Type 1 diab with severe nonp rtnop with macular edema, bi

This code describes a patient with Type 1 diabetes who has developed severe nonproliferative diabetic retinopathy affecting both eyes, specifically complicated by macular edema. This indicates significant microvascular damage to the retina, leading to fluid accumulation in the macula, which can severely impair central vision.

Use this code when documentation clearly states a diagnosis of Type 1 diabetes and severe nonproliferative diabetic retinopathy with macular edema in both eyes. This typically follows an ophthalmological examination, such as fundus photography or optical coherence tomography (OCT), confirming the severity and presence of macular edema.

• Ensure documentation specifies "Type 1 diabetes" and "severe nonproliferative" retinopathy.
• Verify that macular edema is explicitly documented as present and affecting both eyes.
• Do not use if the retinopathy is proliferative or if macular edema is unilateral or absent.
