Human immunodeficiency virus [HIV] disease B20-

Use Additional
Use Additional Help
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation. In most cases the manifestation codes will have in the code title, "in diseases classified elsewhere." Codes with this title are a component of the etiology/manifestation convention. The code title indicates that it is a manifestation code. "In diseases classified elsewhere" codes are never permitted to be used as first listed or principle diagnosis codes. They must be used in conjunction with an underlying condition code and they must be listed following the underlying condition.

A type 1 excludes note is a pure excludes. It means "not coded here". A type 1 excludes note indicates that the code excluded should never be used at the same time as B20. A type 1 excludes note is for used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Information
  • A disease caused by human immunodeficiency virus (hiv). People with acquired immunodeficiency syndrome are at an increased risk for developing certain cancers and for infections that usually occur only in individuals with a weak immune system.
  • A prodromal phase of infection with the human immunodeficiency virus (hiv). Laboratory criteria separating aids-related complex (arc) from aids include elevated or hyperactive b-cell humoral immune responses, compared to depressed or normal antibody reactivity in aids; follicular or mixed hyperplasia in arc lymph nodes, leading to lymphocyte degeneration and depletion more typical of aids; evolving succession of histopathological lesions such as localization of kaposi's sarcoma, signaling the transition to the full-blown aids.
  • A syndrome resulting from the acquired deficiency of cellular immunity caused by the human immunodeficiency virus (hiv). It is characterized by the reduction of the helper t-lymphocytes in the peripheral blood and the lymph nodes. Symptoms include generalized lymphadenopathy, fever, weight loss, and chronic diarrhea. Patients with aids are especially susceptible to opportunistic infections (usually pneumocystis carinii pneumonia, cytomegalovirus (cmv) infections, tuberculosis, candida infections, and cryptococcosis), and the development of malignant neoplasms (usually non-hodgkin's lymphoma and kaposi's sarcoma). The human immunodeficiency virus is transmitted through sexual contact, sharing of contaminated needles, or transfusion of contaminated blood.
  • An acquired defect of cellular immunity associated with infection by the human immunodeficiency virus (hiv), a cd4-positive t-lymphocyte count under 200 cells/microliter or less than 14% of total lymphocytes, and increased susceptibility to opportunistic infections and malignant neoplasms. Clinical manifestations also include emaciation (wasting) and dementia. These elements reflect criteria for aids as defined by the cdc in 1993.
  • An infection caused by the human immunodeficiency virus.
  • Any state of infection accompanied by evidence of hiv in the body (positive test for hiv genome, cdna, proteins, antigens, or antibodies); may be medically asymptomatic or symptomatic; use aids when appropriate.
  • Includes the spectrum of human immunodeficiency virus infections that range from asymptomatic seropositivity, thru aids-related complex (arc), to acquired immunodeficiency syndrome (aids).
  • One or more indicator diseases, depending on laboratory evidence of hiv infection (cdc); late phase of hiv infection characterized by marked suppression of immune function resulting in opportunistic infections, neoplasms, and other systemic symptoms (niaid).
