What This Code Means
H52.10 is the ICD-10-CM diagnosis code for myopia, unspecified eye. Myopia, commonly known as nearsightedness, is a refractive error where a person can see nearby objects clearly but distant objects appear blurry. This code is used when the condition affects an unspecified eye or when the laterality (which eye) is not documented. H52.10 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).
H52.10 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.
If the myopia affects a specific eye (right, left, or both), use the more specific codes H52.11 (right eye), H52.12 (left eye), or H52.13 (bilateral) instead of the unspecified code H52.10.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H52.10 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •If the myopia affects a specific eye (right, left, or both), use the more specific codes H52.11 (right eye), H52.12 (left eye), or H52.13 (bilateral) instead of the unspecified code H52.10
- •Myopia is typically a chronic condition; ensure documentation specifies the degree of myopia (mild, moderate, high) if available, as there are separate codes for different severities
