When can physicians begin to order observation services according to CMS?

Physicians can order observation services according to CMS once they have seen and evaluated the patient. This requirement ensures that the physician understands the patient's condition and medical needs before making decisions about observation services. The evaluation allows the physician to assess the patient's symptoms and determine whether the observation status is appropriate, rather than simply relying on admission or consent without a proper assessment.

Ordering observation services without an evaluation can lead to inappropriate use of resources or misclassification of a patient’s condition. It is crucial for patient safety and the appropriate alignment of necessary care with appropriate billing practices that a physician has firsthand knowledge of the patient's clinical situation before proceeding with observation orders. This practice is consistent with the goals of providing high-quality care and maintaining compliance with regulatory requirements.
