Unit 10 Audit Response Report
[Instructor Name]
[Date]
The hospital, the claims, the reviewer and every amount are composite; the regulations, guidelines and study cited are real.
Executive Summary
Accept, contest, repay, extend. The hospital accepts three denials, in which the record does not support the diagnosis, and will repay $9,975.42. It contests six denials, totaling $23,738.98, in which the record documents the diagnosis together with clinical findings the reviewer did not address. Because the three accepted claims share one documentation pattern, the hospital will review its own claims with the same pattern for the look-back period and will report and return any further overpayments it identifies. A corrective action plan addresses the pattern.
Background
In a composite review, the hospital's Medicare review contractor sampled 25 inpatient claims from the past two years on which acute metabolic encephalopathy was coded as the only major complication or comorbidity. The reviewer denied the diagnosis on nine claims, regrouped each to the lower tier of its family and issued a findings letter. The letter's stated basis is that the documentation did not show "an acute, global disturbance of brain function supported by objective findings." This report responds claim by claim, in the reviewer's order, so it can be read beside the letter.
Findings
The nine denied claims, with the reviewer's dollar difference and the hospital's position:
1. Claim 1, urinary tract infection principal, $3,412.08. Accepted.
2. Claim 2, pneumonia principal, $4,102.66. Contested.
3. Claim 3, cellulitis principal, $3,087.55. Accepted.
4. Claim 4, urinary tract infection principal, $3,668.20. Contested.
5. Claim 5, dehydration principal, $4,455.31. Contested.
6. Claim 6, pneumonia principal, $3,475.79. Accepted.
7. Claim 7, heart failure principal, $3,906.14. Contested.
8. Claim 8, kidney injury principal, $3,812.47. Contested.
9. Claim 9, urinary tract infection principal, $3,794.20. Contested.
The Three Accepted Claims
Claims 1, 3 and 6 share one feature. Encephalopathy appears once, in the discharge summary, written as "acute metabolic encephalopathy, resolved." Earlier notes describe the patient as "confused" or "a bit foggy" on arrival, and nursing assessments record orientation to person and place on the first day. No mental status test is documented, no cause is investigated, and no progress note names the condition while the patient is in the hospital. The official guidelines allow coders to rely on the provider's diagnostic statement, but they also allow a payer to review whether the record supports a diagnosis (National Center for Health Statistics [NCHS], 2025). Here the record does not. Accepting these denials is the accurate decision, and contesting them would weaken the hospital's credibility on the six that deserve a defense.
The three accepted claims were lost not to a strict reviewer but to a diagnosis that appeared for the first time on the day the patient went home.
The Six Contested Claims
Each contested claim rests on documentation already in the record, not on a competing definition of the condition. Claim 2 is representative. The admitting note records "acute confusion, not oriented to time or place, inattentive, CAM positive," and the attending names "acute metabolic encephalopathy due to hyponatremia and infection" on day one. Sodium was 121, corrected over 48 hours with a documented plan, and the progress notes record serial mental status checks until the patient was "CAM negative, at baseline" on day three. The Confusion Assessment Method is a validated bedside tool for detecting acute, global disturbance of attention and thinking (Inouye et al., 1990), which is the very feature the reviewer's letter says was missing. The other five follow the same pattern with different causes. Claim 4 documents a positive assessment, a glucose of 42 and correction with dextrose infusion. Claim 5 records a sodium of 162 and a two-day correction with daily neurologic checks. Claim 7 shows a positive assessment and an ammonia level of 96 in a patient with cirrhosis, treated with lactulose. Claim 8 documents uremia with a blood urea nitrogen of 118 and confusion improving with dialysis. Claim 9 records inattention, a positive assessment and a calcium of 13.8 treated with fluids and calcitonin. In each case the attending names the condition during the stay, identifies a metabolic cause and records the course to resolution. Where the reviewer appears to have applied a stricter clinical definition than the one the hospital adopted, requiring imaging or an electroencephalogram for every case, the report notes the difference but does not rest on it. The argument for each claim is that objective findings were documented and the reviewer did not address them.
Repayment
The three accepted claims total $9,975.42. The hospital will repay this amount through the contractor's offset or refund process. Separately, the hospital's own identification of a pattern starts a duty under the federal overpayment rule: once the look-back finishes quantifying an overpayment, the hospital has 60 days to report it and send the money back (42 C.F.R. § 401.305). The look-back will select every claim in the six-year period on which encephalopathy was the only major complication and first appeared in the discharge summary. The compliance officer will record the date the review begins, the date it ends and the date each overpayment is quantified.
Appeal
The six contested claims go first to the discussion period the contractor offers, with the record excerpts cited above. If the contractor does not reverse the findings there, the hospital will request redetermination, for which the regulation allows 120 days counted from the date the initial determination notice arrives (42 C.F.R. § 405.942). The filing deadlines for this case are tracked by the patient financial services manager.
Corrective Action Plan
1. Discharge summary diagnoses that do not appear in any earlier note will be flagged before final coding, and a query will be sent when the record does not support them. Owner: coding manager. Start: 30 days.
2. Documentation specialists will review every stay with encephalopathy as the only major complication before billing, checking for a mental status test, a named cause and a documented course. Owner: documentation integrity manager. Start: 30 days.
3. Hospitalists will receive a one-page guide on documenting encephalopathy with objective findings, written by the physician advisor. Owner: physician advisor. Start: 60 days.
4. The coding manager will audit 10 encephalopathy claims each quarter for one year and report results to the compliance committee. Owner: coding manager. Start: next quarter.
Conclusion
An external audit is a test of the record, not of the hospital's intentions. Six of the nine claims pass that test on their own documentation, and the hospital should defend them firmly. Three do not, and the hospital should say so plainly, repay them and look for the same pattern elsewhere before anyone else does.

Reading the HI 410 Unit 10 instructions
The final unit usually presents an external auditor's findings on a set of claims and asks you to write the organization's response. Expect to decide, claim by claim, whether to accept or contest each denial, and to support every decision with record evidence. The response typically includes an executive summary, findings in the auditor's order, a repayment section, an appeal section and a corrective plan naming who acts and by when. Many prompts ask you to address what the accepted errors imply for claims outside the sample and how the federal overpayment rule applies. Appeal deadlines and levels should be stated accurately. Cite the regulations for overpayments and appeals, the coding guidelines on documentation and any clinical source behind your rebuttals. The report is written for a compliance committee, so it should be decisive and easy to follow.
How the HI 410 Unit 10 example is put together
A four-word executive summary gives the decision before any detail. A background section restates the reviewer's sample and stated basis for denial. The findings list all nine claims with principal diagnosis, dollar difference and position. The accepted three are explained together: the diagnosis appears only on the day of discharge, with no test, cause or progress note, and the highlighted sentence makes that point directly. A margin note explains why conceding them strengthens the rest. Claim 2 is argued in full as the model rebuttal, with its assessment result, sodium correction and serial checks tied to the reviewer's own criterion, and the other five are summarized by cause. The repayment section explains how the look-back starts the overpayment clock, the appeal section names the discussion period and redetermination, and four corrective actions follow.
Where the points sit in the HI410 Unit 10 rubric
Points on an audit response usually reflect decision quality, evidence, regulatory accuracy, the corrective plan and professional writing. Decision quality carries the heaviest share: graders want each claim accepted or contested for a reason drawn from the record, not a blanket defense. Evidence points reward rebuttals that quote dated findings and answer the auditor's stated criterion. Students lose many points by contesting every denial, which signals poor judgment, or by arguing over definitions instead of documentation. Regulatory points depend on accurate treatment of the overpayment rule, the look-back and appeal deadlines. The corrective plan earns credit when it targets the pattern behind the accepted claims and assigns owners and start dates. An executive summary a committee member can act on, with consistent figures and APA citations, secures the writing points.
Common HI410 Unit 10 mistakes, and how to avoid them
The most common Unit 10 error is defending every denied claim, including those the record cannot support. Another is ignoring what the accepted claims mean for the rest of the population, which leaves the overpayment rule unaddressed. Students often misstate appeal levels or deadlines, or describe the 60-day clock without saying when identification is complete. Rebuttals that cite a different clinical definition instead of documented findings are easier for an auditor to reject. Corrective plans that call for general education without targeting the specific pattern rarely earn full marks. Reports that bury the decision several pages in frustrate a committee reader. If you have your own audit findings to answer, send the auditor's letter or scenario, the claim details and record excerpts provided, and any required report format, and we can write a response that decides each claim on its evidence.

HI410 Unit 10 questions, answered
Where can I find a free HI410 Unit 10 sample paper?
The finished Unit 10 audit response report is here, accepting three encephalopathy denials and contesting six on record evidence.
Should a hospital contest every denied claim?
No. Conceding claims the record cannot support protects credibility. The sample accepts three and repays $9,975.42.
What makes a strong rebuttal to a clinical validation denial?
Dated findings in the record that answer the reviewer's own stated criterion, such as the sample's positive assessment, sodium correction and serial mental status checks.
What does the 60-day overpayment rule require after an audit?
Once the hospital identifies and quantifies an overpayment, including through a look-back, it must report and return it within 60 days.
How long does a hospital have to request redetermination?
The regulation allows 120 days from receipt of the initial determination notice, which the sample's appeal section tracks.
