What This Code Means
Z74.9 is the ICD-10-CM diagnosis code for problem related to care provider dependency, unspecified. A person has a problem related to depending on a caregiver, but the specific nature of the problem is not specified or documented. Z74.9 sits in the ICD-10-CM chapter for factors influencing health status and contact with health services (z00-z99), within the section covering persons encountering health services in other circumstances (z69-z76).
Z74.9 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.
This is a default code; attempt to use more specific codes (Z74.2, Z74.3, Z74.8) whenever possible.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for Z74.9 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
