Billable diagnosis code
CDC/NCHS · FY2026Coverage depends on the payer, service and applicable policy. A billable code does not guarantee payment.
For US diagnosis claims covered by HIPAA, ICD-10-CM is required from October 1, 2015.
Use the service date for outpatient/professional claims and the discharge date for hospital inpatient claims. Earlier encounters use ICD-9-CM; each individual code must also be valid for the applicable date.
