Does Massachusetts have a workers' compensation fee schedule?

Excuse me, could you please clarify if Massachusetts has a specific fee schedule in place for workers' compensation claims? I'm trying to understand the financial implications for employees who may be injured on the job and how the state regulates the compensation process. Is there a standardized rate or a range of fees that apply, or does it vary based on the nature of the injury or other factors? Thank you for your assistance in clarifying this matter.
