Amazon will reimburse staff in the US who travel for non-life threatening medical treatments.
The firm will pay up to $4,000 in travel expenses each year for treatments not available nearby, according to a message to Amazon staff.
Several companies have announced plans to make sure their staff have access to abortions.
There are rising restrictions for the procedure nationwide.
The new benefits are retroactive.
According to the announcement, the new benefits will apply to treatments that are not available inside a 100 mile (161 km) radius of an employee's home and for which virtual options are not available.
An Amazon spokesman confirmed the benefit expansion to the BBC and said it also includes in-patient substance abuse disorder services, congenital anomalies from within 24 months of birth, and mental health treatments.
One of the biggest private sector employers in the US is Amazon, with 1.1 million full and part-time workers. Most of its workers are in California, Texas and Washington state, which are home to its global headquarters.
The benefits will be available to all employees of the company, including those who work in offices or warehouses.
Up to $10,000 is offered for life-threatening medical issues.
While the expansion of benefits by Amazon is not aimed at allowing access to abortions, it comes at a time when several Republican state governments have passed laws limiting abortion access.
Next month, the Supreme Court will rule on a case that could overturn a court ruling that legalized abortion in the US.
More than 20 states are expected to limit abortion care or even ban abortions in most cases if the law is overturned.
A recent study found that some 1,400 Texans traveled out of state for abortions every month because of Texas' strict abortion laws.
Employees who travel to circumvent local abortion restrictions will be reimbursed by companies.
The policy was in response to changes in reproductive healthcare laws.
