Section GG
The OASIS section that scores a patient's self-care and mobility — both current ability and the level of assistance needed.
Definition
Section GG is the standardized OASIS assessment section that measures a patient's functional abilities in self-care (such as eating, oral hygiene, toileting, and dressing) and mobility (such as bed mobility, transfers, and walking). Each item captures the patient's usual performance and the amount of assistance required, coded on a standardized 6-point scale.
Why it matters
Section GG scores drive functional impairment levels under PDGM case-mix and are a frequent target of ADR review, so inconsistent or unsupported GG coding can lead to payment adjustments and denials.

What Is OASIS-E? The Complete Guide for Home Health Agencies (2026)
OASIS-E is the CMS-required standardized assessment behind home health reimbursement, quality, and compliance. This complete guide covers what OASIS-E is, how it differs from D1/E1/E2, the five assessment time points, Section GG, PDGM impact, and documentation best practices.

OASIS-E1 vs OASIS-E2: A Complete Side-by-Side Comparison for Home Health Agencies
Wondering what changed between OASIS-E1 and OASIS-E2? OASIS-E2 is an incremental update, not a redesign. The framework, five time points, and PDGM methodology stay the same, while CMS refines Section GG, cognitive and behavioral items, SDOH, and SPADEs. This guide compares both versions side by side and gives you a transition plan and checklist.

Common OASIS Documentation Mistakes That Lead to Payment Delays
Common OASIS documentation mistakes, such as incomplete assessments, incorrect diagnosis coding, inaccurate Section GG scoring, medication and homebound-status errors, weak skilled-need documentation, and missing physician signatures, are among the biggest causes of home health payment delays. Because OASIS data drives PDGM reimbursement, most of these errors are preventable with point-of-care charting, strong QA, and AI-powered documentation validation.

PDGM Documentation Strategies for Home Health Agencies
Under PDGM, documentation establishes the clinical picture that supports classification, medical necessity, coding, and payment. This guide breaks down 15 PDGM documentation strategies, a documentation-to-payment framework, weak-vs-strong examples, and a closed-loop workflow to keep charts consistent and audit-ready.

Why Medicare Home Health Claims Get Denied
Medicare home health claim denials are revenue leaks, not just billing issues. This guide breaks down the ten most common reasons claims get denied, from OASIS gaps and late NOAs to coding and medical-necessity problems, and how to prevent them to get paid faster.
