Maryland Workers' Compensation: 10‑Day Injury Reporting Rule Explained

Reporting Deadline in Maryland

Employers must receive notice of a work‑related injury or illness within ten calendar days of the employee's knowledge of the incident. This ten‑day rule is stricter than the federal OSHA 24‑hour notice for severe injuries and the typical 30‑day claim filing window, making timely communication essential in Maryland.

Why the Ten‑Day Rule Exists

The short window helps the Maryland Workers' Compensation Commission (MWCC) verify claims while evidence is fresh, reduces fraudulent reporting, and ensures prompt medical care. Missing the deadline does not automatically bar a claim, but it can lead to delays, reduced benefits, or a requirement for the employee to prove why notice was late.

Steps to Comply

Follow these actions to satisfy the ten‑day requirement:

• Immediately inform your supervisor or designated safety officer of the injury.
• Document the incident in writing, noting date, time, location, and circumstances.
• Submit the written notice to the employer's HR or workers' comp administrator within ten days.
• Request a copy of the employer's written acknowledgment for your records.

Employer Responsibilities

Once the employer receives the notice, they must:

• Complete the MWCC Form 1 (Employer's First Report of Injury) and submit it to the Commission within ten days of receipt.
• Provide the employee with a copy of the completed Form 1.
• Arrange for appropriate medical treatment, either through a designated provider or the employee's choice, depending on the employer's policy.

Consequences of Late Reporting

If the ten‑day deadline is missed, the MWCC may:

• Delay claim processing while investigating the reason for lateness.
• Reduce or deny temporary disability benefits if the delay suggests the injury was not work‑related.
• Require the employee to submit a written explanation and supporting evidence for the missed deadline.

Common Exceptions

Certain situations can extend the reporting period, such as:

• Delayed symptom onset that prevents the employee from recognizing the injury until after ten days.
• Injuries sustained in a remote work setting where the employer's reporting channel is unclear.

Practical Tips for Mobile Users

Since many workers rely on smartphones to report incidents, ensure the employer's reporting system is mobile‑friendly. Use voice‑to‑text features to quickly capture details, take timestamped photos of the injury site, and store the digital notice in a cloud folder for easy retrieval.
