Which element is not commonly found in patient health records?

In the context of patient health records, the invoice for services is generally not included as a core component of the clinical documentation. Patient health records primarily focus on clinical information necessary for patient care and medical history, including identifying information, clinical history, and test results that facilitate diagnosis, treatment, and ongoing healthcare management.

Patient identification serves to uniquely distinguish individuals within the healthcare system, which is crucial for maintaining accurate records and ensuring patient safety. The clinical history provides insights into the patient's past medical conditions, treatments, and responses to these treatments, which are vital for current clinical assessments. Test results document the outcomes of diagnostic procedures and are essential for informed decision-making regarding patient care.

In contrast, invoicing is more related to the administrative and financial aspects of healthcare services rather than the clinical data required for a health record. Therefore, it is appropriate to identify the invoice for services as the element not commonly found in patient health records.
