Gastric intubation, as described by CPT® Code 91055, refers to the medical procedure in which a tube is inserted into the stomach through either the nose or mouth. This procedure is performed to collect gastric washings, which are fluid samples obtained from the stomach. The primary purpose of these washings is for cytological examination, which involves the study of cells to identify any abnormalities or diseases. The process includes the preparation of the specimens for analysis, ensuring that the samples are suitable for cytological evaluation. It is important to note that this procedure is classified as a separate procedure, indicating that it is distinct from other related procedures and may be billed independently. The use of gastric intubation for cytology is a critical diagnostic tool in evaluating gastrointestinal conditions and potential malignancies.
