Diabetes with prolif diabetic rtnop with macular edema, unsp

This code signifies a patient diagnosed with diabetes mellitus that is a direct consequence of another underlying medical condition, rather than type 1 or type 2 diabetes. The patient also presents with proliferative diabetic retinopathy affecting an unspecified eye, further complicated by macular edema. This indicates advanced diabetic eye disease with vision-threatening complications.

Apply this code when documentation clearly states diabetes is secondary to another condition (e.g., cystic fibrosis, pancreatectomy, drug-induced) and specifies proliferative diabetic retinopathy with macular edema. The physician's notes must explicitly link the diabetes to the underlying cause and detail the specific ocular complications.

• Always sequence the underlying condition causing the diabetes first, followed by this code.
• Ensure documentation specifies "proliferative" retinopathy and "macular edema" to differentiate from other forms of diabetic retinopathy.
• Verify laterality if specified; this code is for an unspecified eye.
