What This Code Means
B88.1 is the ICD-10-CM diagnosis code for tungiasis [sandflea infestation]. An infestation by sand fleas (tungiasis), small parasitic fleas that burrow into the skin, typically affecting the feet and causing pain and inflammation. B88.1 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering pediculosis, acariasis and other infestations (b85-b89).
B88.1 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.
Document the anatomical site of infestation, as sand fleas typically affect lower extremities.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for B88.1 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Document the anatomical site of infestation, as sand fleas typically affect lower extremities
- •Note any secondary infections or complications from scratching or removal attempts
