McKesson hires for a range of work at home jobs in the United States and Canada. Job titles may include Telehealth Registered Nurse, Medical Coder and more.
Remote appears to be the best keyword to find work at home positions, but not perfect. Some will require extensive travel. Not all jobs with "Remote" in their titles will be home based. "Work at home" may also be worth a try, but it still gets a lot of jobs that are not home based. You will need to read any interesting job postings carefully to decide if it is in fact a work at home job.
