Revised ICD-10 Codes for Diagnosed Conditions with a High Probability of Resulting in Developmental Delay (August 2026)

Dear Colleague:

The New York State Department of Health (Department) Bureau of Early Intervention is issuing the attached revised list of ICD-10 codes Diagnosed Conditions with a High Probability of Resulting in Developmental Delay (August 2026). This updated list includes the addition of Q77.6 - Chondroectodermal dysplasia. This code has been included in the State Data System (EI-Hub).

For children with a confirmed disability (i.e., a diagnosed condition with a high probability of developmental delay), a full multidisciplinary evaluation (MDE) must be performed. The purpose of an MDE is to confirm the diagnosis through a review of appropriate medical or other records, with parent consent; and, to conduct an evaluation and assessment of all developmental domains to assist in the development of the Individualized Family Service Plan (IFSP). These children do not have to be experiencing developmental delays to receive specific services as the primary purpose of early intervention is to mitigate the impact of the condition on a child’s developmental progress.

In the EI-Hub, all existing ICD-10 codes are available to be added to a child’s record. If a user needs an ICD-10 code reviewed to determine if it is a diagnosed condition with a high probability of delay, please enter a Web-to-Case ticket with the subject line “ICD-10 Code for EI Eligibility Consideration .” This ensures your request is tracked and sent to the Bureau of Early Intervention (BEI) for processing according to the standard review procedure.
