A30.2 is a billable diagnosis code used to specify a medical diagnosis of borderline tuberculoid leprosy. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Borderline leprosy
  • Borderline tuberculoid leprosy

Clinical Classification

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, 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.
  • 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, 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.
  • Mycobacterium leprae

    a species of gram-positive, aerobic bacteria that causes leprosy in man. its organisms are generally arranged in clumps, rounded masses, or in groups of bacilli side by side.

Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

Index to Diseases and Injuries References

The following annotation back-references for this diagnosis code are found in the injuries and diseases index. The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10-CM code(s).

Convert A30.2 to ICD-9-CM

  • ICD-9-CM Code: 030.3 - Borderline leprosy
    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education

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.

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
