Diab with prolif diabetic rtnop with trctn dtch macula, bi

This code signifies diabetes mellitus that has developed as a consequence of another underlying disease, rather than being primary type 1 or type 2 diabetes. The patient presents with advanced diabetic eye disease, specifically proliferative diabetic retinopathy, which has led to tractional retinal detachment affecting the macula in both eyes. This represents a severe, vision-threatening complication of secondary diabetes.

Use this code when documentation clearly states diabetes is secondary to another condition (e.g., cystic fibrosis, pancreatectomy, drug-induced) and bilateral proliferative diabetic retinopathy with macular-involving tractional retinal detachment is present. This code requires explicit linkage of the diabetes to an underlying cause and specific ophthalmic findings.

• Always sequence the underlying condition causing the diabetes first, followed by this code.
• Ensure documentation specifies "proliferative" retinopathy and "tractional" detachment involving the "macula" in "bilateral" eyes.
• Differentiate from non-proliferative retinopathy or serous/rhegmatogenous detachments, which would require different codes.
