FAQ

Occupational Medicine Tool FAQs

What occupational medicine services do Tampa Bay employers usually need?

Most employers need a mix of pre-employment physicals, drug testing, DOT physicals for regulated drivers, respirator clearance or fit testing for exposed roles, OSHA documentation, injury evaluation, and return-to-work support.

Can occupational medicine be set up as an employer program instead of one-off visits?

Yes. Castellan Health can help employers standardize ordering, scheduling, documentation, and communication so HR, safety, and operations teams have a repeatable workforce health workflow.

How should employers estimate occupational medicine costs?

Useful cost planning starts with employee count, annual hiring volume, DOT driver count, safety-sensitive roles, respirator users, expected drug testing volume, and likely injury visits. A custom employer quote is still needed for final pricing.
