CPT Codes from this section of the CPT coding system are used to report invasive and surgical procedures performed on the lips; tongue; dentoalveolar structures; palate; salivary gland; pharynx, adenoids and tonsils; esophagus;stomach; intestines; rectum; anus; liver; biliary tract; pancreas; and the abdomen, peritoneum, and omentum.


Gastrointestinal endoscopy codes should be assigned based on the extent of visualization performed. CMS’s official guidelines for excision or destruction of a lesion are:

  1. 1.                            Use only the biopsy code if a single lesion is biopsied but not excised;
  1. 2.                            Code only for the excision if a lesion is biopsied and the remaining portion is excised;
  1. 3.                            Use the biopsy code once even if multiple biopsies are performed and none are excised; and
  1. 4.                            Use both a biopsy and excision code if each lesion is taken from different sites.

If the phrase “with or without biopsy” appears in the excision code’s narrative, do not use a separate biopsy code. Diagnostic endoscopies are included in surgical endoscopies.

For upper gastrointestinal endoscopies, choose the appropriate code from documentation indicating whether the procedure was a simple exam, a diagnostic procedure or surgical procedure. Remember that code selection is based on the procedure(s) performed and the anatomical sites through which the scope passes. For example, if the scope is passed to the esophagus only, the code would be chosen from endoscopy codes beginning with 43200. If the scope is passed through the esophagus to the stomach, duodenum and/or the jejunum, the code selection would begin at 43235.


Review the patient’s age, the kind of hernia, the clinical presentation of the hernia, and method of repair documented in the medical record before assigning a hernia repair coded.


To code appendectomies appropriately, review the documentation for an indicated purpose for the removal. If there is none, then it is probably incidental to a more serious surgery and should not be coded.
