2025 Billable ICD-10-CM Codes
The 2025 Billable ICD-10-CM Codes list includes 74,260 diagnosis codes that meet the highest level of specificity required for HIPAA-covered claims. Billable codes ensure accurate reimbursement and compliance with Medicare and payer standards. Coders should always aim to use billable codes supported by medical documentation, as they most precisely reflect the patient’s condition and avoid unnecessary claim denials.
