Neurosurgery Coding Alert

Confirm if you can report established patient codes.

When you report E/M services, you’ll stand a better chance of claims success if you ask yourself the following two questions:

• 1. Is the patient new or established?
• 2. What are the documented levels of history, physical exam, and medical decision-making (MDM)?

Here is how these questions guide you to the best E/M code.

3 Year Rule Determines Patient Status

Generally, you should consider a patient to be established if any physician in your group (or, more precisely, any physician of the same specialty billing under the same group number) has seen that patient for a face-to-face service within the past 36 months, says Marvel Hammer, RN, CPC, CCS-P, PCS, ASC-PM, CHCO, owner of MJH Consulting in Denver, Co.

For example: A patient complaining of recurrent headache and blurring of vision comes to your office. Although this is surgeon A’s first time meeting the patient, surgeon B, in the same group practice, saw the patient two years ago for a similar complaint. In this case, the patient is established. “Since both surgeons presumably share their medical record and cross-cover one another’s patients, a patient seen by any of the partners within the past 3 years is an established patient to all of the partners,” says Gregory Przybylski, MD, director of neurosurgery, New Jersey Neuroscience Institute, JFK Medical Center, Edison.

Don’t Let Different Locations Lead You Astray

If your practice has multiple locations, and a physician in location A sees the patient in January but a physician in location B sees the patient the following December, the patient is still established. The need to create a new chart is inconsequential, Hammer says.

Non-Face-To-Face Encounters Don’t Count

A primary-care physician recommends that a 60-year-old female see the neurosurgeon regarding spondylolisthesis. One of the physicians in your practice interpreted some X-ray results for the same patient the previous year but provided no face-to-face service. “In the absence of the necessary face-to-face encounter to perform a history and examination as well as forming an initial treatment plan, a new patient relationship has not yet been established,” says Przybylski.

In this case, you can still consider the patient to be new when selecting an initial E/M code because no physician within your practice provided the patient with a face-to-face service within the past three years.

According to section 30.6.7 of the Medicare Claims Processing Manual, “An interpretation of a diagnostic test, reading an X-ray or EKG, etc., in the absence of an E/M service or other face-to-face service with the patient does not affect the designation of a new patient.”

Exceptions Could Occur for Different Specialties

The new patient rule applies when physicians in the same practice are also of the same specialty.

In a nutshell: If your practice is big enough and covers enough specialties, two physicians may see a patient for completely different reasons. This could allow you to report a new patient visit even though two physicians in the same practice saw the same patient within a three-year period.

Example: A neurologist in a large multiple-specialty practice sees a patient in 2011 for epilepsy treatments. In early 2013, the same patient sees your neurosurgeon — who is a member of the same multi-specialty practice as the neurologist who earlier treated the patient — for an office E/M service regarding a possible surgical treatment.

Because the neurologist and the neurosurgeon (who are obviously of different specialties) saw the patient for completely unrelated problems, you may report the surgeon’s initial visit with the patient using the new patient codes. “The definition of separate specialty is based on Medicare designation. There are no subspecialty designations in neurosurgery,” says Przybylski.

Consult Codes Don’t Differentiate

The consult codes do not differentiate between new and established patients. Therefore, regardless of the patient’s status, you should make your outpatient consult code choice from the 99241-99245 range. A consultation service requires a request for the consultant to evaluate the patient as well as a requirement to communicate their findings back to the requesting health care professional,” says Przybylski.

When reporting consults and new patient E/M services, you’ll need to meet the requirements of all three key components (history, exam and MDM) to report a given level of service.

Shortcut: In effect, this means that whichever key component is the -lowest- will determine the E/M service level you choose, Hammer says.

Example: During an office visit with a new patient, the surgeon documents a comprehensive history, a comprehensive exam and MDM of low complexity. In this case, the physician has met the history and exam requirements for 99204 (Office or other outpatient visit for the evaluation and management of a new patient ...) but the MDM requirement for 99203. Because the level of the lowest key requirement also determines the E/M service level for new patient office visits, you must choose 99203 in this case.

The AMA added text to CPT® in 2006 to clarify that all of the key components (history, exam and MDM) must meet or exceed the stated requirements to qualify for a particular level of service for office, new patient (99201-99205), hospital observation services (99218-99220), initial hospital care (99221-99223), office consultations (99241-99245), initial inpatient consultations (99251-99255) and others.

Alternative example: During an initial inpatient consultation, the surgeon documents a detailed history, a detailed examination and MDM of moderate complexity. Because you have met or exceeded all three categories for a level-three service of this type, report 99253 (Initial inpatient consultation for a new or established patient ...). “For inpatient consultations, the requesting physician must document the request for consultation in writing in the medical record,” says Przybylski.

2 of 3 Will Do for Most Established E/M Visits

When reporting most established patient outpatient E/M services (except consults and observation care, which do not distinguish new from established patients), you can assign an E/M level based on just two of the key components, Hammer says.

Example: The surgeon sees an established patient with a new complaint. The physician documents a problem-focused history, expanded problem-focused exam, and low-complexity MDM. In this case, the history only meets the level of 99212, but because the other two components meet the requirements for 99213, you may report this higher-level service.

Per CPT®, you must meet or exceed the stated requirements for two of the three key components for established patient office visits (99212-99215), subsequent hospital care (99231-99233), subsequent nursing facility care (99307-99310) and others.

Watch for Overcoding

Generally, medical necessity should determine the MDM level and, ultimately, the appropriate E/M service level. Physicians should not, for instance, report a comprehensive history and exam at every visit and expect to report 99215, regardless of medical necessity or the documented level of MDM.

Simply stated: If the presenting problem won’t support a high-level E/M service, you can’t get paid just because the physician documented a comprehensive history and exam.

A final note: Remember, you may report E/M services based on time — rather than the key components of history, exam and MDM — if the physician spends more than 50 percent of the visit on counseling and/or coordination of care.
