Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code A30:

  • infection due to Mycobacterium leprae

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
  • sequelae of leprosy B92

Clinical Information

  • LEPROSY-. a chronic granulomatous infection caused by mycobacterium leprae. the granulomatous lesions are manifested in the skin the mucous membranes and the peripheral nerves. two polar or principal types are lepromatous and tuberculoid.
  • LEPROSY BORDERLINE-. a form of leprosy in which there are clinical manifestations of both principal types lepromatous and tuberculoid. the disease may shift toward one of these two polar or principal forms.
  • LEPROSY LEPROMATOUS-. a chronic communicable infection which is a principal or polar form of leprosy. this disorder is caused by mycobacterium leprae and produces diffuse granulomatous skin lesions in the form of nodules macules or papules. the peripheral nerves are involved symmetrically and neural sequelae occur in the advanced stage.
  • LEPROSY TUBERCULOID-. a principal or polar form of leprosy in which the skin lesions are few and are sharply demarcated. peripheral nerve involvement is pronounced and may be severe. unlike lepromatous leprosy leprosy lepromatous the lepromin test is positive. tuberculoid leprosy is rarely a source of infection to others.
  • LEPROSY PAUCIBACILLARY-. a form of leprosy classified by the world health organization for the purpose of treatment based on clinical manifestations and skin smear results. patients with paucibacillary leprosy have fewer than six skin lesions with no causative agent mycobacterium leprae on any slit skin smear testing. paucibacillary leprosy encompasses indeterminate borderline tuberculoid and tuberculoid leprosy.
  • LEPROSY MULTIBACILLARY-. a form of leprosy classified by the world health organization for the purpose of treatment based on clinical manifestations and skin smear results. patients with multibacillary leprosy have six or more lesions with or without positive skin smear results for the causative agent mycobacterium leprae. multibacillary leprosy encompasses borderline lepromatous midborderline and lepromatous leprosy.

Information for Patients

Mycobacterial Infections

Mycobacteria are a type of germ. There are many different kinds. The most common one causes tuberculosis. Another one causes leprosy. Still others cause infections that are called atypical mycobacterial infections. They aren't "typical" because they don't cause tuberculosis. But they can still harm people, especially people with other problems that affect their immunity, such as AIDS.

Sometimes you can have these infections with no symptoms at all. At other times, they can cause lung symptoms similar to tuberculosis:

  • Cough
  • Weight loss
  • Coughing up blood or mucus
  • Weakness or fatigue
  • Fever and chills
  • Night sweats
  • Lack of appetite and weight loss

Medicines can treat these infections, but often more than one is needed to cure the infection.
