“We rework a lot of charts.” “The claim goes back and forth.” “Nothing is wrong, but everything takes three passes.” Lean Six Sigma Healthcare: First-Pass Yield and Rolled Throughput Yield, The Hidden Factory Inside Your Revenue Cycle gives those familiar frustrations two useful measures.
First-pass yield (FPY) shows how often work clears a defined step correctly the first time. Rolled throughput yield (RTY) shows the likelihood that work clears every defined step on its first pass. Together, they make rework visible, even when the claim, chart, or authorization eventually gets completed.
Measure first-pass success, not just eventual completion
FPY counts work that meets the acceptance criteria at a specific step without correction, rework, resubmission, or another pass. ASQ describes first-pass yield as a measure of work completed correctly without being rerun, retested, returned, or repaired. Read ASQ’s overview of rolled throughput yield and related process-yield concepts.
For a revenue-cycle team, the unit might be a claim, authorization, or documentation packet. The key is to define both the unit and the gate: for example, “claim accepted by the payer on its initial submission.” A claim corrected and accepted later may count in eventual output, but not in FPY at that gate.
That distinction matters. A final count can look healthy while staff are repeatedly correcting and resubmitting work. FPY adds the missing question: How much passed without extra handling?
Use rolled throughput yield to see the whole journey
A revenue-cycle item often moves through multiple gates. RTY combines first-pass yield across those sequential steps to estimate the chance that an item moves through the defined process without a first-pass failure. ASQ explains RTY as an overall yield measure built from the yields of individual process steps.
Consider three gates with first-pass yields of 96%, 92%, and 95%. Their combined RTY is approximately 84%. Each individual step may appear to perform reasonably well, while the end-to-end likelihood of getting through all three without rework is lower.
That gap helps reveal the hidden factory: the unplanned work that re-enters the process, such as correcting documentation, chasing missing information, resubmitting a claim, or checking its status again. These activities consume staff attention and operating capacity even if the item ultimately reaches completion. The Lean Enterprise Institute’s discussion of rework reinforces the value of addressing process design rather than normalizing repeated correction as routine work.

RTY is not itself a dollar figure, a denial rate, or a forecast of collections. It is a process-yield measure. It helps leaders see where first-pass losses accumulate; additional analysis is needed to understand their labor, cash, and capacity implications.
Define the gates consistently before comparing results
Before comparing FPY or RTY between departments, locations, or time periods, agree on what counts as a unit, what qualifies as a pass, and which steps belong in the process. Keep distinct events distinct: an initial return for correction is not automatically the same as a payer denial, an appeal, or a final write-off.
This is especially important in healthcare, where the work changes around the work. Shift changes, employee movement and turnover, changing patient needs, and medical emergencies can all affect how a process operates. A yield shift may reflect a genuine improvement, or a different mix of work.
If a team changes a process, ask whether the correction actually raised first-pass yield or whether the movement could be ordinary noise. Hypothesis testing can help assess whether a change is supported by evidence; variance testing can help evaluate differences across shifts, locations, providers, or payers. The intent is not to assume every difference has a single cause, but to make comparisons more disciplined.
Connect yield to capacity and financial planning
In Fayetteville, Cape Fear Valley Health announced an emergency department expansion that includes 24 additional pediatric emergency beds and anticipates approximately 123,000 to 124,000 adult and pediatric emergency visits in 2026. That local capacity investment is a reminder that healthcare organizations must plan for changing demands on people and operations. Yield measures offer a different, complementary view: how much existing work moves forward without being sent back through a step.
A low first-pass result does not, by itself, prove that an entire process is failing. It does give leaders a reason to examine where extra touches occur, what capacity those touches occupy, and whether a targeted correction merits testing. As a separate, non-healthcare example, NIST describes a manufacturing improvement project in which first-pass yield rose while processing and lead times declined. That case is not a healthcare benchmark or a promise of similar outcomes; it illustrates why measuring first-pass performance can make improvement opportunities easier to evaluate.

FAQ: FPY, RTY, and revenue-cycle rework
What is the difference between FPY and RTY?
FPY measures whether work passes a specific step correctly the first time. RTY reflects the combined likelihood of passing every defined sequential step without first-pass failure.
Can a claim be completed successfully but still count as an FPY failure?
Yes. If it required correction or resubmission at the gate being measured, it did not pass that gate on the first attempt, even if it was ultimately completed.
Does a lower RTY automatically mean lost revenue?
No. RTY measures process yield, not dollars. It can identify accumulated first-pass losses that leaders may then examine for their operational and financial effects.
PULSESIGMA: A measurement layer for improvement
PULSESIGMA is a current Windows-based application that works alongside exported data from existing systems. It is a measurement layer, not a records system: it does not replace or write to the EHR, practice management, billing, clearinghouse, or payroll systems. It helps organizations ask what a process is costing and whether a correction worked, or whether the observed change may be noise.
Business-level outputs include denial exposure, rework labor cost, lost capacity, recoverable cash, and validated financial benefit. Loaded labor cost can be configured by role, department, and location; estimates are traceable to source data. When a required value is missing, the application reports AWAITING DATA rather than treating a blank as zero. Its supported method is DMAIC: Define, Measure, Analyze, Improve, Control.
PULSESIGMA offers LITE for independent physicians, dentists, and single-location practices; STANDARD for multi-provider organizations with dedicated billing and revenue-cycle teams; and ENTERPRISE for health systems and corporate healthcare entities. The data model carries forward across editions, so organizations do not have to start over as they grow.
