Michigan No-Fault Law, section by section › MCL 500.3158
Statement of earnings; report and records from medical institution.
In plain terms
On an insurer's request, an employer must furnish a sworn statement of the injured person's earnings before and after the injury, and providers must furnish written reports and allow inspection and copying of their treatment records.
How this section works in practice
The act gives PIP insurers direct access to the information they need to adjust a claim. On request, an employer must promptly furnish a sworn statement of the injured person's earnings before and after the injury, which is how work-loss benefits are calculated and verified. Physicians, hospitals, clinics and other medical institutions must furnish a written report of the history, condition, treatment, dates and costs of treatment, and must allow the insurer to inspect and copy the relevant records. The duty extends to treatment for other injuries and to conditions claimed to be connected with the accident, which is why insurers request records that predate the crash. Claimants should expect these requests and cooperate with them; refusing or delaying them slows payment, and a dispute over their scope is resolved by the court under section 3159.

(2) A physician, hospital, clinic or other medical institution providing, before or after an accidental bodily injury upon which a claim for personal protection insurance benefits is based, any product, service or accommodation in relation to that or any other injury, or in relation to a condition claimed to be connected with that or any other injury, if requested to do so by the insurer against whom the claim has been made, (a) shall furnish forthwith a written report of the history, condition, treatment and dates and costs of treatment of the injured person and (b) shall produce forthwith and permit inspection and copying of its records regarding the history, condition, treatment and dates and costs of treatment.
