Approximate Synonyms

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

  • Borderline leprosy
  • Midborderline 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.

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


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.
  • BB leprosy

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 A30.3 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.

Leprosy

Leprosy, also called Hansen disease, is a disorder known since ancient times. It is caused by bacteria called Mycobacterium leprae and is contagious, which means that it can be passed from person to person. It is usually contracted by breathing airborne droplets from affected individuals' coughs and sneezes, or by coming into contact with their nasal fluids. However, it is not highly transmissible, and approximately 95 percent of individuals who are exposed to Mycobacterium leprae never develop leprosy. The infection can be contracted at any age, and signs and symptoms can take anywhere from several months to 20 years to appear.

Leprosy affects the skin and the peripheral nerves, which connect the brain and spinal cord to muscles and to sensory cells that detect sensations such as touch, pain, and heat. Most affected individuals have areas of skin damage (cutaneous lesions) and problems with nerve function (peripheral neuropathy); however, the severity and extent of the problems vary widely. Leprosy occurs on a spectrum, in which the most severe form is called multibacillary or lepromatous, and the least severe form is called paucibacillary or tuberculoid. Patterns of signs and symptoms intermediate between these forms are sometimes called borderline forms.

Multibacillary leprosy usually involves a large number of cutaneous lesions, including both surface damage and lumps under the skin (nodules). The moist tissues that line body openings such as the eyelids and the inside of the nose and mouth (mucous membranes) can also be affected, which can lead to vision loss, destruction of nasal tissue, or impaired speech. Some affected individuals have damage to internal organs and tissues. The nerve damage that occurs in multibacillary leprosy often results in a lack of sensation in the hands and feet. Repeated injuries that go unnoticed and untreated because of this lack of sensation can lead to reabsorption of affected fingers or toes by the body, resulting in the shortening or loss of these digits.

Paucibacillary leprosy typically involves a small number of surface lesions on the skin. There is generally loss of sensation in these areas, but the other signs and symptoms that occur in multibacillary leprosy are less likely to develop in this form of the disorder.

In any form of leprosy, episodes called reactions can occur, and can lead to further nerve damage. These episodes can include reversal reactions, which involve pain and swelling of the skin lesions and the nerves in the hands and feet. People with the more severe forms of leprosy can develop a type of reaction called erythema nodosum leprosum (ENL). These episodes involve fever and painful skin nodules. In addition, painful, swollen nerves can occur. ENL can also lead to inflammation of the joints, eyes, and the testicles in men.

Leprosy has long been stigmatized because of its infectious nature and the disfigurement it can cause. This stigma can cause social and emotional problems for affected individuals. However, modern treatments can prevent leprosy from getting worse and spreading to other people. While the infection is curable, nerve and tissue damage that occurred before treatment is generally permanent.

Footnotes

[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.
