Cystic fibrosis with pulmonary manifestations

This code identifies cystic fibrosis (CF) specifically when the patient exhibits pulmonary involvement. CF is a genetic disorder that primarily affects the lungs, leading to the production of thick, sticky mucus that obstructs airways and predisposes to chronic infections and inflammation. Pulmonary manifestations are a hallmark of CF and are often the most significant cause of morbidity and mortality.

Assign this code for patients diagnosed with cystic fibrosis who present with any pulmonary symptoms or signs, such as chronic cough, recurrent respiratory infections, bronchiectasis, or obstructive lung disease. Documentation should clearly state a diagnosis of cystic fibrosis and indicate the presence of lung involvement, even if mild.

• Always sequence this code first when the pulmonary manifestations are the primary reason for the encounter.
• Do not use this code if the patient has cystic fibrosis but only extrapulmonary manifestations are documented (e.g., pancreatic insufficiency without lung involvement).
• Code additional specific pulmonary conditions, such as bronchiectasis (J47.-) or recurrent pneumonia (J18.9), as secondary diagnoses to further describe the patient's clinical picture.
