Definition of Medical Treatment Case

A medical treatment case (MTC) is a work-related injury or illness that requires medical treatment beyond first aid, but does not result in a fatality, days away from work, restricted work or job transfer. In the United States, a case involving medical treatment beyond first aid is recordable on the OSHA 300 log, even if the worker returns to normal duties right away.

Medical treatment cases are one of the main categories in injury reporting and are counted in the total recordable incident rate (TRIR). Many organizations also track them separately as a sign of injuries that were more than minor but did not cause lost time.

Under OSHA's recordkeeping rule, 29 CFR 1904.7, medical treatment means the management and care of a patient to combat disease or disorder. It does not include visits to a doctor or nurse solely for observation or counseling, diagnostic procedures such as X-rays and blood tests, or anything on OSHA's first aid list.

Medical Treatment vs First Aid

Examples of first aid (not recordable on their own)

  • Non-prescription medication at non-prescription strength.
  • Cleaning, flushing or soaking surface wounds.
  • Bandages, gauze pads, butterfly bandages or Steri-Strips.
  • Hot or cold therapy.
  • Non-rigid supports such as elastic bandages and wraps.
  • Removing splinters or foreign bodies from the eye by simple means such as irrigation or a cotton swab.
  • Tetanus immunizations.
  • Drinking fluids for heat stress.

Examples of medical treatment (recordable)

  • Prescription medication, or non-prescription medication recommended at prescription strength.
  • Sutures, staples or surgical glue to close wounds.
  • Rigid devices for immobilization, such as casts or splints with rigid stays.
  • Physical therapy or chiropractic treatment.
  • Removing foreign bodies from the eye using tools or by a physician.
  • Removing embedded foreign bodies by means other than simple tools.

A case is recordable based on what treatment was provided or recommended by a licensed health care professional, not on who provided it. If a doctor recommends prescription medication and the worker chooses not to take it, the case is still recordable.

Managing Medical Treatment Cases

  • Report all injuries promptly so they can be assessed and recorded correctly.
  • Investigate medical treatment cases to find root causes, since many could have been more serious.
  • Train supervisors and first aiders on the difference between first aid and medical treatment.
  • Never pressure workers or clinicians to avoid treatment to keep a case off the log.
  • Track MTCs alongside other measures such as incident rate and leading indicators.

Example of Medical Treatment Case

A warehouse worker cut his forearm on a sharp metal strap while opening a pallet. The site first aider cleaned the wound and applied a bandage, but the cut kept bleeding. The worker went to an urgent care clinic, where the doctor closed it with four stitches. He returned to his normal job the next day.

Because the cut needed sutures, the company recorded it on its OSHA 300 log as a medical treatment case. The investigation led the site to supply strap cutters and cut-resistant gloves at all receiving stations.

Frequently Asked Questions: Medical Treatment Case

Is a medical treatment case OSHA recordable?

Yes. Any work-related injury or illness requiring medical treatment beyond first aid is recordable, even without lost time.

Are diagnostic tests like X-rays considered medical treatment?

No. Diagnostic procedures alone, such as X-rays and blood tests, are not medical treatment under OSHA rules.

What is the difference between a medical treatment case and a lost time injury?

A medical treatment case needs care beyond first aid but the worker does not miss work. A lost time injury results in the worker missing at least one full scheduled shift after the injury day.
