What This Code Means

Diabetes caused by medications or chemicals with eye damage (retinopathy) of unspecified type that includes swelling in the macula (central vision area).

Coding Tips

• •Confirm with provider whether the retinopathy type is truly unspecified or if it can be more specifically classified
• •The presence of macular edema indicates more advanced eye disease requiring close monitoring

Clinical Significance

Drug or chemical induced diabetes mellitus with unspecified diabetic retinopathy with macular edema represents drug-induced diabetes that has caused retinal damage with fluid accumulation in the macula, the area responsible for central vision. Macular edema is a vision-threatening complication that may require anti-VEGF injections, laser treatment, or corticosteroid therapy. The 'unspecified' retinopathy designation indicates the severity stage (nonproliferative vs. proliferative) has not been documented.

Documentation Requirements

• ✓The causative drug or chemical must be identified.
• ✓Ophthalmologic examination findings should document the presence of macular edema with optical coherence tomography or fluorescein angiography results.
• ✓The provider should specify the retinopathy stage (mild/moderate/severe nonproliferative or proliferative) to allow more specific code selection.
• ✓Laterality should also be documented.
