The group is pushing reports; polls; and advertisements opposing the cuts, which it says will deal a "crushing blow" to insurers and patients.
On Monday, AHIP touted the responses of several Medicare Advantage beneficiaries who feel the cuts would be destructive.
"Like most on the Medicare Advantage program, I am happy with my coverage and don’t want to see any more cuts that will lead to higher costs and reduced benefits for me," said Howard Brown of Centennial, Colo.
Medicare Advantage provides care for seniors that prefer to contract with private insurers while on Medicare.
Supporters of the cuts, along with government auditors, say Medicare overpays Medicare Advantage plans by billions of dollars.
