Specific Coding for Other congenital infectious and parasitic diseasesOverview

Non-specific codes like P37 require more characters. Use one of these billable codes instead:

  • Use P37.0 for Congenital tuberculosis

  • Use P37.1 for Congenital toxoplasmosis

  • Use P37.2 for Neonatal (disseminated) listeriosis

  • Use P37.3 for Congenital falciparum malaria

  • Use P37.4 for Other congenital malaria

Infectious Diseases

Germs, or microbes, are found everywhere - in the air, soil, and water. There are also germs on your skin and in your body. Many of them are harmless, and some can even be helpful. But some of them can make you sick. Infectious diseases are diseases that are caused by germs.
