What This Code Means
R62.0 is the ICD-10-CM diagnosis code for delayed milestone in childhood. A child is not reaching expected developmental milestones for their age, such as walking, talking, or other skills. R62.0 sits in the ICD-10-CM chapter for symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (r00-r99), within the section covering general symptoms and signs (r50-r69).
R62.0 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 which specific milestones are delayed (motor, language, social) to support evaluation and intervention planning.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for R62.0 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Document which specific milestones are delayed (motor, language, social) to support evaluation and intervention planning
