PDGM Documentation Strategies for Home Health Agencies

Understanding PDGM’s Impact on Documentation

The Patient-Driven Groupings Model (PDGM) fundamentally changed how home health agencies are reimbursed. Under PDGM, payment is determined by clinical grouping, functional level, comorbidity adjustment, and admission source — all of which depend on accurate documentation.

This shift made documentation quality a direct driver of financial performance.

Clinical Grouping and Documentation

Clinical groupings under PDGM are determined by the primary diagnosis code. This means the principal diagnosis must be accurately identified and coded, supported by comprehensive clinical documentation.

Clinicians should clearly document the primary reason for home health services, the clinical findings that support the diagnosis, and the skilled interventions required to address the condition.

Functional Level Documentation

Functional assessment under PDGM is derived from OASIS items. Accurate functional documentation requires clinicians to assess and document the patient’s actual performance, not just their potential or capacity.

Document specific functional limitations, the level of assistance required, and how functional status affects the patient’s ability to manage their care at home.

Comorbidity Adjustment Documentation

PDGM provides comorbidity adjustments when patients have certain secondary diagnoses. To capture these adjustments appropriately, all relevant comorbidities must be documented and coded.

Ensure clinical documentation supports each secondary diagnosis with relevant clinical findings, treatment, and management plans.

Technology’s Role in PDGM Success

AI-powered documentation tools can help agencies maximize appropriate PDGM reimbursement by ensuring comprehensive capture of clinical information that drives classification. From OASIS accuracy to coding specificity, technology supports the documentation quality that PDGM demands.

Looking Ahead

As CMS continues to refine PDGM, documentation requirements will evolve. Agencies that invest in documentation quality today — through training, process improvement, and technology — will be best positioned to adapt to future changes.
