Type 1 diab with mod nonp rtnop without macular edema, unsp

This code signifies a patient diagnosed with Type 1 diabetes who has developed moderate nonproliferative diabetic retinopathy (NPDR) without macular edema. This stage of retinopathy involves microaneurysms, hemorrhages, and cotton wool spots in the retina, but without the more severe neovascularization or fluid leakage affecting central vision. The "unspecified eye" indicates that the laterality of the retinopathy is not documented.

Use this code when documentation clearly states Type 1 diabetes and moderate nonproliferative diabetic retinopathy is present, and specifically notes the absence of macular edema. This code is appropriate when the physician's assessment does not specify whether one or both eyes are affected, or if the affected eye is not explicitly stated. Supporting documentation includes ophthalmology reports detailing funduscopic findings, retinal imaging (e.g., OCT, fluorescein angiography), and the patient's diabetes management plan.

• Always confirm the type of diabetes (Type 1 vs. Type 2) and the severity of retinopathy (mild, moderate, severe NPDR, or PDR).
• Ensure documentation explicitly states "without macular edema" to avoid using codes that include macular edema.
• If laterality is specified (e.g., right eye, left eye, bilateral), use a more specific code from the E10.33 category.
