0.000What This Code Means
Lung inflammation caused by medications or drugs, but the specific type or duration of the condition is not clearly specified.
Coding Tips
- •Use this code only when the chronicity (acute vs. chronic) cannot be determined from the medical record
- •Document the causative drug whenever possible to support more specific coding in the future
Clinical Significance
Unspecified drug-induced interstitial lung disease indicates that a medication has caused lung damage but the chronicity (acute vs. chronic) is not clearly documented. This code should prompt provider queries to determine the specific presentation for both clinical management and more accurate risk adjustment coding.
Documentation Requirements
- ✓Documentation of interstitial lung disease attributed to a medication
- ✓Identification of the causative drug when possible
- ✓Clinical presentation and imaging findings
- ✓Provider attestation of drug causation
- ✓Adverse effect coding using T36-T50 codes
- ✓Plans for further characterization of the disease as acute or chronic
Excludes 1 — Do NOT code together
