2025 ICD-10-CM code T18.2

Foreign body in the stomach.

Consult the official ICD-10-CM coding guidelines for the most up-to-date information on coding rules and conventions.

ICD-10 codes do not utilize modifiers.

Medical necessity is established by the presence of a foreign body in the stomach posing a risk of complications such as obstruction, perforation, infection, or other injury. The necessity for removal is determined by the size, location, and nature of the foreign body, as well as the patient's clinical condition.

The clinical responsibility involves diagnosing the presence and location of the foreign body, assessing its potential risks, and determining the appropriate treatment strategy, which might include endoscopic removal, observation, or surgical intervention.

IMPORTANT:Additional codes may be necessary to specify the type of foreign body and the method of entry (e.g., W codes for external causes of injury).

In simple words: A foreign object is present in the stomach.This could be something that was swallowed accidentally or on purpose. Doctors will need to use imaging tests like X-rays or a scope to see it.

This code signifies the presence of a foreign body within the stomach.The foreign body may be ingested accidentally or intentionally.This diagnosis requires confirmation through appropriate imaging studies (e.g., X-ray, CT scan) or endoscopy.

Example 1: A child accidentally swallows a small toy, resulting in a foreign body in the stomach. An abdominal X-ray confirms the presence of the object.Endoscopy is performed to retrieve the object., An adult intentionally ingests a large number of small metal objects. An abdominal X-ray shows multiple foreign bodies in the stomach. Surgical intervention is required to remove them., A patient presents with abdominal pain and nausea. A CT scan reveals a large, irregularly shaped foreign body in the stomach.The patient undergoes laparotomy (surgical opening of the abdominal cavity) to remove the object.

Detailed history of the incident, including how the foreign body entered the body.Imaging studies (X-ray, CT scan, or endoscopy) confirming the location and type of foreign body.Documentation of the procedure used for removal (endoscopy, surgery).Physician's notes detailing the patient's symptoms, findings, treatment and outcome.
