Type 1 diab with severe nonp rtnop without mclr edema, r eye

This code signifies a patient diagnosed with type 1 diabetes mellitus who also presents with severe nonproliferative diabetic retinopathy affecting the right eye, specifically without any associated macular edema. This stage of retinopathy indicates significant microvascular damage in the retina but has not progressed to the more advanced proliferative stage or caused fluid leakage in the macula.

Use this code when documentation confirms type 1 diabetes and ophthalmological findings of severe nonproliferative diabetic retinopathy exclusively in the right eye, with explicit absence of macular edema. This is typically supported by an ophthalmologist's examination notes, including fundus photography, optical coherence tomography (OCT) if performed, and a clear statement regarding the severity and laterality of the retinopathy.

• Ensure the documentation specifies "severe" nonproliferative retinopathy and clearly states "without macular edema" for the right eye.
• Verify the diabetes type is explicitly documented as "type 1" to differentiate from type 2 or unspecified diabetes.
• Always code the diabetes first, followed by the diabetic retinopathy, adhering to ICD-10-CM sequencing guidelines.
