Neurodevelopmental disorders related to specific genetic pathogenic variants (QA0)

Browse all the diagnosis codes used for neurodevelopmental disorders related to specific genetic pathogenic variants (QA0). For easy navigation, the diagnosis codes are sorted in alphabetical order and grouped by sections. Each section is clearly marked with its description, and the corresponding three-digit code range. This format makes it simple to browse diagnosis codes in this chapter or section and find what you're looking for. We've also added green checkmark icons to label billable codes, and red warning icons for non-billable ones. This makes it easy to identify which codes can be billed.
