How to Escalate a McKesson Complaint
The following are suggested steps, rather than a published company-wide complaint procedure:
- Start with the responsible business unit. Use Medical-Surgical support for supply orders and the appropriate pharmaceutical team for drug-distribution accounts.
- Prepare the relevant records. Have your account number, order or invoice number, delivery date and previous case reference available. For a product issue, include the item and lot number when relevant.
- Explain the resolution you are requesting. For example, ask for an order-status investigation, billing review or return instructions.
- Request further review if unresolved. Ask the support representative to involve a supervisor or your account representative. Keep the case number and agreed follow-up details.
- Use corporate routing when needed. If you cannot identify the responsible department, contact headquarters and request direction to the appropriate business unit.
A COH review does not submit a complaint or service request to McKesson. Contact the relevant department directly for action on an account or order.
