What must the county agency provide to a child's primary care physician to ensure coordination of medical care?

The requirement for the county agency to provide the identity of other medical practitioners treating the child serves a crucial purpose in ensuring effective and coordinated medical care. When multiple medical professionals are involved in a child's treatment, it is essential that they are aware of each other's roles and the specific treatments or interventions being administered. This information fosters communication among the various healthcare providers, which can prevent conflicting treatments and promote a holistic approach to the child's well-being.

In a scenario where multiple caregivers are involved, knowing who else is part of the child’s medical care enables the primary care physician to consult with specialists, share relevant information, and adjust treatment plans as necessary. This coordination is particularly important in cases of child abuse or neglect, where a comprehensive understanding of the child's medical history from all involved parties can significantly impact the child's safety and recovery.

The other choices, while they may seem relevant, do not address the specific need for coordination among caregivers. Medical history, costs associated with care, and contact information of parents, while important pieces of information, do not directly facilitate the integration of care among different medical practitioners as effectively as knowing their identities would.
