The text highlights how the guidelines differ, especially for psychiatry, and provides practical guidance on code selection, use in inpatient and outpatient settings, and flexibility when services are more medically oriented or involve counseling and care coordination.

Definitions and documentation requirements

4 Codes and Documentation for Evaluation and Management Services The evaluation and management (E/M) codes were introduced in the 1992 update to the fourth edition of Physicians’ Current Procedural Terminology (CPT) . These codes cover a broad range of services for patients in both inpatient and outpatient settings. In 1995 and again in 1997, the Health Care Financing Administration (now the Centers for Medicare and Medicaid Services, or CMS) published documentation guidelines to support the selection of appropriate E/M codes for services provided to Medicare beneficiaries. The major difference between the two sets of guidelines is that the 1997 set includes a single-system psychiatry examination (mental status examination) that can be fully substituted for the comprehensive, multisystem physical examination required by the 1995 guideline. Because of this, it clearly makes the most sense for mental health practitioners to use the 1997 guidelines (see Appendix E). A practical 27-page guide from CMS on how to use the documentation guidelines can be found at [http://www.cms.hhs.gov/MLNProducts/downloads/eval_mgmt_serv](http://www.cms.hhs.gov/MLNProducts/downloads/eval_mgmt_serv)[_guide.pdf. The American Medical Association](_guide.pdf. The American Medical Association)’[s](s) CPT manual also provides valuable information in the introduction to its E/M section. Clinicians currently have the option of using the 1995 or 1997 CMS documentation guidelines for E/M services, although for mental health providers the 1997 version is the obvious choice. The E/M codes are generic in the sense that they are intended to be used by all physicians, nurse-practitioners, and physician assistants and to be used in primary and specialty care alike. All of the E/M codes are available to you for reporting your services. Psychiatrists frequently ask,“Under what clinical circumstances would you use the office or other outpatient service E/M codes in lieu of the psychiatric evaluation and psychiatric therapy codes?” The decision 30 Procedure Coding Handbook for Psychiatrists, Fourth Edition to use one set of codes over another should be based on which code most accurately describes the services provided to the patient. The E/M codes give you flexibility for reporting your services when the service provided is more medically oriented or when counseling and coordination of care is being provided more than psychotherapy. (See p. 44 for a discussion of counseling and coordination of care) . Appendix K provides national data on the distribution of E/M codes selected by psychiatrists within the Medicare program. Please note that although there are many codes available to use for reporting services, the existence ofthe codes in the CPT manual does not guarantee that insurers will reimburse you for the services designated by those codes. Some insurers mandate that psychiatrists and other mental health providers only bill using the psychiatric codes (90801–90899) . It is always smart to check with the payer when there are alternatives available for coding. THE E/M CODES • E/M codes are used by all physician specialties and all other duly licensed health providers. • The definitions of new patient and established patient are important because of the extensive use of these terms throughout the guidelines in the E/M section. A new patient is defined as one who has not received any professional services from the physician or another physician of the same specialty who belongs to the same group within the past 3 years. An established patient is one who has received professional services from the physician or another physician of the same specialty who belongs to the same group within the past 3 years. When a physician is on call covering for another physician, the decision as to whether the patient is new or established is determined by the relationship of the covering physician to the physician group that has provided care to the patient for whom t
