Before You Commit

Typical timing is walk-in at many clinics; book ahead for group testing. Ask:

• Do you treat work injuries, and do you bill workers’ compensation directly?
• Is a certified medical examiner on staff for DOT physicals?
• Do you offer respirator medical evaluations and fit tests?
• Do you offer audiograms and lung function tests?
• How fast do employers get results?

Tips

• Set up the employer account before you have an injury, so workers know where to go.
• DOT physicals must be done by an examiner on the FMCSA National Registry.
• Workers’ compensation rules on choosing a doctor vary by state, so check yours.
