PROVIDENCE, R.I. (AP) — The estimated cost of Rhode Island's benefits computer system for benefits has grown by $150 million after state officials added an additional year's spending to the forecast.

WPRI-TV reports the latest estimate puts the total cost of the Unified Health Infrastructure Project at $647 million through the 2019-20 federal fiscal year, with $138 million covered by state taxpayers and the rest by the federal government.

The station reported the total projected budget is up from $492 million under the previous budget request. That did not include 2019-20 federal fiscal year.

The proposal must still be approved.

The UHIP system was supposed to streamline benefits programs including Medicaid, food stamps, and HealthSource RI. State officials have been struggling to fix it since it went live in September 2016.
