I suggest you review the Cystic Fibrosis Foundation Guidelines for more information on what to expect or request at your Clinic. In particular, I am pasting the Guideline regarding the use if masks by CF patients at all facilities - regardless of whether anY other patients wear a mask.
21. The CF Foundation recommends that all people with CF wear a surgical (procedure, isolation) mask when in a healthcare facility to reduce the risk of transmission or acquisition of CF pathogens. Masks should be worn throughout the facility, including in restrooms. Masks should not be worn during pulmonary function testing, in the clinic exam room, or in the patient’s hospital room. If the optimal size mask is not available (eg, for small infants), use the smallest mask available. If a mask is not tolerated by an individual with CF who is having respiratory distress, encourage that person to follow Respiratory Hygiene practices. Masks should be changed when wet.
Source of supporting evidence: 2007 transmission guideline, Category IB
2013 CF IP&C guideline consensus: 100%
Here's a link to the Guidelines in toto.
