What This Code Means
B80 is the ICD-10-CM diagnosis code for enterobiasis. Enterobiasis is a parasitic infection caused by pinworms (small roundworms) that live in the colon and rectum, commonly affecting children and causing itching around the anus, especially at night. The infection spreads through ingestion of microscopic eggs and is easily treatable with medication. B80 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering helminthiases (b65-b83).
B80 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.
Enterobiasis is typically an outpatient diagnosis; ensure documentation specifies the site of infection if there are complications affecting other body systems.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for B80 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Enterobiasis is typically an outpatient diagnosis; ensure documentation specifies the site of infection if there are complications affecting other body systems
- •This code does not require a fifth character for laterality or severity; verify that the provider has confirmed the diagnosis through clinical presentation or laboratory findings (stool sample or tape test) before coding
Includes
- oxyuriasis
- pinworm infection
- threadworm infection
