Getting Discharge Function Scores Right: What MDS Coordinators Need to Know

By Sandra Rich, RN | SVP of Clinical Reimbursement, Limitlessli

When used in the right clinical context, incentive spirometry supports respiratory function during recovery while reinforcing disciplined nursing assessment and documentation. When used reflexively or without reassessment, however, it can raise questions about medical necessity and skilled involvement.

And yet, in my years working with SNFs across the country, I’ve seen the same patterns play out again and again. Discharge Function Scores that don’t reflect the resident’s actual functional status at discharge. GG coding that was solid at admission but drifted by the time the discharge assessment was completed. Documentation gaps that made accurate scoring nearly impossible to defend under audit.

Getting this right isn’t just about compliance. It’s about making sure the clinical picture CMS sees matches the care your team actually delivered.

Here’s what I want MDS coordinators to understand about Discharge Function Scores, and where I see the most room for improvement.

Why the Discharge Function Score Carries So Much Weight

The Discharge Function Score measures how independently a resident can perform specific self-care and mobility activities at the time of discharge. It uses GG items that your team captured during Medicare admission and the discharge performance 3-day windows, and it compares the resident’s discharge function to a risk-adjusted expected score based on their admission baseline.

When your facility’s actual discharge scores consistently fall short of the expected scores, it affects your Quality Reporting Program (QRP) outcomes. Starting with the changes CMS has rolled into recent payment rules, it increasingly affects your facility’s reimbursement position. As of the FY 2027 program year, it will show up in SNF VBP calculations.

Years ago, I worked with a group of facilities that could not increase their Short-Stay Five-Star ratings and, worse, could not understand why. They brought me in, and I went to work.

It didn’t take long to see the problem. As I reviewed their QRP Review and Correct Reports, each of their three homes had MDS-based QRP Measure Discharge Function Scores falling in the 30% to 40% range.

So I put my plan into action: close monitoring of their reports, detailed review of section A and the 10 Functional Abilities across the GG Self-Care and Mobility sections, education for the MDS coordinators and interdisciplinary team (IDT) members and establishing the importance of weekly GG meetings.

The results were astonishing. Each home’s percentage steadily climbed into the 85% range over the following quarters, and their star ratings rose to five stars.

Where the Errors Actually Happen

In my experience, Discharge Function Score problems almost never start at discharge. They start earlier in the stay, and they compound.

Here are the patterns I see most often:

Admission GG assessments that don’t reflect true baseline. If the admission GG coding overstates a resident’s independence, every subsequent comparison becomes distorted. The expected discharge score is built off that baseline.

Interdisciplinary teams that aren’t aligned on GG coding. Nursing, therapy, and the MDS coordinator often have slightly different interpretations of what a GG score should reflect. When those interpretations aren’t reconciled during the stay, the discharge assessment ends up being a guess.

Documentation that doesn’t support the score. The GG items require documentation of the resident’s usual performance over the assessment window. When the clinical record doesn’t clearly reflect what the resident was doing functionally, the score becomes vulnerable under any kind of review. More times than I can count, I see GG items coded with the refusal code (07) or non-applicable/not attempted scores (09, 10, 88). When I’ve taken a deep diveinto this across numerous facilities, these codes are all too often being used out of convenience or because the team hasn’t been educated on what these scores actually mean. What I’ve learned from speaking directly with facility teams is that these codes are frequently used just to avoid a dash, without realizing the implications on the overall clinical picture of the resident. For example, nursing documentation may indicate a refusal code while therapy is documenting that the same resident performed willingly and without issue.

These codes should be a priority during your GG IDT facility review, because understanding how imputation works is crucial to the Discharge Function Score calculation. These scores will calculate as dependent (01), which can result in an inaccurate independence level at discharge. Activity not attempted codes should be avoided whenever possible, as the imputation process treats them as incomplete assessments or non-responsive data, and that directly undermines the accuracy of your facility’s discharge outcomes.

What Good Discharge Function Scoring Actually Requires

Accurate Discharge Function Scores come out of facilities that treat GG coding as a clinical process, not a data entry task. That means a few things have to be in place:

A reliable admission GG process. The baseline has to be captured accurately, with input from therapy and nursing, and documented clearly in the medical record. If your admission GG coding is soft, everything downstream is soft.

Ongoing functional communication during the stay. GG isn’t a one-time capture. Residents’ functional status changes throughout the stay, and teams that aren’t communicating about those changes in real time end up reconstructing the functional picture at discharge instead of documenting it as it happens.

Structured weekly GG meetings. This is one of the most impactful changes a facility can make. When therapy, nursing, and the MDS coordinator sit down together on a regular cadence to review GG items, discrepancies surface early. A therapist may be seeing functional gains in mobility that nursing hasn’t documented. Nursing may be observing self-care refusals that therapy isn’t aware of. Without a standing meeting to reconcile those observations, thedischarge GG ends up reflecting whoever documented it last, not what actually happened.

The facilities I’ve worked with that added structured GG discussions into their weekly clinical meetings saw immediate improvements in both documentation alignment and Discharge Function Score accuracy. The ones that skip these meetings consistently struggle to explain their scores under any kind of review.

A discharge assessment process that isn’t rushed. Too often, the discharge GG items are completed under time pressure, sometimes after the resident has already left. The window for accurate functional observation has to be preserved.

Documentation that tells the same story. Nursing notes, therapy notes, and the MDS have to align. When they don’t, and this is where most facilities get into trouble, the discharge score loses its defensibility.

The Questions I Ask Facilities Evaluating Their Discharge Function Score Performance

When I start working with a new SNF partner, there are a handful of questions I always ask:

How is admission of GG captured, and who is involved in determining the score?

Is there a standing GG discussion during weekly IDT or clinical meetings?

Who reviews the discharge GG before it’s submitted, and what does that review actually check for?

How often does the facility reconcile GG coding against the clinical record before the MDS is transmitted?

When there’s a discrepancy between therapy’s functional assessment and nursing observations, how is it resolved?

Who is responsible for monitoring the QRP Review and Correct Reports, and how often? And the QRP Threshold Reports?

Who completes the GG coding in the MDS and where is the Usual Function determination found in the EMR to support?

Does the entire IDT staff sign anything to show a collaborative review or meeting in the event of an audit?

The answers tell me quickly where the vulnerabilities are, and they usually match what the data already shows in their QRP performance.

What MDS Coordinators Can Do This Quarter

If you’re an MDS coordinator reading this and your Discharge Function Score performance isn’t where you want it to be, there are a few things worth doing before the next quarter closes:

Pull your last 10 discharge assessments and review the GG coding against the clinical documentation. Look for gaps, inconsistencies, and scores that don’t have clear support in the record.

Sit down with your therapy team and your director of nursing. Have a direct conversation about how GG is being captured, discussed, and reconciled during the stay. If there isn’t a standing process, that’s the first thing to build.
Review your admission GG process with fresh eyes. If baselines are consistently overstated or inconsistent across residents, that’s where your discharge scores are being set up for trouble.
Don’t wait for a QRP performance report to tell you what your Discharge Function Scores look like. The facilities I work with that perform best on this measure are the ones tracking it in real time, not quarterly.

A Final Thought

The Discharge Function Score is one of those measures where the outcome on paper has to match the outcome in the building. When it doesn’t, the facility pays the price twice: once in QRP performance, and again in the confidence clinicians lose in their own documentation processes.

Getting it right takes a clinical approach, not just a coding approach. And it takes a team that treats GG as part of ongoing care, not a box checked at discharge.

If your facility is working through Discharge Function Score performance and you want to talk through what a stronger process might look like, I’m always open to a conversation.
