2022 ICD-10-CM Code B64
Unspecified protozoal disease
Valid for Submission
| ICD-10: | B64 |
| Short Description: | Unspecified protozoal disease |
| Long Description: | Unspecified protozoal disease |
Code Classification
B64 is a billable diagnosis code used to specify a medical diagnosis of unspecified protozoal disease. The code B64 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code B64 might also be used to specify conditions or terms like dilated cardiomyopathy secondary to infection, dilated cardiomyopathy secondary to protozoal myocarditis, encephalitis due to protozoa, infective esophagitis, infective ulcer of esophagus , parasitic disease in mother complicating pregnancy, childbirth and/or puerperium, etc.
Unspecified diagnosis codes like B64 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code B64 is grouped in the following groups for version MS-DRG V39.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2021 through 09/30/2022.
| MS-DRG | MS-DRG Title | MCD | Relative Weight |
|---|---|---|---|
| 867 | OTHER INFECTIOUS AND PARASITIC DISEASES DIAGNOSES WITH MCC | 18 | 2.2295 |
| 868 | OTHER INFECTIOUS AND PARASITIC DISEASES DIAGNOSES WITH CC | 18 | 1.0584 |
| 869 | OTHER INFECTIOUS AND PARASITIC DISEASES DIAGNOSES WITHOUT CC/MCC | 18 | 0.726 |
The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.
Convert B64 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code B64 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Information for Patients
Parasitic Diseases
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.
Parasites range in size from tiny, one-celled organisms called protozoa to worms that can be seen with the naked eye. Some parasitic diseases occur in the United States. Contaminated water supplies can lead to Giardia infections. Cats can transmit toxoplasmosis, which is dangerous for pregnant women. Others, like malaria, are common in other parts of the world.
If you are traveling, it's important to drink only water you know is safe. Prevention is especially important. There are no vaccines for parasitic diseases. Some medicines are available to treat parasitic infections.
