What history of diverticulitis ICD codes can I use?
There are no specific history of diverticulitis ICD codes, with history of diverticulitis in their names. Diverticulitis is a digestive condition/problem, and you can use two ICD-10 codes for patients with a history of digestive conditions:
- Z87.19 - Personal history of other diseases of the digestive system
This ICD-10 code is meant to be used for a patient confirmed to have a personal history of having diseases of the digestive system, so if they’ve ever had diverticulitis before, you can use this ICD-10 code.
- Z83.79 - Family history of other diseases of the digestive system
This ICD-10 code is meant to be used for a patient confirmed to have a family history of having diseases of the digestive system, so if the patient’s relatives/ancestors ever had diverticulitis, you can use this ICD-10 code.
Do note that both of these codes are not exactly diagnoses. They’re even considered to be unacceptable as principal diagnoses because they’re about having a history of digestive diseases. At the very least, these can be used to designate a person's risk of diverticulitis given they have a personal or family history of having it or some other digestive condition.
