Intramuscular administration of human immune globulin.

Always refer to the most current AMA CPT guidelines and payer-specific coding rules. The code should be used in conjunction with the appropriate administration codes and should not be reported with modifier 51 when performed with another procedure. The immunoglobulin product itself should be billed separately. Codes 90281-90399 identify serum globulins from human blood or recombinant immune globulin products.Consult the AMA CPT website for the most up-to-date information on these codes.

Modifiers may be applicable depending on the circumstances of the service. Consult the CPT codebook for specific modifier guidelines.

Medical necessity for immune globulin administration is determined by the patient's clinical condition, such as primary immunodeficiency disorders, secondary immunodeficiencies (e.g., due to chemotherapy), or exposure to certain infectious diseases.Documentation supporting the medical necessity should include details about the patient's condition, the reason for administering the immune globulin, and the anticipated benefits of the treatment.

The physician or qualified healthcare professional is responsible for selecting the appropriate immune globulin product based on the patient's needs, preparing the injection, inspecting the injection site, administering the injection slowly using an appropriately sized needle, and monitoring the patient for any adverse reactions.

IMPORTANT:This code should be used in conjunction with administration codes (96365-96375) for appropriate reimbursement. Modifier 51 should not be used with this code when multiple procedures are performed.

In simple words: This code covers the injection of a medicine called immune globulin into a muscle.Immune globulin helps protect against infections.The cost of the medicine itself is billed separately.
