CPT® Code 88233

A tissue culture is a laboratory procedure that involves obtaining a sample of tissue, such as skin or other solid tissues, to facilitate a chromosome analysis specifically for non-neoplastic disorders. Non-neoplastic disorders refer to genetic conditions that do not involve tumors or cancerous growths but may include a variety of genetic anomalies. These can encompass conditions such as sister chromatid exchange (SCE), breakage syndromes, trisomies, and mosaicism, among others. The purpose of this procedure is to promote cell growth from the biopsy sample, allowing for detailed genetic analysis. The process begins with the collection of a tissue biopsy, which is then cultured in a controlled environment to encourage the proliferation of cells. This is similar to the procedure outlined in CPT® Code 88230, where lymphocytes from a peripheral blood sample are cultured. In both cases, the cultured cells are subjected to specific treatments to prepare them for chromosome analysis, ensuring that a sufficient number of mitotic cells are available for accurate evaluation. The results of this analysis can provide critical insights into congenital or other genetic conditions that may affect the patient.
