CPT® Code 88249

Chromosome analysis for breakage syndromes; score 100 cells, clastogen stress (eg, diepoxybutane, mitomycin C, ionizing radiation, UV radiation)

A chromosome analysis for breakage syndromes, as described by CPT® Code 88249, involves a detailed examination of chromosomes to identify potential breakage syndromes. This analysis specifically scores 100 cells and incorporates a clastogen stress test, which utilizes agents such as diepoxybutane, mitomycin C, ionizing radiation, or UV radiation to induce stress on the cells. Breakage syndromes are genetic disorders characterized by an increased susceptibility to chromosome breakage, which can lead to various health issues. The analysis is crucial for diagnosing conditions like Fanconi anemia and other related syndromes. The procedure is performed on peripheral blood lymphocytes, which are cultured and stimulated to divide, allowing for a comprehensive evaluation of the chromosomes. The use of clastogenic agents enhances the likelihood of detecting chromosome breakage that may not be evident under normal conditions, thereby providing valuable insights into the genetic status of the patient.
