What This Code Means
H27.133 is the ICD-10-CM diagnosis code for posterior dislocation of lens, bilateral. The lens of both eyes has moved backward from its normal position, which can affect vision and may require surgical correction. This condition can occur due to trauma, genetic disorders, or age-related changes. H27.133 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of lens (h25-h28).
H27.133 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 that the dislocation is confirmed as bilateral (affecting both eyes) before assigning this code; if only one eye is affected, use the unilateral code H27.131 instead.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H27.133 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify that the dislocation is confirmed as bilateral (affecting both eyes) before assigning this code; if only one eye is affected, use the unilateral code H27.131 instead
- •Document the underlying cause if known (trauma, Marfan syndrome, homocystinuria, etc.) as this may require additional coding and affects treatment planning
