Pneumonia or Bronchitis at Urgent Care
A 34-year-old man presents to an urgent care center with three days of productive cough, fever of 101.8°F, and pleuritic right-sided chest pain. Vital signs: HR 112, RR 22, BP 126/78, SpO2 94% on room air. Examination reveals crackles at the right base and egophony. A chest X-ray is read as “patchy right lower lobe opacity, cannot exclude pneumonia.” The provider documents “acute bronchitis, viral upper respiratory infection, rule out pneumonia” and prescribes azithromycin plus symptomatic care. No pneumonia diagnosis appears in the assessment. The urgent care is owned by the health system and uses the same EHR problem list. The CDI specialist supports the urgent care clinicians and is asked whether this encounter warrants a query, given that the provider has already prescribed an antibiotic and the X-ray is equivocal.
1. Should the CDI specialist query this urgent care encounter? Justify your answer using outpatient coding rules for uncertain diagnoses and the clinical evidence in the record.

Yes, a query is warranted. In outpatient coding, “rule out pneumonia” cannot be coded. The record contains objective evidence that could support pneumonia: fever 101.8°F, tachycardia, tachypnea, hypoxemia at 94%, right basilar crackles, egophony, and a right lower lobe opacity on chest X-ray. The provider also chose azithromycin, which is more consistent with treating pneumonia than with treating uncomplicated viral bronchitis. However, the provider documented acute bronchitis and a viral URI, and the X-ray is equivocal. The CDI specialist should not assume pneumonia; the purpose of the query is to clarify whether the provider is clinically diagnosing pneumonia or treating empirically while the primary diagnosis remains bronchitis. The query is appropriate because the current documentation leaves the principal diagnosis uncertain and because the antibiotic choice and follow-up plan depend on the diagnosis.
2. Draft the query you would send, including the clinical indicators and the impact of clarification on code assignment and risk adjustment.

Query: “The record documents temperature 101.8°F, HR 112, RR 22, SpO2 94% on room air, right basilar crackles and egophony, and a chest X-ray showing patchy right lower lobe opacity read as ‘cannot exclude pneumonia.’ You documented acute bronchitis and viral URI, prescribed azithromycin, and listed ‘rule out pneumonia.’ Please clarify whether you are diagnosing community-acquired pneumonia, acute bronchitis, or another condition. If pneumonia is diagnosed, please document the site (for example, right lower lobe) and any known organism. If pneumonia is not confirmed, please document the clinical basis for treating bronchitis.”
The clarification affects code assignment because “rule out pneumonia” is not codable in the outpatient setting. If pneumonia is confirmed, the principal diagnosis changes and the antibiotic and follow-up plan are better supported. Pneumonia is generally an acute condition and usually has limited HCC impact, so the query should not be framed around risk adjustment. The more important impact is diagnostic accuracy, antibiotic stewardship, and avoiding a claim that is unsupported by the assessment. If the provider confirms bronchitis only, the coder should code bronchitis and not pneumonia.
3. The provider replies, “I treated clinically for pneumonia but the X-ray is not definitive. I will document pneumonia if you think it is appropriate.” How should the CDI specialist respond to avoid coercion and to protect the integrity of the record?
Read the worked answer
The CDI specialist should not accept an invitation to make the diagnosis. The response should be: “I cannot determine the diagnosis; that is your clinical judgment. If you have clinically diagnosed pneumonia based on the fever, tachypnea, hypoxemia, focal crackles, and X-ray opacity, please document pneumonia and your clinical basis. If you are treating empirically but the diagnosis remains bronchitis or uncertain, please document that. The query is for clarification only.” This response avoids “if you think it is appropriate,” which invites the CDI specialist to direct the diagnosis. It also avoids saying “we need pneumonia for the claim.” The specialist should document the query and the response in the record, and should not alter the diagnosis. If the provider documents pneumonia, the coder may code it; if the provider documents bronchitis, the coder must code bronchitis. The integrity of the record depends on the provider making the diagnosis, not the CDI specialist.
