Type 2 diabetes w unsp diabetic retinopathy w macular edema

This code signifies a patient diagnosed with type 2 diabetes mellitus who also presents with diabetic retinopathy, specifically involving macular edema, where the specific type of retinopathy (e.g., proliferative, nonproliferative) is not documented. It indicates the presence of vision-threatening retinal swelling due to diabetic microvascular damage.

Apply this code when documentation confirms type 2 diabetes and diabetic macular edema, but the ophthalmologist or optometrist does not specify whether the retinopathy is nonproliferative or proliferative. This is appropriate when the focus is on the presence of macular edema complicating the diabetes.

• Always sequence the diabetes code first, as it is the underlying systemic condition.
• Do not use this code if the type of diabetic retinopathy (e.g., mild nonproliferative, severe nonproliferative, proliferative) is specified; instead, use the more specific code.
• Ensure documentation clearly states "macular edema" in conjunction with diabetic retinopathy.
