What ICD-10 Codes are Used for History Of Appendectomy 

There is only one history of appendectomy ICD code you can use for medical billing and coding. This ICD code is Z90.49 - Acquired absence of other specified parts of digestive tract.

This code is intended for patients with a confirmed acquired absence of a specific part or parts of their digestive tracts. Since the appendix is situated at the junction of the small intestine and large intestine, this ICD-10 code can be used if it has been previously removed by appendectomy.

It's important to note that this ICD-10 code is not appropriate as a primary diagnosis, as its purpose is to indicate the acquired absence of a digestive tract part rather than diagnosing a medical condition or issue.

Is this history of appendectomy ICD code billable?

Yes. This history of appendectomy-related ICD-10 code is valid and billable.

Clinical information

  • An appendectomy is the surgical procedure of removing a person’s appendix, a part of the digestive tract. 
  • It is the best method of dealing with an inflamed appendix, referred to as appendicitis. 
  • People with inflamed appendix will feel pain in their lower right abdomen. 
  • If left untreated, it’ll cause more pain and even death. 
  • This pain can be aggravated by simply walking, coughing, or other movements. 
  • This is surprising because no one knows what the appendix's function is, and yet, an inflammation of it can cause so much trouble and lead to death.

Synonyms include:

  • History of appendectomy
