2026 ICD-10-CM Diagnosis Code A15.9Respiratory tuberculosis unspecified

AHRQ’s CCSR groups this code into broader clinical categories.

• 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.

• 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.

• 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, Oral

  tuberculosis of the mouth, tongue, and salivary glands.

• Tuberculosis, Osteoarticular

  tuberculosis of the bones or joints.

• Tuberculosis, Pleural

  tuberculosis of the serous membrane lining the thoracic cavity and surrounding the lungs.

• 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.

• 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.

• Mycobacterium bovis

  the bovine variety of the tubercle bacillus. it is called also mycobacterium tuberculosis var. bovis.

• 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.

• Tuberculous Abscess

  an abscess resulting from infection by mycobacterium tuberculosis.

Tuberculosis

Tuberculosis (TB) is a bacterial disease that usually attacks the lungs. But it can also attack other parts of the body, including the kidneys, spine, and brain.
