taking care of patients under Medicare. Let’s break down this formula into simpler terms:

  1. Start with the Patient: Look at the patient’s health condition, what kind of care they need, and their daily living activities. This includes understanding why they’re in the facility, their ability to move around, their mental state, and any special needs like speech therapy or nutritional support.
  2. Divide Care into Categories: The formula splits the care into five main parts:
    • Physical Therapy (PT)
    • Occupational Therapy (OT)
    • Speech-Language Pathology (SLP)
    • Nursing
    • Non-Therapy Ancillary (NTA), which includes things like medications and special equipment.
  3. Score Each Part: Each of these five parts gets a score based on the patient’s needs. This score is called the Case-Mix Index (CMI), and it changes based on how complex the patient’s care is. More complex care needs result in a higher score.
  4. Calculate Payments for Each Part: For each of the five parts, multiply a base rate of money (which is like a starting point set by Medicare) by the score (CMI) you figured out. If the facility is in an expensive area, you might also adjust this number higher to account for that.
  5. Add It All Up: Finally, add up the money calculated for each of the five parts. This total is what the SNF gets paid for taking care of the patient.

Key Inputs for Calculation

The calculator requires several inputs to accurately compute Medicare payments, including:

  • Patient Diagnosis: The main reason for the SNF stay and other medical conditions.
  • Functional Status: Based on the Section GG Functional Score, which looks at activities of daily living (ADLs).
  • Cognitive Status: Assessed via the Brief Interview for Mental Status (BIMS) score.
  • Swallowing Disorders, Mechanically Altered Diet, and Speech-Related Conditions: Important for the SLP component.
  • Non-Therapy Ancillary Services: Including medication and medical supplies usage.

Step-by-Step Example

Let’s walk through a simplified example:

  1. Determine the Clinical Category: Suppose a patient is admitted for stroke rehabilitation, affecting PT, OT, and SLP components.
  2. Assess the Functional Score: The patient has moderate difficulty with ADLs, scored at 12 out of 24.
  3. Calculate the Component CMIs: Based on our inputs, let’s say the CMIs for PT, OT, and SLP are 1.2, 1.15, and 1.1, respectively.
  4. Adjust for Facility-Specific Factors: If the facility is located in an area with a high cost of living, this might adjust the base rate upward by 10%.
  5. Combine Component Payments: Using a base rate of $100 for simplicity, and applying our CMIs and adjustment factor, we calculate each component’s payment and sum them for the total PDPM payment.

The PDPM calculator represents a significant leap forward in Medicare reimbursement processes, prioritizing patient care needs over the quantity of services rendered. By taking into account a wide range of patient-specific factors, the PDPM ensures that SNFs are adequately compensated for providing high-quality, individualized care. Its application not only simplifies the payment calculation process but also encourages facilities to focus on delivering patient-centered care. With its introduction, the PDPM calculator has become an indispensable tool in the healthcare industry, fostering an environment where patients’ needs drive care decisions and financial reimbursements.
