ICD-10-CM Codes›A00–B99›B65-B83›B65
- Billable — Valid for Submission
- CC — Complication or Comorbidity
- Not Chronic
B65.0 is a billable ICD-10-CM diagnosis code for schistosomiasis due to Schistosoma haematobium [urinary schistosomiasis]. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 689 through 690. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 6 closely related codes. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Parasitic, other specified and unspecified infections.

Parasites are living things that use other living things - like your body - for food and a place to live. You can get them from contaminated food or water, a bug bite, or sexual contact. Some parasitic diseases are easily treated and some are not.
