Bursitis may be covered under workers’ compensation when it is caused or aggravated by job duties, such as repetitive kneeling, lifting, reaching, or prolonged pressure on a joint. Medical evidence is important to connect the condition to your work. If the insurer disputes causation, an attorney can help gather records, job-duty evidence, and physician opinions.
