Watch out for CPT/Medicare differences when counting HPI elements. If you're not accurately accounting for the history of present illness (HPI) documented by your cardiologist, you could be missing out on opportunities to report level 4 or 5 E/M visits. Ensure you're not missing higher-pay possibilities by reviewing this guide to capturing HPI elements. Brush Up on What Qualifies as an HPI Element HPI is one of the four parts comprising an outpatient E/M history. It describes the patient's present illness or problem, from the first sign/symptom to the current visit, and typically influences your cardiologist's decisions about the physical examination and treatment. "The information gathered during the physical exam (PE) portion of a patient's evaluation often only shows a very limited picture of the patient's problem. However, speaking with a patient and gathering the history of the patient's problem can relate the entire picture," explains Amanda S. Stoltman, CCS-P, a compliance coder in Muncie, Ind. "Therefore, the HPI oftentimes is the most important aspect of a patient's evaluation." Start counting: CPT only lists seven HPI elements, with duration not making the list. Therefore, for Medicare payers, you should consider duration and timing separately. With payers that follow CPT, however, be aware of this distinction. Start Counting to Differentiate Brief, Extended There are two different types of HPI: brief and extended. If your cardiologist documents one to three HPI elements, then he performed a brief HPI, according to CMS documentation guidelines. When you have a brief HPI you won't be able to code any higher than a level two new patient E/M (99202, Office or other outpatient visit for the evaluation and management of a new patient ...), regardless of the encounter's other specifics. For an established patient, a brief HPI can support up to and including 99213 (Office or other outpatient visit for the evaluation and management of an established patient ...). Alternative: Example: Caution: "Make sure your doctors obtain and document as much information as possible to allow billing a higher level E/M," says Ruth Borrero, claims analyst at Prohealth Care in Lake Success, N.Y. But remember that medical necessity dictates the level of service the cardiologist should provide. Auditors may view performing and reporting a higher-level service than is necessary as fraudulent. Ensure that the Provider Documents the HPI Remember that the physician must be the one who obtains the HPI, according to CMS guidelines. He cannot use or report information obtained by his staff only. Your cardiologist must personally obtain, refine, add to, complete, and document the HPI if he expects to receive credit and reimbursement for his services. The HPI rule contrasts with CMS's rule for other history components. Any employee in your practice, or even the patient himself, can document part of the history, Borrero says. In fact, the E/M service documentation guidelines state that ancillary staff may obtain and record the review of systems (ROS) and/or past family social history (PFSH). The physician must review both the ROS and PFSH, sign both as an indication of his review, and indicate any additions he personally documented, however. Important:
