00.18 — Infusion of immunosuppressive antibody therapy

00.18 is an ICD-9-CM procedure code for infusion of immunosuppressive antibody therapy. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-PCS took over.

The CMS General Equivalence Mappings translate it to 70 ICD-10-PCS codes, such as 3E00X0M (Introduction of Antineoplastic, Monoclonal Antibody, into Skin and Mucous Membranes, External Approach), 3E0130M (Introduction of Antineoplastic, Monoclonal Antibody, into Subcutaneous Tissue, Percutaneous Approach) and 3E0230M (Introduction of Antineoplastic, Monoclonal Antibody, into Muscle, Percutaneous Approach). All of these are approximate matches, so review the record to pick the right one.
