What This Code Means
H50.22 is the ICD-10-CM diagnosis code for vertical strabismus, left eye. This condition occurs when the left eye is misaligned vertically, meaning it points either upward or downward compared to the right eye, causing the eyes to not focus together on the same object. This misalignment can result in double vision, eye strain, or difficulty with depth perception. H50.22 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of ocular muscles, binocular movement, accommodation and refraction (h49-h52).
H50.22 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Verify whether the vertical deviation is hypertropia (eye turned up) or hypotropia (eye turned down), as this may affect clinical documentation and treatment planning.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H50.22 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify whether the vertical deviation is hypertropia (eye turned up) or hypotropia (eye turned down), as this may affect clinical documentation and treatment planning
- •Ensure you have documented which eye is affected (left eye in this case) and confirm this matches the clinical record before assigning the code
