McKesson EthicsLine

McKesson has established a toll-free EthicsLine, available 24-hours a day, 7 days a week, which can be used to report violations of the Company's policies or other possible illegal or unethical activity, including concerns relating to accounting, internal accounting controls or auditing matters. Your call will be answered by a third-party communication specialist who is trained to handle your call and forward it to the Company appropriately and confidentially.

The McKesson EthicsLine can be reached at 1.888.475.4358.
