2014 ICD-9-CM Diagnosis Code 273.4
- Short description: Alpha-1-antitrypsin def.
- ICD-9-CM 273.4 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 273.4 is a billable medical code that can be used to specify a diagnosis on a reimbursement claim.
- Alpha 1 antitrypsin deficiency
- A genetic disorder characterized by decreased alpha-1 antitrypsin activity in the lungs and blood and deposition of alpha-1 antitrypsin protein in the hepatocytes. These abnormalities result from defective production of alpha-1 antitrypsin and lead to the development of emphysema, cirrhosis, and liver failure.
- Alpha-1 antitrypsin deficiency is an inherited disorder that can cause lung disease in adults and liver disease in adults and children. Alpha-1 antitrypsin (aat) is a protein that protects the lungs. The liver usually makes the protein, and releases it into the bloodstream. Because of a gene problem, some people have little or none of it. Not having enough aat puts you at risk of emphysema or liver problems. If you smoke, you increase your risk. Children with aat deficiency can develop liver problems that last their whole lives. Aat deficiency can be treated but not cured. One treatment involves adding to or replacing the missing protein. A lung transplant may be an option if you are seriously ill. Staying away from cigarette smoke is crucial.a blood test can tell if you have the deficiency. If you have it, your family members should also take the blood test.
- Autosomal recessive trait leading to destruction of lung tissue by neutrophil elastase and eventual emphysema; second only to cystic fibrosis as most common lethal genetic disorder among caucasians of northern european ancestry.
- Deficiency of the protease inhibitor alpha 1-antitrypsin that manifests primarily as pulmonary emphysema and liver cirrhosis.
