Diabetes with severe nonp rtnop with macular edema, unsp

This code describes a form of diabetes that is secondary to another underlying disease or condition, rather than being Type 1 or Type 2 diabetes. The patient also presents with severe nonproliferative diabetic retinopathy, characterized by significant retinal damage without new blood vessel growth, and macular edema, which is swelling in the central part of the retina, affecting vision in an unspecified eye.

This code is used when documentation clearly indicates diabetes mellitus is a consequence of another primary condition (e.g., cystic fibrosis, pancreatectomy, drug-induced) and not an idiopathic form. It is appropriate when the ophthalmologist's or endocrinologist's notes confirm severe nonproliferative diabetic retinopathy with macular edema, but the specific eye affected is not documented.

• Always sequence the underlying condition causing the diabetes first, followed by this code.
• Ensure documentation specifies "severe" nonproliferative retinopathy and the presence of macular edema.
• If the affected eye (right, left, or bilateral) is specified, a more specific code from the E08.341- subcategory should be used.
