Massachusetts provides up to 20 weeks of paid medical leave as long as you have a serious health condition, which is defined as "a physical or mental condition that prevents you from doing your job for more than 3 consecutive days." It requires at least one of the following:

• Overnight stay in a medical facility
• 2 or more treatments by a health care provider within 30 days of whatever prevented you from doing your job
• At least 1 treatment by a health care provider within 30 days of whatever prevented you from doing your job, with plans for continued treatment, including prescriptions

All of this is not taking into account additional benefits that may be provided like short/long term disability.
