Abatacept (immunosuppressive) injection, billed per 10 mg of dose administered

This code represents the administration of abatacept, an immunosuppressive drug used to treat autoimmune diseases. Abatacept is a selective T-cell co-stimulation modulator that inhibits T-lymphocyte activation, reducing inflammation and disease progression. It is typically administered via intravenous infusion or subcutaneous injection.

Use this code for the professional service of administering abatacept, primarily for conditions such as rheumatoid arthritis, psoriatic arthritis, and juvenile idiopathic arthritis. Documentation should clearly indicate the drug name, dosage administered (in 10 mg increments), route of administration, and the medical necessity for its use.

• Report this code in 10 mg increments based on the total dose administered, rounding up to the nearest 10 mg if necessary.
• Do not confuse this code with codes for other biologic agents or for the drug supply itself (J-codes for drug supply are separate).
• Ensure the medical record supports the specific diagnosis requiring abatacept therapy and the administered dosage.
