Oth diab with severe nonp rtnop with macular edema, r eye

This code signifies a diagnosis of diabetes mellitus, other specified types, complicated by severe nonproliferative diabetic retinopathy affecting the right eye. Crucially, it also indicates the presence of macular edema, a swelling of the macula, which is a critical part of the retina responsible for sharp, central vision.

This code is appropriate when a patient with a documented "other specified" type of diabetes mellitus (e.g., secondary diabetes, drug-induced diabetes) presents with severe nonproliferative diabetic retinopathy in their right eye, and ophthalmic examination confirms macular edema. Documentation should explicitly state the type of diabetes, the severity of retinopathy, and the presence and laterality of macular edema.

• Ensure the documentation clearly distinguishes "other specified" diabetes from Type 1 or Type 2 diabetes, as different codes exist for those types.
• Verify that the retinopathy is specifically documented as "severe nonproliferative" and not moderate or mild, and confirm the right eye is affected.
• Always code the underlying diabetes first, followed by this retinopathy complication code.
