Does there need to be a separate treatment plan to meet the plan of care requirements within the Comprehensive Manual for Behavior Health Care and Human Services (BHC)?

Any examples are for illustrative purposes only.

No, how the plan of care is documented in the medical record is up to each organization.  A treatment plan is not referring to a particular document rather the process to plan and implement coordinated, client-centered care. Some organizations have chosen to create a plan of care template/document. However, each element of the individual's treatment plan, as reflected in The Joint Commission requirements, may be incorporated in various aspects of the medical record such as progress notes. Compliance will be assessed per organization policies/procedures.
