For which procedure would 38570-38589 be the appropriate code range?

The code range 38570-38589 corresponds to various procedures related to lymphatic system interventions, specifically lymphadenectomy and lymph node biopsy. These procedures are commonly associated with accessing lymph nodes and tissues often performed during laparoscopic surgeries to evaluate or treat cancers or other medical conditions affecting the lymphatic system.

This code range is not applicable to excision of lesions, esophagoscopy, or injection procedures. Excision of a lesion would fall under a different set of codes that cover specific excisions, esophagoscopy codes relate to procedures concerning the esophagus, and injection procedures would have their own distinct codes for various therapeutic or diagnostic injections. Therefore, the connection of the specified code range to laparoscopic surgery is supported by the nature of the procedures involved within that range.
