Medical billing and coding is an important part of the healthcare business. It is not enough to just accurately diagnose and treat an illness; you also need to accurately document, code and bill for the services provided. Non-familiarity with the rules and codes leads to under billing for the services provided. While it is possible that you may be underpaid for the services; it is also possible that your claims may be denied.
E & M Codes
E & M stands for ‘evaluation and management‘. E & M codes are the current procedural terminology (CPT) codes that describe patient – physician encounter. E/M codes are numeric and consist of five digits. Selecting the correct E/M code depends on the accuracy of the documentation provided. While precise documentation helps healthcare providers to evaluate and plan the line of treatment, it is also required by healthcare payers to ensure that the service provided is within the ambit of the patient’s insurance coverage. E/M services are documented based on three key components – History, Physical examination and Medical decision making. Unless the healthcare provider is coding based on ‘time’; these three key components are enough to satisfy E/M documentation requirements.
The CMS along with the AMA have developed the E/M guidelines – a set of rules that dictate the documentation required for each E/M code. The first version of the guideline was released in 1995 and the second and last in 1997. Both the versions are nearly identical in context to the history and medical decision making. However, there are substantial differences in the documentation required for the key component of physical examination. Healthcare providers have to select between the two versions of the E/M guidelines in their documentation of an E/M encounter.
Billing for an E/M service requires the selection of the CPT code that best represents the type of patient, the place/setting of the encounter and the level of service performed. Patients are identified as either new (one who has not received any professional service from the healthcare provider within the last three years) or established (one who has received professional service from the healthcare provider within the previous three years).
The place/setting of the physician-patient encounter could be an office or outpatient setting, a hospital inpatient, an emergency department, or a nursing facility. E/M services are defined into different categories and levels. While the three key components of E/M services provided are history, physical examination and medical decision making, an exception to this rule is encounters relating to counseling and/or coordination of care. As a thumb rule, the higher the complexity of the encounter, the higher the level of code used.
