ICD-10 code for desert fever

The ICD-10-CM code for desert fever is B38.0 (Acute pulmonary coccidioidomycosis).

Within B38 (coccidioidomycosis), B38.0 is specifically for acute pulmonary coccidioidomycosis. Related codes cover chronic pulmonary coccidioidomycosis (B38.1), pulmonary coccidioidomycosis, unspecified (B38.2), cutaneous coccidioidomycosis (B38.3), meningitis (B38.4), disseminated coccidioidomycosis (B38.7), other forms of coccidioidomycosis (B38.8) and unspecified (B38.9).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 177 (Respiratory Infections and Inflammations with MCC, relative weight 1.6092), DRG 178 (Respiratory Infections and Inflammations with CC, relative weight 0.9744), DRG 179 (Respiratory Infections and Inflammations without CC/MCC, relative weight 0.7345), DRG 974 (HIV with Major Related Condition with MCC, relative weight 3.0506), DRG 975 (HIV with Major Related Condition with CC, relative weight 1.3252) and DRG 976 (HIV with Major Related Condition without CC/MCC, relative weight 0.8124), in MDC 04 (Diseases and Disorders of the Respiratory System) and MDC 25 (Human Immunodeficiency Virus Infections), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
