Diabetes with prolif diabetic rtnop with combined detach, bi

This code signifies diabetes mellitus resulting from an underlying non-diabetic condition, complicated by advanced diabetic retinopathy. Specifically, it indicates the presence of new blood vessel growth on the retina (proliferative diabetic retinopathy) that has led to both a tractional retinal detachment (due to fibrous tissue pulling on the retina) and a rhegmatogenous retinal detachment (due to a retinal tear allowing fluid under the retina), affecting both eyes.

Use this code when documentation clearly states diabetes mellitus secondary to another condition (e.g., cystic fibrosis, pancreatectomy) and bilateral proliferative diabetic retinopathy with combined tractional and rhegmatogenous retinal detachments. This code requires explicit mention of both types of detachment in both eyes.

• Ensure the underlying condition causing the diabetes is also coded, typically as the primary diagnosis, with this code following as a secondary diagnosis.
• Verify documentation specifies both tractional and rhegmatogenous detachments in both eyes; otherwise, a different code for a single type of detachment or unilateral involvement would be more appropriate.
• Distinguish from codes for type 1 or type 2 diabetes with similar ophthalmic complications; this code is specifically for diabetes due to an underlying condition.
