ICD-10 code for lung candidiasis

The ICD-10-CM code for lung candidiasis is B37.1 (Pulmonary candidiasis).

Within B37 (candidiasis), B37.1 is specifically for pulmonary candidiasis. Related codes cover Candidal stomatitis (B37.0), of skin and nail (B37.2), of vulva and vagina (B37.3), of other urogenital sites (B37.4), Candidal meningitis (B37.5), Candidal endocarditis (B37.6), Candidal sepsis (B37.7), of other sites (B37.8) and 1 more.

As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" 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 791 (Prematurity with Major Problems, relative weight 4.1075), DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), DRG 974 (HIV with Major Related Condition with MCC, relative weight 3.0506) and 2 more, in MDC 04 (Diseases and Disorders of the Respiratory System), MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period) 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.
