Although two states recently announced that they are taking a close look at Aetna Inc.’s practices for denying claims for health care coverage, the scrutiny is unlikely to prevent the insurance giant’s proposed merger with CVS Health from going through, corporate lawyers said.

California Insurance Commissioner Dave Jones announced Monday the opening of an investigation into Aetna’s claims denial process, its requests for prior authorization for care, and its utilization review process. Later that afternoon, Colorado Interim Insurance Commissioner Michael Conway said that his office would be making inquiries about whether Aetna’s procedure for appealing the denial of coverage for a medical procedure complies with Colorado law governing the issue.
