What This Code Means

Type 1 diabetes with retinal damage from diabetes without swelling in the macula, affecting peripheral or general retinal function.

Coding Tips

• •Confirm documentation explicitly states absence of macular edema
• •This represents unspecified retinopathy severity without the more serious macular complication

Clinical Significance

Type 1 diabetes mellitus with unspecified diabetic retinopathy without macular edema indicates retinal damage from Type 1 diabetes that has not been staged but does not involve macular fluid accumulation. While less immediately vision-threatening than cases with macular edema, any retinopathy signals ongoing microvascular damage and the need for regular ophthalmologic surveillance. Progression to proliferative retinopathy with neovascularization remains a risk requiring monitoring.

Documentation Requirements

• ✓Type 1 diabetes and retinopathy must be documented with ophthalmologic examination findings.
• ✓The absence of macular edema should be confirmed.
• ✓The provider should be queried to specify retinopathy severity (nonproliferative mild/moderate/severe or proliferative) when possible.
• ✓Visual acuity and fundoscopic examination findings should be included.
