This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
An eye condition in premature infants where abnormal blood vessels develop in the retina (back of the eye), classified as stage 1 severity in the left eye.
Coding Tips
- •Stage 1 ROP is the mildest form; always specify laterality (left, right, bilateral, or unspecified)
- •ROP codes require documentation of the stage (1-5) and affected eye(s); this is commonly seen in infants with low birth weight or prolonged oxygen exposure
