Does data factor into this ED E/M claim? Given the recent and extensive changes to the evaluation and management (E/M) codes, it’s always helpful to refresh your knowledge and understanding of E/M coding to benefit your practice. That’s why we’ve put together this scenario to see how well you’re grasping the nuances surrounding all the elements that go into determining the level of medical decision making (MDM), including the complex equations that comprise the amount and/or complexity of data to be reviewed and analyzed element. Think you’re up for the challenge? Read on and see if you agree with our assessment. Scenario: A 70-year-old patient with dementia presents after falling off a three-step ladder. After an E/M service and some radiological exams of the foot, the ED physician diagnoses the patient as having a closed fracture of the third metatarsal of the left foot. The physician is able to gather more information related to the injury from the patient’s spouse, who accompanied them to the visit. The physician treats the swelling by applying a plaster-molded splint to immobilize and protect the fracture. Then, they refer the patient to an orthopedic clinic for follow-up treatment in two days.
Calculate the Data Correctly As you consider which codes to choose for this encounter, it’s important to remember the MDM table and how the complexity of data to be reviewed and analyzed element applies to this visit. “In the past, if you ordered one or five radiology tests, you only could claim one point for that. Now that they have added into the data section, they are finally making sure practitioners are getting credit for each unique source of data and testing,” said Betty A. Hovey, BSHAM, CCS-P, CDIP, CPC, COC, CPMA, CPCD, CPB, CPC-I, AAPC Approved instructor during her presentation, “Understanding the MDM Table,” at the La Crosse, Wisconsin, AAPC chapter meeting last August. “The expansion of the data column is good in one way, but has added so much complexity in there, that you must be much more precise in your documentation in order to get credit for everything properly. I always say to the practitioners, ‘If you think it, ink it. Otherwise, you can’t get credit,’” said Hovey. Remember: If the physician is separately reporting a CPT® code that includes interpretation and/or report, this interpretation and/or report should not be counted in the MDM when selecting an office visit code. Capture Independent Historian’s Input Given the patient’s existing dementia diagnosis, the practitioner depended upon the patient’s spouse to provide a comprehensive account of the injury’s circumstances. Because of this, the spouse would be considered an independent historian. Independent historians are relied upon when the patient has a medical condition which renders them unable to communicate effectively, or they are considered unreliable due to a developmental delay or, in this case, a dementia diagnosis. When you do this, “you need to make sure the practitioner documents the reason for using the independent historian,” said Hovey. Note: The independent history does not need to be taken in-person during the visit, but it does need to be obtained directly from the historian providing the independent information. “The practitioner’s notes need to be very clear. For example, ‘Due to patient’s developmental status, history obtained from spouse’ would be an effective note,” said Hovey.
Coding the E/M If you think you can make a case for the E/M MDM level in this situation to be moderate, you are correct. After all, the physician ordered and interpreted the X-rays and relied on the assessment of the independent historian (the patient’s spouse). This would satisfy the Category 1 requirement for the moderate level of data to be analyzed element of MDM. However, this is only one of out of three MDM elements that must be met or exceeded. As the patient has an acute, complicated injury, the number and complexity of problems addressed at the is also moderate. Similarly, the patient’s risk of morbidity from treatment — the splint and follow-ups with an orthopedic specialist — is moderate; thus, the overall MDM is moderate. This makes 99284 (Emergency department visit for the evaluation and management of a patient, which requires a medically appropriate history and/or examination and a moderate level of medical decision making) the most appropriate choice for the E/M level for this scenario.
