Cystic Fibrosis
Description of Cystic Fibrosis Cystic fibrosis, also known as mucoviscidosis or cystic fibrosis of the pancreas, is a disorder of the exocrine glands that causes accumulation of very thick, tenacious mucus and abnormal concentrations of sodium and chloride in sweat and saliva. Diagnosis is made by an elevated sweat-chloride test. The complications that occur in cystic fibrosis are primarily due to the thick mucus. Cystic fibrosis is the most common cause of life-threatening pulmonary disease in the white population during childhood and adolescence. It is the primary cause of pancreatic deficiency and chronic malabsorption in children. Between five and...

Article Overview
This article explains cystic fibrosis from a clinical and coding perspective, with emphasis on body systems affected, common complications, prognosis, and hospital diagnosis sequencing considerations. It is aimed at coders, CDI staff, and other healthcare professionals who need to understand how the condition is discussed in coding guidance and related reference material. The article also notes a Coding Clinic reference and includes examples of how cystic fibrosis is addressed in admission coding context without providing full premium guidance.
Why This Topic Matters
Cystic fibrosis is a complex chronic condition with multiple organ-system manifestations and frequent complications, so accurate documentation review and diagnosis sequencing are important for coding quality and record consistency.
