About B38.3

B38.3 is the ICD-10-CM diagnosis code for cutaneous coccidioidomycosis. It belongs to category B38 (coccidioidomycosis), block B35-B49 (mycoses) and chapter 1 (certain infectious and parasitic diseases). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within B38 (coccidioidomycosis), B38.3 is specifically for cutaneous coccidioidomycosis. Related codes cover acute pulmonary coccidioidomycosis (B38.0), chronic pulmonary coccidioidomycosis (B38.1), pulmonary coccidioidomycosis, unspecified (B38.2), 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 606 (Minor Skin Disorders with MCC, relative weight 1.5728), DRG 607 (Minor Skin Disorders without MCC, relative weight 0.8772), 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 09 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast) 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.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 114.1 (primary extrapulmonary coccidioidomycosis).
