2014 ICD-9-CM Diagnosis Code 446.21
- ICD-9-CM 446.21 will be replaced by an equivalent ICD-10-CM code (or codes) when the United States transitions from ICD-9-CM to ICD-10-CM on October 1, 2015.
- ICD-9-CM 446.21 is a billable medical code that can be used to specify a diagnosis on a reimbursement claim.
- An autoimmune disease of the kidney and the lung. It is characterized by the presence of circulating autoantibodies targeting the epitopes in the non-collagenous domains of collagen type iv in the basement membranes of kidney glomeruli (kidney glomerulus) and lung alveoli (pulmonary alveoli), and the subsequent destruction of these basement membranes. Clinical features include pulmonary alveolar hemorrhage and glomerulonephritis.
- An autoimmune disorder characterized by pulmonary hemorrhage and glomerulonephritis. It is a hypersensitivity reaction resulting in the formation of antibodies against the pulmonary alveoli and the basement membrane of the glomeruli.
- An autoimmune disorder characterized by the production of autoantibodies against type iv collagen of the glomerular basement membrane of the kidney. In the majority of patients the immune reaction also extends to the alveolar capillary membrane of the lungs. The latter cases are referred to as goodpasture syndrome.
- Combination of pulmonary hemorrhage and glomerulonephritis; known also as the lung purpura glomerulonephritis complex; considered by some to be a form of hypersensitivity reaction.
- Antiglomerular basement membrane antibody-mediated nephritis with pulmonary hemorrhage
- Use additional code to identify renal disease (583.81)
