Tenn. Code § 33-2-602
Every licensee under this title shall have a clear conflict resolution procedure, including an appeal process, that complies with the department's rules and shall communicate the procedure to each service recipient and family involved in the service. Termination of service or support because a third party payer refuses to continue to fund the service or support is not subject to the conflict resolution procedure. The location where service or support is to be provided is not subject to the conflict resolution procedure unless the location is inaccessible to the service recipient and the service recipient's family, as appropriate. The procedure must include the means to resolve a conflict informally and expeditiously in conformity with the department's rules.
