Pennsylvania Workers’ Comp (2025): Statute, Deadlines & Appeals
If you’re hurt at work in Pennsylvania, timing rules decide whether benefits are paid. Within 21 days of employer notice, a carrier must accept/deny or start temporary benefits, and missing the 120-day notice window can bar a claim altogether.
This 2025 guide covers notice windows & filing timelines, medical-proof rules (including the 90-day provider list), wage-loss math (e.g., $1,347 maximum weekly rate in 2025), the appeals ladder, and common mistakes to avoid.

Notice windows
- Report ASAP: Tell your employer as soon as you suspect a work-related injury.
- 21 days: Report within 21 days to preserve retroactive pay from the injury date.
- 120 days: Notice after 120 days generally bars compensation.
Filing timelines
The Claim Petition deadline is 3 years from the injury date (Section 315). For occupational disease: disability must occur within 300 weeks of last exposure and the petition must be filed within 3 years of disability.
