CASE STUDY - A lung abscess with foul sputum; Which ICD-10-CM code corresponds to the lung abscess diagnosis?

• A. J85.1
• B. J40
• C. J18.9
• D. J85.0

Answer: (D)

When coding this case, the focus is on identifying the exact diagnosis present. A lung abscess is coded with J85.0 when there is no accompanying pneumonia. The description notes a lung abscess with foul sputum, which points to the abscess itself rather than to pneumonia. Therefore J85.0 accurately represents the diagnosis. If pneumonia were documented alongside the abscess, the appropriate code would be J85.1 (lung abscess with pneumonia). The other options describe different conditions—bronchitis (J40) or pneumonia without mention of an abscess (J18.9)—and do not match the documented diagnosis.
