What is PDPM? Understanding the Patient Driven Payment Model

The Patient Driven Payment Model (PDPM) significantly changed how skilled nursing facilities (SNFs) receive reimbursements from Medicare, shifting away from volume-based payments towards a value-driven approach that emphasizes patient-specific characteristics.

For administrators, clinicians, and financial staff at SNFs, understanding PDPM is crucial for maintaining compliance, ensuring financial viability, and delivering optimal patient care.

This guide provides an in-depth exploration of PDPM, highlighting its components, calculation methods, clinical implications, and practical strategies for implementation.

What is PDPM?

Introduced by the Centers for Medicare and Medicaid Services (CMS) in October 2019, PDPM replaced the Resource Utilization Group, Version IV (RUG-IV). Under RUG-IV, reimbursement was heavily dependent on therapy minutes provided, often leading facilities to deliver excessive therapy without necessarily improving patient outcomes. Some SNFs even went as far as blatantly booking group sessions for patients without intimation, leading to more minutes billed!

The Patient Driven Payment Model shifts this pattern by basing payments on clinical characteristics and anticipated resource needs, thus promoting individualized, patient-centered (and ultimately more transparent) care.

Core Components of PDPM

PDPM calculates reimbursement rates based on five main components, each addressing different aspects of patient care:

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

Additionally, there's a variable per diem adjustment factor influencing reimbursement rates over the length of the patient's stay.

1. Physical Therapy (PT) and Occupational Therapy (OT)

PT and OT components evaluate patients based on two primary factors:

• Clinical category derived from the primary diagnosis.
• Functional status using Section GG of the Minimum Data Set (MDS).

Clinical categories range from orthopedic surgeries to medically complex conditions. Section GG assesses functional ability, rating patients' independence levels in daily activities such as eating, bathing, and transferring.

2. Speech-Language Pathology (SLP)

SLP reimbursement considers:

• Cognitive impairments.
• Swallowing disorders.
• Speech-language comorbidities.

These factors significantly affect the reimbursement rate, reflecting the complexity and resource intensity required for SLP interventions.

3. Nursing

The Nursing component categorizes patients based on clinical conditions, special care needs, and extensive services (such as tracheostomy care or isolation). Accurate coding in Section I (diagnosis), Section K (nutritional status), and Section O (special treatments) of the MDS is essential for proper categorization.

4. Non-Therapy Ancillary (NTA)

NTA accounts for medication and other ancillary services not captured by therapy or nursing components. Conditions such as HIV/AIDS, diabetes mellitus, and wound infections significantly impact the NTA score.

These are also the toughest and most valuable indicators to find, since they are described both in diagnoses as well as treatments.

Variable Per Diem Adjustment

PDPM incorporates adjustments that decrease reimbursement over time for PT, OT, and NTA components, reflecting diminishing resource needs. The PT and OT rates decrease at day 21, while the NTA rate is front-loaded, with higher reimbursement during the first three days of admission.

How is PDPM Reimbursement Calculated?

PDPM reimbursement involves several sequential steps:

1. Classify Patients into Clinical Categories: Using primary diagnosis codes, patients are assigned categories like major joint replacement or acute neurological.
2. Assess Functional Scores: Section GG scores determine patient independence levels. Lower scores represent greater dependency and typically result in higher reimbursement.
3. Calculate Component Scores: Each component (PT, OT, SLP, Nursing, NTA) generates individual case-mix scores based on clinical and functional assessments.
4. Combine Scores to Determine Daily Rate: The total daily rate is calculated by summing the individual component scores and applying per diem adjustments.

Clinical and Operational Implications of PDPM

PDPM fundamentally changes operational strategies at SNFs:

Clinical Documentation

Robust and accurate documentation is essential to ensure appropriate reimbursement. Comprehensive assessments upon admission and throughout a patient's stay are critical.

Interdisciplinary Collaboration

PDPM necessitates increased collaboration among therapists, nurses, dieticians, and social workers. Integrated care planning ensures accurate identification of patient conditions and optimized care delivery.

Resource Allocation

Facilities must balance the provision of necessary services against financial sustainability, particularly monitoring the intensity and duration of therapy services.

Common Challenges with PDPM Implementation

Implementing PDPM presents multiple challenges for SNFs:

• Accurate Patient Classification: Misclassification can lead to significant financial losses or compliance issues. Staff training and regular audits are vital.
• Managing Variable Per Diem Rates: Predicting and managing resources, especially with decreasing reimbursement rates, can be complex.
• Clinical Accuracy: Ensuring documentation aligns with patient conditions requires continuous vigilance and staff education.

Best Practices for Successful PDPM Management

SNFs can adopt several best practices to thrive under PDPM:

1. Regular Staff Training: Continuous education ensures accuracy in MDS completion and enhances interdisciplinary understanding of PDPM.
2. Comprehensive Initial Assessments: Detailed and precise patient evaluations upon admission guarantee appropriate classification and reimbursement.
3. Utilizing Technology and AI Tools: Advanced AI-driven solutions, such as Nanonets Health, streamline the extraction of clinical data from medical records, minimizing manual errors and enhancing efficiency.
4. Periodic Auditing: Regular audits of MDS accuracy and clinical documentation ensure compliance and mitigate financial risks.
5. Interdisciplinary Care Meetings: Regular meetings facilitate collaboration among clinical and administrative staff, ensuring all aspects of PDPM are effectively managed.

The Role of Technology in Optimizing PDPM Outcomes

Technology solutions significantly simplify PDPM compliance and reimbursement accuracy:

• AI-driven Data Extraction and Insights: Tools like Nanonets Health leverage artificial intelligence to accurately capture clinical data from patient records, enhancing MDS item code accuracy and maximizing reimbursement.
• Predictive Analytics: Analytics solutions forecast resource utilization and reimbursement trends, enabling proactive management and planning.
• Automated Coding and Documentation: Automation ensures timely and accurate coding, aligning clinical documentation with PDPM requirements.

Future Trends and Considerations

The landscape of skilled nursing continues to evolve with PDPM. Facilities must remain adaptive, staying informed about regulatory updates and emerging technologies. Ongoing training and investment in innovative solutions will ensure SNFs remain compliant and financially healthy.

Conclusion

PDPM represents a significant shift in Medicare reimbursement philosophy, prioritizing patient-centric care and accurate clinical documentation. Skilled nursing facilities that embrace comprehensive training, interdisciplinary collaboration, and advanced technological solutions will navigate PDPM successfully, optimizing patient care and financial performance. Understanding and effectively implementing PDPM is essential for SNFs to maintain compliance, enhance patient outcomes, and achieve long-term sustainability.
