No. Sending your employee to the company clinic does not automatically ruin the case.

From the insurance company's perspective, this is what they want everyone to believe: the first clinic note is the whole story, the injury was minor, and any later MRI, specialist referral, or surgery recommendation is just "treatment creep." If the company clinic in Great Falls wrote "strain," "return to work," or noted an old back problem, the carrier will use that to argue the crash on 10th Avenue South, I-15, or a roadwork lane shift did not cause much harm.

They also like a treatment gap. If your employee waited a week or two because it was construction season, jobs were active, or they tried to work through it, the insurer may say the later symptoms came from something else.

Reality is different.

In Montana, the first visit matters, but it does not lock the case forever. A worker can still have a real injury that shows up more clearly days later, especially with neck, shoulder, back, or concussion symptoms after a crash involving heavy equipment, flaggers, or a sudden lane change. Wind, trailer sway, and work-zone collisions around Great Falls often produce delayed pain.

What helps now is damage control:

• Make sure the injury was reported within 30 days for workers' comp purposes.
• Get follow-up care if symptoms continued or worsened.
• Make sure the later provider has the first clinic records, crash details, and job duties.
• Document any missed work, lifting limits, and why treatment was delayed.
• If there is a third-party claim against another driver or contractor, Montana's general filing deadline is 3 years.

If the insurer schedules an IME, treat it like a defense exam, not regular treatment. The IME doctor is usually there to evaluate for the carrier, not to manage care.
