Diab with prolif diab rtnop with trctn dtch n-mcla, left eye

This code signifies diabetes mellitus resulting from another underlying medical condition, complicated by advanced diabetic retinopathy. Specifically, it indicates the presence of new blood vessel growth (proliferative retinopathy) in the left eye, which has led to a traction retinal detachment that does not involve the macula.

Apply this code when documentation clearly states a patient has diabetes secondary to another condition (e.g., cystic fibrosis, pancreatectomy) and presents with proliferative diabetic retinopathy in the left eye, complicated by a non-macula-involving tractional retinal detachment. Supporting documentation should include ophthalmological exam findings detailing the specific type and location of the retinal detachment.

• Always code the underlying condition causing the diabetes first, followed by this code.
• Ensure documentation specifies "left eye" and "not involving the macula" for accurate laterality and severity.
• Differentiate from rhegmatogenous or exudative retinal detachments, as this code is specific to tractional detachment due to proliferative diabetic retinopathy.
