Health First, an integrated Rockledge, Fla., health system, plans to acquire Melbourne (Fla.) Internal Medicine Associates, a multispecialty physician practice.

Financial terms of the deal were not disclosed. Health First said in a news release that it plans to combine the new practice with its existing physician group and rename the entity Health First Medical Group. It will have a total of 250 physicians who will work in a number of locations, according to the release.

The transaction is subject to regulatory approval, but Health First said it expects Health First Medical Group to begin operating in February. The full integration is expected to take 18 to 24 months, and the system is working with a strategic consulting firm to aid in the transition process, it noted.
