What This Code Means
A52.71 is the ICD-10-CM diagnosis code for late syphilitic oculopathy. This is an eye disease caused by syphilis that develops years after the initial infection. It can affect vision and various structures of the eye. A52.71 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering infections with a predominantly sexual mode of transmission (a50-a64).
A52.71 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 syphilis is documented as 'late' stage (typically occurring more than 2 years after initial infection) to distinguish from early syphilitic eye conditions.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for A52.71 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify that the syphilis is documented as 'late' stage (typically occurring more than 2 years after initial infection) to distinguish from early syphilitic eye conditions
- •Ensure the documentation specifies the eye involvement is related to syphilis; may need to code the underlying late syphilis (A52.7x) in addition to this code
