Section GG Coding Fraud: When the Code Stops Matching the Care

Section GG coding fraud involves knowingly reporting unsupported self-care or mobility performance to increase a skilled nursing facility’s Medicare payment. For the nurse, therapist or MDS coordinator who assessed the resident, the concern is concrete: the code submitted for payment describes help the resident never needed. Medicare pays for the inflated account, diverting health care dollars from the needs the program serves. The useful trail connects what staff observed, who changed the assessment and what Medicare paid for the changed account.

A whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers.

What Section GG Measures

Section GG records a resident’s usual ability to perform self-care and mobility activities, including the help needed to complete them. The activity matters. Toileting hygiene covers clothing management and cleansing. Toilet transfer covers getting on and off the toilet or bedside commode. A resident can need different amounts of help with each.

The Centers for Medicare & Medicaid Services’ assessment manual issued in October 2025 calls for direct observation, incorporating the resident’s own report and documented reports from qualified clinicians, care staff or family. CMS expects an interdisciplinary team to participate. The nurse coordinating the MDS is bringing those observations together. The form does not replace them.

For a Medicare Part A admission, the functional assessment covers the first three calendar days of the Part A stay. It captures the admission baseline before the resident benefits from treatment. The five-day assessment sets the payment rate for the stay unless the facility completes an Interim Payment Assessment. That interim assessment changes payment from its assessment reference date onward. The Part A discharge assessment serves quality reporting, rather than setting the daily payment rate.

A changed admission score can therefore affect more than one day’s bill. Its support belongs in the admission assessment period, even if the resident later improves.

Does a Lower Section GG Score Always Increase PDPM Reimbursement?

No. The payment effect depends on the item, its conversion into function points, the component’s classification rules and the resulting payment group. Adding up the raw codes misses how Medicare calculates the score.

The Patient Driven Payment Model combines physical therapy, occupational therapy, speech-language pathology, nursing, nontherapy ancillary services and a non-case-mix component. Section GG supplies functional inputs to physical therapy, occupational therapy and nursing. Each has its own place in the payment calculation.

For the specified function items, independent and setup assistance both receive four payment points. Supervision receives three, partial assistance two and substantial assistance one. Dependent, activity-not-attempted and missing responses receive zero.

The observation behind a dependent code matters. CMS includes a resident who requires two helpers to complete an activity safely, even when the second helper provides standby assistance only. The activity-not-attempted codes apply only when neither the resident nor a helper performed the activity. Both categories receive zero function points, but they describe different circumstances that the clinical record needs to support.

The physical therapy and occupational therapy function scores range from zero to 24. They include eating, oral hygiene, toileting hygiene, bed mobility, transfers and walking, with averages for the bed-mobility, transfer and walking items before the final sum is rounded. The nursing function score ranges from zero to 16. It uses eating, toileting hygiene, bed mobility and transfers, leaving out oral hygiene and walking.

That difference matters when someone says a revised walking score increased nursing reimbursement. Walking enters the physical therapy and occupational therapy function calculation. We trace the disputed item through the component it actually affects, then compare the original and revised payment groups. The final HIPPS classification connects those groups to the claim.

When Section GG Usual Performance Differs From Nursing and Therapy Notes

When Section GG usual performance differs from nursing and therapy notes, the assessment-period observations and the explanation for the final code become central. CMS directs assessors to record usual performance across the relevant circumstances, rather than selecting the resident’s best or worst episode.

A resident’s function can vary across locations and situations. Nursing, therapy and care staff may therefore contribute different observations. Clinical judgment brings those observations into a supported account of usual performance. We examine which activity each note describes, when it occurred, the assistance actually provided and how the assessor reconciled the differences.

The distinction between collecting an observation and determining the final code matters here. A treatment note describes what happened during that encounter. The assessment draws on the relevant observations across its window. Choosing the episode that produces a desired score reverses that process: the payment target starts deciding which observation counts.

For an insider, the strongest account connects the unsupported code with the decision behind it. Who wanted a different assistance level? What clinical information supported the revision? What happened when staff pointed to their original observations? Those questions connect the clinical record to the facility’s knowledge and its claim for payment.

When MDS Section GG Changed After the Interdisciplinary Team Assessment

If MDS Section GG changed after interdisciplinary team assessment, the original and revised versions show what moved. Contributor records, the reason for the revision and the resulting HIPPS classification show who stood behind it and whether it reached the bill.

Diversicare agreed to a $9.5 million settlement in 2020 over allegations including unnecessary therapy, inflated dependency scores and improper physician certifications. A whistleblower complaint alleged that staff repeated assessments until management obtained the dependency score it wanted under the former Resource Utilization Group payment system:

The allegation puts management’s preferred score ahead of the recorded assessment. For a Section GG concern, we look for that decision in the version history and the instructions staff received, then follow the changed input through PDPM’s own scoring rules.

What Historical RUG Cases Teach About Current PDPM Coding

Historical RUG cases show how payment targets can shape an assessment window. PDPM replaced RUG-IV for covered Medicare Part A stays on October 1, 2019, moving the classification emphasis from therapy-minute groups to resident characteristics and clinical needs.

Life Care Centers of America agreed to a $145 million settlement in 2016 over allegations that it billed for unnecessary therapy and prolonged stays to maximize payment. In its complaint, the government alleged that a rehabilitation manager overruled the MDS coordinator to select the most profitable assessment dates:

The government also alleged that therapy increased during assessment periods and fell afterward without clinical justification. In the government’s telling, the assessment window had become a revenue opportunity.

The current payment inquiry follows the functional observation into the Section GG item, the component score and the paid classification. The historical parallel is the pressure to make an assessment serve a financial target. The calculation has to follow the payment model governing the stay.

What the Pinnacle Audit Shows About the Payment Connection

The HHS Office of Inspector General’s November 2025 Pinnacle audit found that medical records did not support the assigned HIPPS codes in 95 of 100 sampled claims. The findings covered several payment components. Pinnacle disputed the findings.

One example compared an MDS account of a need for daily skilled services for bed mobility and wheelchair training with medical notes describing independent ambulation. The Inspector General concluded that the documentation did not justify the skilled services. That example concerned the need for skilled care. Other findings concerned the payment group assigned to the resident.

Those are distinct payment questions. The first asks what care the clinical record supports. The second asks whether the assessment supports the classification billed. A Section GG inquiry needs that same precision: which activity, which assessment, which component and which claim.

What Are the Documentation Requirements for Skilled Nursing Facilities?

The clinical record must support the resident’s condition, skilled need, services and assessment inputs used for the claim, together with the applicable orders and certifications. For Section GG, the underlying observations, assessment dates and contributor records explain how the facility arrived at its functional account.

A registered nurse conducts or coordinates the assessment and certifies completion. Each contributor certifies the accuracy of the portion completed. Nursing and therapy notes, care-staff observations and the original and revised MDS versions let us examine both the clinical support and responsibility for a changed code.

The billing record completes the comparison. The assessment supplies the HIPPS classification used on the bill, and CMS validation can return a corrected code. The submitted claim and payment record show which classification actually reached Medicare. We connect those records with the insider’s knowledge of how the decision was made.
