What This Code Means
H50.031 is the ICD-10-CM diagnosis code for monocular esotropia with v pattern, right eye. The right eye turns inward (toward the nose) with a V-pattern, meaning the inward turn is more pronounced when looking upward than downward. H50.031 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).
H50.031 is a billable ICD-10-CM code, but the current payload does not show a mapping under the CMS-HCC V28 or V24 community payment models, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.
Confirm V-pattern notation in clinical documentation to differentiate from A-pattern.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for H50.031 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Confirm V-pattern notation in clinical documentation to differentiate from A-pattern
- •Ensure right eye is specifically documented as the affected eye
