What This Code Means

A secondary form of diabetes that has damaged the blood vessels in the eye, but without swelling in the macula.

Coding Tips

• •This code indicates diabetic retinopathy without macular edema; confirm imaging or ophthalmology findings
• •The fifth character '9' indicates no macular edema; use E13.311 if macular edema is documented

Clinical Significance

E13.319 captures unspecified diabetic retinopathy without macular edema in other specified diabetes mellitus. The absence of macular edema indicates the central retina is not currently affected by fluid accumulation, though the patient still has retinal vascular damage requiring ongoing ophthalmologic surveillance to prevent progression.

Documentation Requirements

• ✓The record must document secondary diabetes with retinopathy confirmed by ophthalmologic examination.
• ✓The absence of macular edema should be stated or implied by imaging findings.
• ✓Providers should be queried to specify the retinopathy stage for more accurate coding.
