During your recovery, your doctor or an insurance adjuster may use the term “Maximum Medical Improvement,” or MMI. For many injured workers in Des Moines, this phrase can cause confusion and alarm.
It sounds like a confirmation that you healed fully. However, in the workers’ compensation system, MMI simply means your condition stabilized and will likely not improve significantly with further treatment.
It does not mean a full cure
Reaching MMI does not guarantee a pain-free life or a return to 100% health. It means that, in the opinion of the authorized physician, additional surgery or physical therapy will not improve your injury further.
For a construction worker with a back injury or a factory worker with a shoulder strain, you might reach MMI while still battling permanent stiffness or chronic pain.
Why this milestone matters
This declaration represents a pivotal moment in your case because it typically signals the end of your temporary recovery benefits. According to Iowa workers’ compensation law, once a doctor declares MMI, the focus shifts from “healing” to assessing permanent damage.
Your doctor will likely assign an impairment rating. This rating helps calculate the future benefits you deserve for lasting disability.
The risk of early MMI
Disputes often arise when a company doctor declares a worker reached MMI before the worker feels ready. If the insurer rushes you to this stage, you could lose access to necessary treatments.
Protecting your future
If you disagree with a doctor’s finding of MMI, or if the resulting impairment rating seems too low given your inability to work, you have the right to challenge it. An experienced workers’ compensation attorney can help you secure a second opinion to ensure the records accurately reflect your medical reality.
