Retinopathy of prematurity, stage 1, bilateral

📋Clinical Description

This code describes the presence of retinopathy of prematurity (ROP) affecting both eyes, specifically at stage 1. ROP is an abnormal blood vessel development in the retina of premature infants, and stage 1 is characterized by a demarcation line separating vascularized from avascular retina. This stage indicates the mildest form of the disease.

🎯When to Use

Use this code for premature infants diagnosed with stage 1 ROP in both eyes. Documentation should clearly specify the stage of ROP and confirm bilateral involvement, typically from an ophthalmologist's examination report. This code is appropriate when no treatment for ROP has yet been initiated.

💡Coding Tips

Ensure the documentation explicitly states "stage 1" and "bilateral" involvement.
Do not use this code if only one eye is affected; use the appropriate unilateral code.
Sequence this code after codes for prematurity or low birth weight, if applicable.
