Yes, but not with every insurance payor. Medicare and Medicare do not allow any negotiation. You can negotiate with many commercial payors. We have to analyze your rates first and compare with the local rates with a specific payor before proceeding with negotiation.
It varies by insurance payor but it may take anywhere between 4 weeks to 3 months. Some payors can take even up to 6 months. If you dont agree with their proposed rates, negotiating back and forth may even take up to 9-12 months.
There is no general rule but typically we recommend to negotiate the rates during the recredentialing process. You can negotiate during your initial credentialing application however some payors may not increase your rates.
