About coding neurodevelopmental disorder
The ICD-10-CM code for neurodevelopmental disorder is F89 (Unspecified disorder of psychological development). The official index lists 24 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on F89.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 886 (Behavioral and Developmental Disorders, relative weight 1.8678), in MDC 19 (Mental Diseases and Disorders), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
