Coding Knowledge and Skills · 120 questions
- A county hospital coder reviews a completed inpatient chart for pneumonia with associated respiratory failure. The attending documents both conditions in the progress notes and discharge summary, while a nursing note alone mentions possible aspiration risk that no provider confirmed. Which approach is correct for diagnosis code assignment?
- An academic medical center outpatient surgery coder reads an operative report describing a completed laparoscopic cholecystectomy. The surgery schedule had been booked as an open cholecystectomy. Which source should drive procedure code assignment?

- A hospital outpatient coder correctly unbundles two distinct procedures under CMS NCCI, but a contracted commercial payer's edit system denies one line as inclusive of the other. What does this scenario illustrate?
- An acute-care hospital discharges a Medicare patient to an inpatient rehabilitation facility (IRF). The HIM director reminds acute-care coders that IRF payment and coding rules differ from IPPS DRG payment. Why does that distinction matter for acute-care coding awareness?
- A commercial payer routinely denies a particular secondary diagnosis that Official Guidelines and the record clearly support. A supervisor tells the coder to stop reporting that code so denials stop. What is the ethical coding action?

- During inpatient coding at a municipal medical center, a legitimate postoperative complication is clearly documented and meets reporting criteria, but quality leadership asks the coder to omit it so complication rates look better. What is the ethically correct action?
- An inpatient coder notices that assigning an undocumented major complication or comorbidity (MCC) would shift the case into a higher-paying MS-DRG. No clinical indicators or provider documentation support the MCC. What should the coder do?
- A supervisor instructs an inpatient coder to change codes in a way that contradicts Official Guidelines and the documentation. What is the most appropriate ethical response?
- A hospital coding manager reviews a query that suggests the only acceptable answer is "acute respiratory failure" when the note is ambiguous. How does this relate to AHIMA Standards of Ethical Coding?
- While abstracting an inpatient stay, a coder is asked to email a neighbor the patient’s coded diagnoses “just to help with insurance questions.” What ethical coding obligation applies?
- A facility continues to apply last year’s ICD-10-CM guideline changes after the effective date of new Official Guidelines, solely to avoid retraining. From an ethical coding perspective, what is the concern?
- A hospital proposes coder incentive pay based solely on increasing average CMI, with no concurrent quality or compliance controls. What ethical risk should leadership recognize?
- A coder discovers a colleague routinely assigning unsupported MCC codes to inflate MS-DRG payments. What does ethical practice expect?
- To hit daily productivity targets, an inpatient coder begins finalizing charts before operative reports and discharge summaries are available, contrary to facility incomplete-record policy. What is the ethical assessment?
- For an acute care inpatient discharge, which UHDDS-aligned definition should the coder use when selecting the principal diagnosis?
- Which statement best reflects UHDDS criteria for reporting “other diagnoses” on an acute inpatient discharge?
- When abstracting hospital discharge data, how should the coder approach procedures under UHDDS concepts?
- An inpatient has multiple procedures. Using UHDDS-oriented logic, which approach best guides principal procedure selection when applicable?
- Why must hospital abstractors report discharge disposition accurately for UHDDS compliance?
- The inpatient record lists remote personal history of childhood asthma with no evaluation, treatment, or monitoring during the current stay. How should this be handled for UHDDS “other diagnoses” reporting?
- A coder applies the inpatient UHDDS principal-diagnosis definition to select the first-listed diagnosis on a hospital outpatient encounter. What is the correct assessment?
- Besides payment, why does accurate designation of principal versus other diagnoses matter under UHDDS?
- When abstracting a newborn inpatient discharge, how should the coder approach UHDDS-oriented data definitions compared with a typical adult admission?
- A quality auditor reviews inpatient abstracts by comparing coded principal diagnosis, other diagnoses, and procedures to UHDDS definitions. What role does UHDDS play in this process?
