Section GG Self-Care and Mobility
Section GG self-care and mobility refers to the two core item sets within OASIS Section GG: GG0130, which scores self-care activities such as eating, oral hygiene, bathing, and dressing, and GG0170, which scores mobility activities from rolling in bed through walking distances and negotiating steps. Together they produce the standardized functional profile used in home health quality measurement.
What GG0130 self-care covers
GG0130 scores discrete self-care activities rather than broad ADL categories. The set includes eating, oral hygiene, toileting hygiene, showering or bathing, upper body dressing, lower body dressing, and putting on and taking off footwear. Each activity gets its own score on the 6-level GG assistance scale, from 06 (independent) down to 01 (dependent), or a not-attempted code. The granularity is the point: a patient may dress their upper body independently but need substantial assistance with lower body dressing and footwear, and the item structure captures that distinction where a single dressing question would not.
What GG0170 mobility covers
GG0170 walks up a functional ladder. Bed mobility items cover rolling left and right, moving from sitting to lying, and lying to sitting on the side of the bed. Transfer items cover sit to stand, chair or bed-to-chair transfer, and toilet transfer. Ambulation items score walking 10 feet, 50 feet with two turns, and 150 feet, plus walking on uneven surfaces, stepping over a curb or single step, and negotiating stairs. Wheelchair items apply to patients who use one. The progression lets clinicians document exactly where function breaks down, which is also where therapy goals belong.
How these items become quality measures
Admission performance on GG0130 and GG0170, compared with discharge performance and risk-adjusted expectations, feeds function measures in the Home Health Quality Reporting Program, including discharge function scoring. Function measures built on OASIS data also count in the expanded HHVBP model, where OASIS-based measures are 40% of the Total Performance Score for CY2026, including new bathing and dressing measures. In plain terms: how carefully your clinicians score a toilet transfer at admission and discharge shows up later in star ratings, HHVBP payment adjustments, and what referral sources see.
Field tips for scoring self-care and mobility
A few habits produce defensible scores:
- Observe the activity when safe rather than relying on patient or caregiver report
- Score the assistance actually needed, not what equipment or willpower might allow
- Use usual performance over the assessment period, not the best single attempt
- Apply not-attempted codes by their definitions instead of guessing a score
- Align GG scores, M1800-series answers, therapy evaluations, and the visit narrative
Frequently asked questions
Are GG0130 and GG0170 collected at every OASIS time point?
They are collected at the major assessment points, including start of care, resumption of care, and discharge, which is what enables admission-to-discharge function comparison. Follow the current OASIS version's item set for exactly which items appear at which time points.
How do Section GG items differ from ADL items like M1810 or M1860?
They cover overlapping activities but use different scales and conventions. M1800-series items score ability with item-specific responses and feed PDGM's functional impairment level. GG items score needed assistance on a uniform 6-level scale and feed quality measures. Both must be answered, and they should tell one coherent story.
Should therapists or nurses score Section GG?
Whichever qualified clinician completes the assessment scores it, and only one clinician completes the OASIS. That said, therapy input on mobility items strengthens accuracy, and many agencies coordinate so the assessing clinician has therapy evaluation findings before finalizing.
