Diab with prolif diabetic rtnop with comb detach, left eye

This code signifies a specific complication of diabetes mellitus that arises from an underlying condition, rather than type 1 or type 2 diabetes. The patient presents with proliferative diabetic retinopathy (PDR) in the left eye, which has progressed to involve both tractional and rhegmatogenous retinal detachments. This represents a severe, vision-threatening ocular complication.

Use this code when documentation clearly states diabetes mellitus due to an underlying condition (e.g., cystic fibrosis, pancreatectomy) and specifies proliferative diabetic retinopathy with both tractional and rhegmatogenous retinal detachments in the left eye. The physician's notes must explicitly differentiate the cause of diabetes from type 1 or type 2.

• Ensure the documentation specifies "due to underlying condition" for the diabetes type; otherwise, a different E08 subcategory is appropriate.
• Verify that both tractional and rhegmatogenous detachments are present and documented for the left eye.
• Always sequence the underlying condition code first, followed by this diabetes complication code.
