AHA Coding Clinic® for ICD-9 - 1988 Third Quarter
Q & A
In the review of medical records for diagnostic coding accuracy, pneumonias with unspecified bacteria are automatically assigned to code 486, Pneumonia of unspecified organism, even though the physician has attested to a diagnosis of gram-negative pneumonia or probable gram-negative pneumonia when (a) the culture and smear reveal several organisms, none of which can be identified as the causative agent, or (b) either the sputum was not obtainable or sputum reveals no growth or normal flora. In what instance would it be appropriate for the physician to use the diagnosis of gram-negative pneumonia, 482.8, Pneumonia due to other specified bacteria, in the absence of confirmatory cultures? ...

Article Overview
This Q&A article focuses on diagnostic coding for pneumonia when the documented bacterial cause is unclear or only partially supported by laboratory findings. It is relevant to coders, CDI staff, auditors, and physicians who review infection documentation and code assignment for respiratory diagnoses. The discussion centers on how the documentation is interpreted in the context of unspecified versus more specific pneumonia coding guidance.
Why This Topic Matters
Accurate pneumonia coding depends on whether the record supports a specific bacterial etiology or only an unspecified diagnosis. This affects code selection, data quality, and consistency in record review.
