In simple words: This code describes a type of eye damage (retinopathy) caused by type 1 diabetes, where the central part of the eye (macula) responsible for sharpest vision becomes swollen.

Type 1 diabetes mellitus with mild nonproliferative diabetic retinopathy with macular edema. This condition involves damage to the retinal blood vessels due to chronically high blood glucose levels, leading to microaneurysms, hemorrhages, and swelling of the macula (the central part of the retina responsible for sharp vision).

Example 1: A patient with a long-standing history of type 1 diabetes presents with blurred vision and recent onset of macular edema confirmed by ophthalmological examination., A routine eye exam for a type 1 diabetic patient reveals mild NPDR and macular edema. The patient reports no noticeable vision changes., An adolescent newly diagnosed with type 1 diabetes undergoes an eye exam which reveals no retinopathy initially, however mild NPDR and macular edema is found a year later.

Documentation should include: type 1 diabetes diagnosis, details of the ophthalmological examination (e.g., fundus photography, fluorescein angiography), presence and severity of NPDR, presence of macular edema, and any associated symptoms (e.g., blurred vision).

** Regular monitoring of diabetes and annual eye exams for diabetic retinopathy are crucial for early detection and management.
