Oth diab with mild nonp rtnop without macular edema, r eye

This code signifies a diagnosis of other specified diabetes mellitus, characterized by mild nonproliferative diabetic retinopathy affecting the right eye, without any evidence of macular edema. This indicates early-stage retinal damage due to diabetes, specifically in the right eye, but without the more severe complication of macular swelling.

Use this code when documentation confirms a patient has a type of diabetes mellitus not classified as Type 1 or Type 2 (e.g., secondary diabetes, genetic defects in beta-cell function) and presents with mild nonproliferative diabetic retinopathy in the right eye, explicitly stating the absence of macular edema. Supporting documentation would include ophthalmology reports detailing funduscopic findings, OCT scans confirming no macular edema, and a clear diagnosis of "other specified diabetes mellitus."

• Always ensure the laterality (right eye) and the absence of macular edema are clearly documented to support this specific code.
• Distinguish "other specified diabetes mellitus" from Type 1 (E10.-) or Type 2 (E11.-) diabetes, as the base code E13.- is specific to other forms.
• Verify the severity of retinopathy (mild nonproliferative) and the presence/absence of macular edema, as these factors significantly impact code selection.
