Star Ratings and VBP Measure Fundamentally Different Things

The most important thing to understand is that star ratings and VBP adjustments evaluate your agency through different lenses. Star ratings reward strong documentation and process compliance. VBP rewards actual patient outcomes measured through claims data and patient experience surveys.

Here is how the two systems compare:

An agency can score well on what clinicians document in OASIS and still underperform on what happens after the visit ends. That is the paradox. Your star rating reflects your best clinicians' documentation. Your VBP adjustment reflects your entire team's real-world impact.

The Three Most Common Gaps Between Stars and VBP

After working with agencies across multiple states, I see the same three gaps creating this disconnect between star rating and VBP performance.

Discharged to Community (DTC) Rates Below National Benchmarks

DTC is one of the highest-weighted VBP measures. It captures whether patients successfully return to community living after a home health episode. Many 4-star agencies have risk-adjusted DTC rates that fall below the national average because their discharge planning is inconsistent across clinicians. One clinician may coordinate beautifully with the patient's physician and family. Another may document the same OASIS items correctly but miss the care coordination steps that actually keep patients home.

Potentially Preventable Hospitalization (PPH) Rates Above Target

PPH measures whether your patients end up back in the hospital for conditions that could have been managed at home. This is a claims-based measure, meaning it tracks what actually happens to your patients regardless of what your OASIS documentation says. An agency can have excellent OASIS scores for symptom management education while still having high PPH rates because the education is not translating into consistent patient behavior change at the bedside.

Patient Satisfaction Stuck at 3 Stars While Quality Hits 4+

HHCAHPS scores contribute to VBP, and many agencies with strong quality stars plateau at 3 stars on patient satisfaction. The "Would Recommend" and "Overall Rating" percentages often hover in the 70s when they need to be in the mid-80s. This usually signals a communication gap, not a care gap. Clinicians are delivering good care but not consistently communicating the plan, educating effectively, or setting expectations in a way patients recognize and value.

Why New Hires Are Your Biggest VBP Risk

Every new clinician you onboard today affects your VBP scores 18 months from now. That is not an exaggeration. It is how the VBP performance-to-payment timeline works. CY 2024 performance determines CY 2026 payment adjustments. CY 2025 performance will determine CY 2027 adjustments.

If a new hire spends their first 60 days learning your systems but not fully absorbing your quality expectations, every patient they see during that window is a data point in your future VBP calculation. Multiply that across 5, 10, or 20 new hires per year, and you have a significant volume of patient encounters being delivered below your established standard.

The agencies that close the star/VBP gap invest in competency-based onboarding that goes beyond orientation checklists. They ensure new clinicians understand not just what to document, but how to execute the specific behaviors that drive outcomes: consistent teach-back methods, standardized care coordination workflows, and real-time clinical decision-making aligned with the agency's protocols.

The 2026 HHVBP Changes Make This More Urgent

CMS is raising the stakes for 2026. Four new measures are being added to the HHVBP measure set:

The MSPB-PAC measure is particularly significant. It captures total Medicare spending, meaning agencies will now be evaluated not just on their own outcomes but on the downstream costs their patients generate. A patient who gets readmitted or visits the ED multiple times increases your MSPB-PAC score regardless of how well you documented your care.

The maximum payment adjustment remains at +/-5%, but benchmarks continue to tighten. We work with agencies in Maryland, an early VBP pilot state. What we have seen is that VBP gains eventually plateau as benchmarks rise because the comparison group improves too. States that are newer to VBP are still in the window where meaningful improvement is possible, but that window is closing with every performance year.

Closing the Gap: From Quality Culture to Consistent Execution

If you are a 4-star agency with a VBP penalty, the good news is that you have already done the hard part. You have built a quality culture. Your team cares. Your processes exist. The fix is not reinventing your approach. It is ensuring every clinician, including the ones you hired last month, executes your standards consistently at point of care.

Three things move the needle:

Standardize clinical behaviors, not just training content. The gap is not in the classroom. It is between the classroom and the patient's living room. Microlearning delivered between visits, in 90-second sessions clinicians can complete before their next appointment, reinforces behaviors when it matters most.

Measure consistency, not just competency. Tracking whether a clinician completed orientation tells you nothing about whether they are executing at your standard 30 days later. Track outcome-level data by clinician cohort (new hires vs. tenured staff) to identify where consistency breaks down.

Act on your data faster. The 18-month lag between performance and payment means you cannot afford to wait for annual quality reviews. Monthly review of DTC, PPH, and HHCAHPS trends, broken down by team and hiring cohort, gives you the visibility to intervene before the data becomes a payment adjustment.

HomeCentris Home Health II used this approach in Maryland, one of the most competitive home health markets in the country. They achieved 4-star quality status in 6 months, with 9 of 11 quality measures improving. The key was not adding more training hours. It was ensuring training translated into consistent execution at every visit.

Key Takeaways

• A high star rating proves your agency has built a quality culture, but VBP measures outcomes your star rating does not capture, particularly claims-based results like hospitalizations and Medicare spending.
• The three most common gaps are DTC rates below benchmark, PPH rates above target, and patient satisfaction stuck at 3 stars despite 4+ quality stars.
• Every new hire affects your VBP scores 18 months later, making competency-based onboarding your highest-leverage investment.
• The 2026 HHVBP changes add four new measures including MSPB-PAC, which tracks total downstream Medicare spending per patient.
• The fix is not more training. It is standardizing execution at point of care so every clinician delivers consistently, every visit.

Frequently Asked Questions

Why does my agency have a high star rating but still get a VBP penalty?

Star ratings and VBP measure different dimensions of quality. Star ratings are primarily driven by OASIS-based documentation metrics and process compliance. VBP evaluates actual patient outcomes through claims data (hospitalizations, ED visits, Medicare spending) and patient experience surveys (HHCAHPS). An agency can excel at documentation while underperforming on the outcomes that documentation is supposed to drive.

How much does a VBP penalty actually cost a home health agency?

The maximum VBP adjustment is +/-5% of Medicare fee-for-service payments. For an agency with 2,000 episodes per year at an average reimbursement of roughly $3,000 per episode, a 2% penalty costs approximately $120,000 annually. That same agency could be earning a 2% bonus instead, making the real gap between penalty and potential bonus roughly $240,000 per year.

When do my current clinical operations affect my VBP payment?

VBP operates on an approximately two-year lag. CY 2024 performance determines CY 2026 payment adjustments. CY 2025 performance determines CY 2027 adjustments. This means clinical decisions your team makes today will show up in payment adjustments roughly 18 to 24 months from now.

What are the new HHVBP measures for 2026?

CMS added four new measures for CY 2026: one claims-based measure (MSPB-PAC, which tracks total Medicare spending per beneficiary in the post-acute care setting) and three OASIS-based functional improvement measures (Improvement in Bathing, Improvement in Upper Body Dressing, and Improvement in Lower Body Dressing). These expand the model's focus on both functional outcomes and cost efficiency.

Can small agencies compete in the HHVBP model?

Yes. CMS uses volume-based cohorts, grouping agencies into smaller-volume and larger-volume categories with separate benchmarks. This means small agencies are compared against other small agencies, not national chains. The key is consistency, not size. A 500-episode agency that executes consistently will outperform a 5,000-episode agency with high clinician variance.
