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

This code signifies a patient diagnosed with Type 1 diabetes who also presents with severe nonproliferative diabetic retinopathy, complicated by macular edema. This retinal complication involves significant microvascular damage without new vessel formation, specifically affecting the macula, which is crucial for central vision.

Apply this code when documentation clearly states Type 1 diabetes and severe nonproliferative diabetic retinopathy with macular edema. This diagnosis typically arises from ophthalmologic examinations, such as fundus photography or optical coherence tomography (OCT), confirming the severity of retinopathy and the presence of macular edema.

• Ensure the documentation specifies "severe" nonproliferative retinopathy; mild or moderate forms require different codes.
• Verify the presence of macular edema; its absence would lead to a different code for nonproliferative retinopathy.
• This code is for an "unspecified eye"; if the affected eye (right or left) is documented, a more specific code should be used.
