A07.8 ICD-10-CM Code: Other specified protozoal intestinal diseases

A07.8 is the ICD-10-CM diagnosis code for other specified protozoal intestinal diseases. This code describes intestinal infections caused by parasitic organisms (protozoans) that don't fit into other specific protozoal disease categories. These infections affect the digestive system and can cause symptoms like diarrhea and abdominal discomfort. A07.8 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering intestinal infectious diseases (a00-a09).

A07.8 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.

Use this code only when the specific protozoal organism is identified but doesn't match codes A07.0-A07.3 (cryptosporidiosis, isosporiasis, cyclosporiasis, or giardiasis); always document the specific organism name in the medical record.
