What This Code Means
Z73.810 is the ICD-10-CM diagnosis code for behavioral insomnia of childhood, sleep-onset association type. A sleep disorder in children where they have difficulty falling asleep without specific associations or conditions, such as needing a parent present or certain objects to initiate sleep. Z73.810 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).
Z73.810 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 code is used for children who cannot initiate sleep independently and require specific sleep-onset associations.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for Z73.810 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
