2007 ICD-9-CM Procedure 92.28 Injection or instillation of radioisotopes Radiotherapy where cytotoxic radionuclides are linked to antibodies in order to deliver toxins directly to tumor targets. Therapy with targeted radiation rather than antibody-targeted toxins (IMMUNOTOXINS) has the advantage that adjacent tumor cells, which lack the appropriate antigenic determinants, can be destroyed by radiation cross-fire. Radioimmunotherapy is sometimes called targeted radiotherapy, but this latter term can also refer to radionuclides linked to non-immune molecules (see RADIOTHERAPY). Treatment with a radioactive substance that is linked to an antibody so that it will attach to a tumor when injected into the body. Treatment with a radioactive substance that is linked to an antibody that will attach to the tumor when injected into the body. 92.28 is a specific code that can be used to specify a procedure 92.28 contains 8 index entries View the full Volume 3 92.* hierarchy 92.28 also known as: Injection or infusion of radioimmunoconjugate Intracavitary injection or instillation Intravenous injection or instillation Iodine-131 [I-131] tositumomab Radioimmunotherapy Ytrium-90 [Y-90] ibritumomab tiuxetan 92.28 excludes: infusion of liquid brachytherapy radioisotope (92.20) Index entries containing 92.28: Infusion (intra-arterial) (intravenous) radioimmunoconjugate 92.28 radioimmunotherapy 92.28 Injection (into) (hypodermically) (intramuscularly) (intravenously) (acting locally or systemically) radioimmunoconjugate 92.28 radioimmunotherapy 92.28 radioisotopes (intracavitary) (intravenous) 92.28 Instillation radioisotope (intracavitary) (intravenous) 92.28 Radioimmunotherapy 92.28 Therapy radioisotope, radioisotopic NEC 92.29 injection or instillation 92.28
