Which of the following is NOT part of the HIM department's collaboration with patient registration?

The choice of assigning medical codes for services is not part of the HIM department's direct collaboration with patient registration. The primary role of patient registration focuses on collecting and verifying patient demographic information, which includes ensuring the accuracy and quality of this data. This process helps establish a patient’s record in the healthcare system.

Collaborating on the master patient index is critical, as inaccuracies in this index can lead to duplicate records or misidentification of patients. This is essential for effective patient management and continuity of care.

Ensuring the quality of the data collected during registration is vital, as it impacts clinical care, billing, and compliance with regulations. HIM professionals work closely with patient registration to ensure that demographic data is not only captured but also accurate.

While medical coding is an essential function within the HIM department, it occurs after patient registration has taken place. Medical coding involves translating healthcare services into standardized codes for billing and record-keeping support, and thus happens after the registration process is completed. Therefore, it does not involve direct collaboration with the patient registration team.
