CPT® Code 88237

The CPT® Code 88237 refers to a laboratory procedure known as tissue culture for neoplastic disorders, specifically focusing on bone marrow and blood cells. This procedure involves culturing cells and/or tissue samples from patients who are suspected of having or are known to have neoplastic disorders, which are conditions characterized by the abnormal growth of cells, such as cancer. The primary objective of this test is to identify various genetic and chromosomal characteristics, including chromosomes, hereditary genotypes, mutations, phenotypes, and karyotypes. These analyses are crucial for diagnosing, prognosing, and monitoring hematopoietic diseases, which affect the blood and bone marrow. To perform this test, whole blood is collected from the patient through a procedure known as venipuncture, which is separately reportable. Additionally, bone marrow samples can be obtained through aspiration, and solid tumors, such as lymph nodes, may be excised or biopsied, with these procedures also being separately reportable. The laboratory utilizes specific staining techniques, such as Giemsa Band, for testing whole blood and solid tissue samples. For bone marrow samples, testing may involve Giemsa Band or advanced techniques like cell culture fluorescence in situ hybridization (FISH), which allows for the visualization of genetic material within the cells. This comprehensive approach aids healthcare professionals in making informed decisions regarding patient care and treatment options based on the genetic and chromosomal information obtained from the tissue cultures.
