What it is
This code identifies stage 2 retinopathy of prematurity affecting the left eye. It describes a moderate retinal finding in a premature infant, documented by eye examination.
Clinical signs
Stage 2 ROP is characterized by a distinct ridge at the junction of vascular and avascular retina. Clinical features vary; refer to documentation for laterality and stage confirmation.
When to use this code
Use H35.132 when the provider documents stage 2 retinopathy of prematurity in the left eye. Apply it after ophthalmologic evaluation confirms the stage and eye involved. If the note does not specify laterality, check documentation before coding.
Do not use for
Do not use this code for retinopathy of prematurity in another stage or in the right eye. Do not assume laterality or severity when the record is incomplete; check documentation.
Coding tip
Code the stage and eye exactly as documented, and query the provider if either detail is missing.
