Screening for cystic fibrosis

This code indicates a screening encounter performed to identify the potential presence of cystic fibrosis in an asymptomatic individual. It is used when a patient undergoes tests, such as a sweat chloride test or genetic screening, without exhibiting any signs or symptoms of the disease. The purpose is early detection in at-risk populations.

This code is appropriate for newborns undergoing routine screening for cystic fibrosis as part of state-mandated programs. It also applies to individuals undergoing genetic carrier screening for cystic fibrosis, particularly when there is a family history of the disease or during preconception counseling.

• Do not use this code if the patient is presenting with symptoms suggestive of cystic fibrosis; in such cases, use codes for diagnostic workup.
• Always code any definitive diagnosis of cystic fibrosis separately once confirmed.
• This code is for the screening encounter itself, not for the results of the screening.
