Evaluation and management coding, known as E/M coding, is a critical component of your medical practice since evaluation and management are likely part of any interaction you have with patients. As such, coding practices for E/M services need to be specific and can lead to suspicion or audits if your medical practice has a history of inaccurate E/M coding on claim submissions.
With the level of importance attached to E/M codes, it’s helpful to know that CMS regulations regarding E/M coding recently changed, too. Keep reading to learn what E/M codes are, and get some billing tips for your medical practice to follow.
Evaluation and management coding involves CPT codes that specifically represent services provided by a physician or other qualified healthcare professional; these codes range from 99209 to 99499. E/M services might include office visits, home services, and preventative visits; other types of healthcare services, like surgeries, are not included in this range of CPT codes for E/M services.
When billing Medicare for E/M services, you must select the CPT code that best represents the following:
When determining what level of service was provided, consider the level of history, examination, and medical decision-making that was involved. An important exception to this guidance is if the visit was primarily counseling or coordination of care—in this case, select the code that correlates to the length of time spent with the patient.
Since evaluation and management services are so frequent for your medical practice, small mistakes in the coding of these services can lead to compliance or payment issues if there’s a pattern of inaccuracies. For example, if you overestimate or over-report the amount of time spent with patients that exceeds what a reasonable day would be—say, spending 1 hour with 20 different patients in one day—that could raise a red flag and lead to audits or further questioning by your payers.
Accurate E/M coding is important too for the sake of maintaining accurate and comprehensive medical record documents; E/M services are vital to the patient-provider interaction and for establishing a patient’s healthcare journey, so accurate coding and reporting on these measures help you and your patient.
Since evaluation and management coding is so crucial to your medical practice and the patients you care for, it’s helpful to know a few essentials:
In November of 2018, the Centers for Medicare & Medicaid Services (CMS) issued a final rule that included updates to a variety of regulations taking effect on or after January 1, 2019. The purpose of this ruling was to streamline administrative workflows and reduce unnecessary burdens.
You can read more about the specifics listed in Medicare’s press release regarding the final rule here, but here are a few key highlights—some of which took effect as recently as last year in 2021:
Essentially, these new regulations allow for more flexibility in terms of medical documentation and optimizing workflows to not have unnecessary repetitiveness. Be sure to review your medical practice’s operations to confirm that you’ve implemented these requirements and that you’re staying compliant.
Clarifying if the patient you provided E/M services to is a new or established patient is an important part of accurate E/M coding! Let’s briefly break down what each one means to your practice:
For example, if a patient returns to see a cardiologist within a major medical group and happens to get recommended to see a dermatologist regarding a lesion on their skin, the patient is a new patient for the dermatologist because it’s a different specialty than the original established purpose of cardiology.
What are the most common E/M codes you'll see? If you’re billing for time-based E/M services, keep these codes handy:
When billing based on the complexity of the evaluation and management services provided, consider these codes:
