Drug/chem diab with prolif diab rtnop with comb detach, bi

This code describes a specific type of diabetes mellitus caused by drugs or chemicals, rather than an autoimmune process or insulin resistance. The patient presents with severe eye complications, specifically proliferative diabetic retinopathy, which has led to both tractional and rhegmatogenous retinal detachments affecting both eyes. This indicates advanced and complex ocular involvement.

Use this code when documentation clearly states that diabetes is drug or chemical induced, and the patient has bilateral proliferative diabetic retinopathy with a combined tractional and rhegmatogenous retinal detachment. This code is appropriate for patients with significant vision-threatening complications directly attributable to the diabetic state.

• Ensure documentation explicitly links the diabetes to drug or chemical causation.
• Verify that both tractional and rhegmatogenous components of retinal detachment are present and bilateral.
• Do not use this code for Type 1 or Type 2 diabetes; a different code series is required for those etiologies.
