What This Code Means
Y77.0 is the ICD-10-CM diagnosis code for diagnostic and monitoring ophthalmic devices associated with adverse incidents. An adverse event or injury caused by a problem with diagnostic or monitoring devices used in eye care, such as tonometers or optical coherence tomography machines. Y77.0 sits in the ICD-10-CM chapter for external causes of morbidity (v00-y99), within the section covering medical devices associated with adverse incidents in diagnostic and therapeutic use (y70-y82).
Y77.0 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.
Document the specific diagnostic or monitoring device that caused the adverse incident.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for Y77.0 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Document the specific diagnostic or monitoring device that caused the adverse incident
- •This code is for complications arising from the use of diagnostic equipment in ophthalmology, not from the findings themselves
