Oth diab with moderate nonp rtnop with macular edema, l eye

This code describes a patient diagnosed with a form of diabetes mellitus other than type 1 or type 2, who also presents with moderate nonproliferative diabetic retinopathy affecting the macula of the left eye due to swelling. This indicates a specific stage of diabetic eye disease with central vision involvement.

Use this code when documentation clearly states "other specified diabetes mellitus" and confirms moderate nonproliferative diabetic retinopathy with macular edema in the left eye. This is typically supported by ophthalmological examination findings, including fundus photography, OCT scans, and physician notes detailing the severity and laterality.

• Ensure the documentation specifies "other specified diabetes mellitus" and not type 1 or type 2.
• Verify the laterality (left eye) and the specific stage of retinopathy (moderate nonproliferative) and presence of macular edema.
• Always code the underlying diabetes first, followed by the manifestation code for retinopathy.
