Reader Question:
Preventive Services vs. E/M
Published on Thu Jun 01, 2000
Question: I am new to coding and confused about the distinctions between a preventive services code and an evaluation and management code. Also, what is meant by split bill?

Answer: CPT guidelines state that preventive medicine codes 99381-99397 describe encounters with patients who are presenting for reasons that generally do not include diagnosis or treatment of a symptom or illness (although these may be addressed during the course of an encounter as discussed below). Evaluation and management (E/M) codes 99201-99215 are assigned to new or established patients when they are seen for a problem-oriented exam that may include taking a history and making medical decisions about treatment for the patients condition.
Initial and periodic preventive evaluations include a comprehensive history and comprehensive physical exam in addition to counseling and risk-factor reduction advisement. Coders should recognize that the history and exam portions of the preventive service do not directly coincide with the requirements of other E/M services. Different levels of E/M services are distinguished by the complexity of the exam and the time devoted to it. But preventive services are based on exams that are appropriate for the patients age and identified risk factors. For instance, CPT code 99381 is assigned when preventive services are provided to a new infant patient, while 99384 would be assigned to a new adolescent patient. Preventive services do not include immunizations, or laboratory or radiological services.
CPT guidelines indicate that when the physician encounters an abnormality or pre-existing condition that is significant enough to require additional work to perform the key components of a problem-oriented E/M service during a preventive visit, an E/M visit may be reported in addition to the preventive service. The E/M code should be reported with modifier -25 (significant, separately identifiable evaluation and management service by the same physician on the same day of the procedure or other service). Split bill is the term commonly used to describe instances when both a preventive service visit and an E/M code with modifier -25 are reported.
For example, a 45-year-old woman makes an appointment for a preventive visit. During the checkup, the patient complains of lethargy and increased thirst during the past few months. Concerned that she may be developing diabetes, the physician focuses part of his examination on these symptoms and orders appropriate lab work. This encounter would be coded as a split bill: 99396 (established patient, periodic preventive medicine, 40-64 years) would be assigned with the appropriate level of E/M visit for an established patient (e.g., 99212 or 99213). The E/M code would be assigned with the -25 modifier.
Many coding experts believe that practices lose a lot of revenue by not using the split-bill approach. Patients may schedule a [...]
