Drug/chem diabetes with stable prolif diabetic rtnop, unsp

This code signifies diabetes mellitus that has been induced by a drug or chemical agent, rather than being an autoimmune or idiopathic process. The patient presents with stable proliferative diabetic retinopathy, indicating a severe form of retinal damage due to diabetes where new, fragile blood vessels have grown but are currently not actively hemorrhaging or causing acute vision loss. The specific eye affected is not documented.

Use this code when documentation clearly states drug or chemical-induced diabetes mellitus and stable proliferative diabetic retinopathy. This code is appropriate when the medical record specifies the retinopathy is stable, meaning no active progression or acute complications are noted at the time of encounter. Supporting documentation should include the causative drug/chemical and an ophthalmological assessment confirming stable proliferative retinopathy.

• Always sequence the drug/chemical code (T36-T65 with 5th or 6th character 5) first, followed by this diabetes code.
• Distinguish from E10.3559 (Type 1) or E11.3559 (Type 2) diabetes with proliferative retinopathy; the key differentiator is the drug/chemical etiology.
• Ensure documentation explicitly states "stable" proliferative retinopathy; otherwise, a code for active proliferative retinopathy may be more appropriate.
