Which documents record healthcare services provided to a patient and include their treatment history?

Medical records are essential documents that capture a comprehensive record of healthcare services provided to a patient. They include details such as treatment history, diagnoses, treatment plans, and the results of examinations and tests. These records are vital for continuity of care, enabling healthcare providers to make informed decisions based on patients' prior treatments and conditions. Furthermore, they serve important roles in billing and insurance claims, as they provide the necessary evidence to support the medical services rendered.

The other options do not serve this specific purpose. Medical coverage refers to the type of insurance and what health services it will pay for but does not detail individual treatment histories. Medical necessity is a concept that dictates whether a service is deemed appropriate, reasonable, and necessary for a patient’s condition, but it doesn’t detail the actual services provided or the patient's treatment history. Diagnosis-related groups pertain to a system for classifying hospital cases for billing purposes but do not encompass individual patient treatment histories or records. Thus, the correct answer is clearly rooted in the definition of medical records.
