Guidelines for clinical documentation of evaluation and management face-to-face services were developed over 20 years ago. Recently, the Centers for Medicare and Medicaid Services (CMS) have addressed office and other outpatient services and the corresponding reimbursement, intending to reduce the amount of required documentation and to alleviate clerical burden. A CMS final rule for 2021 will eliminate the history and physical examination as criteria for level of service, allow time or medical decision making to be used as coding criteria, and will recognize a code for prolonged service. The net effect of these changes may be some decrease in documentation burden, a change in the composition of clinical notes, and greater recognition by CMS of primary care and those who see highly complex patients requiring prolonged services.
