ICD-10-CM Code For Unspecified Protozoal Disease: Group Overview
The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group B64 includes nonspecific protozoal infections where the causative protozoan or the clinical syndrome is not identified, covering systemic and organ-specific presentations attributable to protozoa. These ICD-10-CM diagnosis codes are used to document clinical encounters where a protozoal infection is diagnosed but the organism or precise clinical manifestation remains unspecified, capturing disease severity or extent when specific codes are not applicable. Accurate coding within the ICD-10-CM B64 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

ICD-10-CM B64: Unspecified Protozoal Disease Overview
The ICD-10-CM B64 group represents diagnoses for protozoal infections not specified to a particular organism or clinical syndrome, generally affecting multiple organ systems depending on the pathogen and host response. These conditions target infectious disease processes caused by single-celled eukaryotic organisms and may involve gastrointestinal, hepatic, neurologic, or systemic manifestations. Accurate coding is important for complete clinical documentation and can affect reimbursement and public health surveillance.
