How coders use this code

ICD-10-CM G40.42 is a billable, fully specified code, so it can be reported directly on a claim to document a diagnosis of cyclin-dependent kinase-like 5 deficiency disorder. Coders assign it when the chart documentation supports this level of detail, always matching to the most specific code available and verifying against the chapter-specific guidelines published annually by NCHS/CMS.
