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?
Select an answer to reveal the explanation.
Short Explanation
Think of the chart like a court case—the attending’s documentation is the sworn testimony. Nursing notes can be useful clues, but they don’t get coded as diagnoses unless a provider owns them. Stick to what the physician or other treating provider actually documented.
Full Explanation
For facility coding, ICD-10-CM diagnosis codes must be supported by provider documentation in the health record. Nursing impressions that are not confirmed or integrated by a treating provider are insufficient for code assignment. Pneumonia and respiratory failure documented by the attending are reportable; an unverified nursing-only aspiration risk is not coded as a diagnosis without provider support or a compliant query when indicated.
