Respiratory tuberculosis (A15)

The ICD-10 codes in the A15 section are specifically used to classify various forms of respiratory tuberculosis, covering infections affecting the lungs, intrathoracic lymph nodes, pleura, and upper airways. These codes help identify tuberculosis conditions, including pulmonary tuberculosis, tuberculous pleurisy, and tuberculosis of the larynx, trachea, and bronchus.

This section includes codes for A15.0, which corresponds to tuberculosis of the lung; also known as pulmonary tuberculosis or infiltrative lung tuberculosis. Code A15.4 covers tuberculosis of the intrathoracic lymph nodes, often called tuberculous adenitis or hilar lymphadenopathy. Tuberculosis involving the larynx, trachea, and bronchus is coded as A15.5, sometimes referred to as tuberculous laryngitis or bronchopleural fistula. A15.6 is used for tuberculous pleurisy, which includes pleural effusions caused by tuberculosis bacteria. Primary respiratory tuberculosis, including acute and progressive forms, is classified under A15.7. Codes A15.8 and A15.9 capture other or unspecified respiratory tuberculosis types. These codes are essential for accurately documenting all manifestations of respiratory TB, including drug-resistant and histologically confirmed cases, ensuring clarity when coding for this infectious disease.

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Chylothorax

The presence of chyle in the thoracic cavity. (Dorland, 27th ed)

Erythema Induratum

A type of panniculitis characterized histologically by the presence of granulomas, vasculitis, and necrosis. It is traditionally considered to be the tuberculous counterpart of nodular vasculitis, but is now known to occur without tuberculous precedent. It is seen most commonly in adolescent and menopausal women, is initiated or exacerbated by cold weather, and typically presents as one or more recurrent erythrocyanotic nodules or plaques on the calves. The nodules may progress to form indurations, ulcerations, and scars.

Extensively Drug-Resistant Tuberculosis

Tuberculosis resistant to ISONIAZID and RIFAMPIN and at least three of the six main classes of second-line drugs (AMINOGLYCOSIDES; polypeptide agents; FLUOROQUINOLONES; THIOAMIDES; CYCLOSERINE; and PARA-AMINOSALICYLIC ACID) as defined by the CDC.

Hospitals, Chronic Disease

Hospitals which provide care to patients with long-term illnesses.

Hydrothorax

A collection of watery fluid in the pleural cavity. (Dorland, 27th ed)

Latent Tuberculosis

The dormant form of TUBERCULOSIS where the person shows no obvious symptoms and no sign of the causative agent (Mycobacterium tuberculosis) in the SPUTUM despite being positive for tuberculosis infection skin test.

Lupus Vulgaris

A form of cutaneous tuberculosis. It is seen predominantly in women and typically involves the NASAL MUCOSA; BUCCAL MUCOSA; and conjunctival mucosa.

Mycobacterium

A genus of gram-positive, aerobic bacteria. Most species are free-living in soil and water, but the major habitat for some is the diseased tissue of warm-blooded hosts.

Mycobacterium bovis

The bovine variety of the tubercle bacillus. It is called also Mycobacterium tuberculosis var. bovis.

Mycobacterium tuberculosis

A species of gram-positive, aerobic bacteria that produces TUBERCULOSIS in humans, other primates, CATTLE; DOGS; and some other animals which have contact with humans. Growth tends to be in serpentine, cordlike masses in which the bacilli show a parallel orientation.

Peritonitis, Tuberculous

A form of PERITONITIS seen in patients with TUBERCULOSIS, characterized by lesion either as a miliary form or as a pelvic mass on the peritoneal surfaces. Most patients have ASCITES, abdominal swelling, ABDOMINAL PAIN, and other systemic symptoms such as FEVER; WEIGHT LOSS; and ANEMIA.

Tuberculosis

Any of the infectious diseases of man and other animals caused by species of MYCOBACTERIUM TUBERCULOSIS.

Tuberculosis Societies

Voluntary agencies concerned with prevention and treatment of tuberculosis.

Tuberculosis Vaccines

Vaccines or candidate vaccines used to prevent or treat TUBERCULOSIS.

Tuberculosis, Avian

A variety of TUBERCULOSIS affecting various birds, including chickens and ducks. It is caused by MYCOBACTERIUM AVIUM and characterized by tubercles consisting principally of epithelioid cells.

Tuberculosis, Bovine

An infection of cattle caused by MYCOBACTERIUM BOVIS. It is transmissible to man and other animals.

Tuberculosis, Cardiovascular

Pathological conditions of the CARDIOVASCULAR SYSTEM caused by infection of MYCOBACTERIUM TUBERCULOSIS. Tuberculosis involvement may include the HEART; the BLOOD VESSELS; or the PERICARDIUM.

Tuberculosis, Central Nervous System

Tuberculosis of the brain, spinal cord, or meninges (TUBERCULOSIS, MENINGEAL), most often caused by MYCOBACTERIUM TUBERCULOSIS and rarely by MYCOBACTERIUM BOVIS. The infection may be limited to the nervous system or coexist in other organs (e.g., TUBERCULOSIS, PULMONARY). The organism tends to seed the meninges causing a diffuse meningitis and leads to the formation of TUBERCULOMA, which may occur within the brain, spinal cord, or perimeningeal spaces. Tuberculous involvement of the vertebral column (TUBERCULOSIS, SPINAL) may result in nerve root or spinal cord compression. (From Adams et al., Principles of Neurology, 6th ed, pp717-20)

Tuberculosis, Cutaneous

Tuberculosis of the skin. It includes scrofuloderma and tuberculid, but not LUPUS VULGARIS.

Tuberculosis, Endocrine

Infection of the ENDOCRINE GLANDS with species of MYCOBACTERIUM, most often MYCOBACTERIUM TUBERCULOSIS.

Tuberculosis, Extrapulmonary

MYCOBACTERIUM infections of organs other than the lung.

Tuberculosis, Female Genital

MYCOBACTERIUM infections of the female reproductive tract (GENITALIA, FEMALE).

Tuberculosis, Gastrointestinal

TUBERCULOSIS that involves any region of the GASTROINTESTINAL TRACT, mostly in the distal ILEUM and the CECUM. In most cases, MYCOBACTERIUM TUBERCULOSIS is the pathogen. Clinical features include ABDOMINAL PAIN; FEVER; and palpable mass in the ileocecal area.

Tuberculosis, Hepatic

Infection of the LIVER with species of MYCOBACTERIUM, most often MYCOBACTERIUM TUBERCULOSIS. It is characterized by localized small tuberculous miliary lesions or tumor-like mass (TUBERCULOMA), and abnormalities in liver function tests.

Tuberculosis, Laryngeal

Tuberculosis involving the larynx, producing ulceration of the VOCAL CORDS and the LARYNGEAL MUCOSA.

Tuberculosis, Lymph Node

Infection of the lymph nodes by tuberculosis. Tuberculous infection of the cervical lymph nodes is scrofula.

Tuberculosis, Male Genital

MYCOBACTERIUM infections of the male reproductive tract (GENITALIA, MALE).

Tuberculosis, Meningeal

A form of bacterial meningitis caused by MYCOBACTERIUM TUBERCULOSIS or rarely MYCOBACTERIUM BOVIS. The organism seeds the meninges and forms microtuberculomas which subsequently rupture. The clinical course tends to be subacute, with progressions occurring over a period of several days or longer. Headache and meningeal irritation may be followed by SEIZURES, cranial neuropathies, focal neurologic deficits, somnolence, and eventually COMA. The illness may occur in immunocompetent individuals or as an OPPORTUNISTIC INFECTION in the ACQUIRED IMMUNODEFICIENCY SYNDROME and other immunodeficiency syndromes. (From Adams et al., Principles of Neurology, 6th ed, pp717-9)

Tuberculosis, Miliary

An acute form of TUBERCULOSIS in which minute tubercles are formed in a number of organs of the body due to dissemination of the bacilli through the blood stream.

Tuberculosis, Multidrug-Resistant

Tuberculosis resistant to chemotherapy with two or more ANTITUBERCULAR AGENTS, including at least ISONIAZID and RIFAMPICIN. The problem of resistance is particularly troublesome in tuberculous OPPORTUNISTIC INFECTIONS associated with HIV INFECTIONS. It requires the use of second line drugs which are more toxic than the first line regimens. TB with isolates that have developed further resistance to at least three of the six classes of second line drugs is defined as EXTENSIVELY DRUG-RESISTANT TUBERCULOSIS.

Tuberculosis, Ocular

Tuberculous infection of the eye, primarily the iris, ciliary body, and choroid.

Tuberculosis, Pulmonary

MYCOBACTERIUM infections of the lung.

Tuberculosis, Renal

Infection of the KIDNEY with species of MYCOBACTERIUM.

Tuberculosis, Spinal

Osteitis or caries of the vertebrae, usually occurring as a complication of tuberculosis of the lungs.

Tuberculosis, Splenic

Infection of the spleen with species of MYCOBACTERIUM.

Tuberculosis, Urogenital

A general term for MYCOBACTERIUM infections of any part of the UROGENITAL SYSTEM in either the male or the female.
