About coding congenital tuberculosis
The ICD-10-CM code for congenital tuberculosis is P37.0 (Congenital tuberculosis).
Within P37 (other congenital infectious and parasitic diseases), P37.0 is specifically for congenital tuberculosis. Related codes cover congenital toxoplasmosis (P37.1), neonatal (disseminated) listeriosis (P37.2), congenital falciparum malaria (P37.3), other congenital malaria (P37.4), neonatal candidiasis (P37.5), other specified congenital infectious and parasitic diseases (P37.8) and congenital infectious or parasitic disease, unspecified (P37.9).
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 791 (Prematurity with Major Problems, relative weight 4.1075) and DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), in MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
