Clinical Information
  • Group of rare congenital disorders characterized by impairment of both humoral and cell-mediated immunity, leukopenia, and low or absent antibody levels; it is inherited as an x-linked or autosomal recessive defect; about half of the patients with autosomal recessive scid are deficient in the enzyme adenosine deaminase.
  • X-linked or autosomal recessive disorder characterized by defects of both humoral and cell mediated immunity, resulting in low or absent antibody levels, leukopenia, marked susceptibility to infections, and early death.

ICD-9-CM codes are used in medical billing and coding to describe diseases, injuries, symptoms and conditions. ICD-9-CM 279.2 is one of thousands of ICD-9-CM codes used in healthcare. Although ICD-9-CM and CPT codes are largely numeric, they differ in that CPT codes describe medical procedures and services. Can't find a code?
