0.268ESRDHCC 112 — Fibrosis of Lung and Other Chronic Lung Disorders
0.000What This Code Means
Acute lung problems that develop shortly after radiation therapy to the chest, such as inflammation or fluid buildup in the lungs.
Coding Tips
- •Document the type of radiation therapy and anatomical site treated
- •Link this diagnosis to the underlying malignancy code and the radiation procedure code for complete documentation
Clinical Significance
Acute radiation pneumonitis develops within 1-6 months after thoracic radiation therapy and represents a significant iatrogenic complication. It is important for risk adjustment in V24 as it captures treatment-related lung injury requiring additional management, corticosteroid therapy, and potentially prolonged respiratory support.
Documentation Requirements
- ✓Documentation of radiation therapy to the chest with dates and dosage
- ✓Temporal relationship between radiation treatment and symptom onset (typically 1-6 months post-radiation)
- ✓Underlying malignancy diagnosis being treated
- ✓Chest imaging showing radiation-related changes (ground-glass opacities in radiation field)
- ✓Pulmonary function test results if available
- ✓Treatment plan including corticosteroids and supportive care
Commonly Confused Codes
J70.1 (Chronic pulmonary manifestations due to radiation) — acute vs. chronic; J70.0 is early-onset, J70.1 is late fibrosisJ84.10 (Pulmonary fibrosis, unspecified) — radiation fibrosis should be coded with J70.1, not generic fibrosis codesJ18.9 (Pneumonia, unspecified) — radiation pneumonitis can mimic infectious pneumonia radiographicallyJ80 (Acute respiratory distress syndrome) — ARDS may develop from severe radiation pneumonitis
