2026 ICD-10-CM Diagnosis Code QA0

Neurodevelopmental disorders related to specific genetic pathogenic variants

ICD-10-CM Code:
QA0
ICD-10 Code for:
Neurodev disord related to specific genetic patho variants
Is Billable?
Not Valid for Submission
Code Navigator:

QA0 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of neurodevelopmental disorders related to specific genetic pathogenic variants. The code is not specific and is NOT valid for the year 2026 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Neurodev disord related to specific genetic patho variants

Non-specific codes like QA0 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for neurodev disord related to specific genetic patho variants:

  • QA0.0 for Neurodevelopmental disorders related to pathogenic variants in specific genes - NON-BILLABLE CODE

  • QA0.01 for Neurodevelopmental disorders related to pathogenic variants in certain specific genes - NON-BILLABLE CODE

  • Use QA0.8 for Other neurodevelopmental disorders related to pathogenic variants in other specific genes - BILLABLE CODE
