Don't let varying interpretations of the evaluation and management guidelines keep you from getting paid.
Fam Pract Manag. 2010 Jul-Aug;17(4):27-32.
Enterprises, changed its documentation requirements to prohibit the use of “all others negative” when documenting a full review of systems, and it adopted a new method for determining the level of medical decision making. Today TrailBlazer is not alone in developing its own “interpretations” of the guidelines. After days of Internet searching for guidance on E/M documentation, I discovered widespread differences among MAC policies. Some provide clear, consistent information to physicians based on historical understandings of the documentation guidelines, while others have added restrictions and provide inconsistent and sometimes unclear interpretations. Others offer little to no direction at all.
To be fair, portions of the documentation guidelines are so vague that using them practically requires some interpretation. The most notable example is in the medical decision making section, where the guidelines include a table helpful for assessing risk and relating it to the four levels of decision making but offer no similar tool for assessing diagnosis and management options and data, the other two elements of medical decision making. (See "Thinking on Paper" to brush up on documenting decision making.) To help fill this gap, many contractors use score sheets that assign points for documentation of various diagnoses and management options and types of data review and relate these to the overall level of medical decision making. Responding to a similar lack of clarity in the exam section of the 1995 version of Medicare's documentation guidelines, Highmark Medicare Services developed what it calls a “4x4 tool” to help determine if an exam should be scored as expanded problem focused or detailed. Other ambiguities in the guidelines have spawned frequently asked questions from physicians and others.
The table "Evaluation and management services Q&A: How does your MAC interpret the guidelines?" gives several examples of the welter of interpretations that have grown out of all of this uncertainty. It compares Medicare's documentation guidelines with Medicare contractors' guidelines where the latter were available. In addition, several important questions that the documentation guidelines don't address are listed below.
MORE QUESTIONS TO ASK YOUR PAYERS
Medicare's Documentation Guidelines for Evaluation and Management Services doesn't address the following issues, but your Medicare contractor's answers to these questions may significantly influence how your practice would fair in an audit. Why not ask them now?
Is it necessary to use either the 1995 or 1997 guidelines in their entirety, or is it acceptable to use portions of each, e.g., the 1995 guidelines for exam and medical decision making with the 1997 guidelines for history?
Do you use score sheets to quantify diagnosis and management options and data review related to medical decision making documentation? If so, can these be shared with physicians?
What constitutes an “interval history,” as required for documenting subsequent hospital care?
CMS developed the Comprehensive Error Rate Testing program to determine how accurately MACs pay claims, and CMS says the results consistently demonstrate the need for increased documentation review and provider education for certain E/M services. So before CMS requests your records and your practice receives a hard lesson in documentation and coding, learn the rules the MAC for your state is playing by (see “Who's the MAC in my state?”). Contact the Provider Outreach and Education Department of your MAC, and let the issues raised in this article guide your questions. The following are just a few examples of interpretations that could affect your practice.
WHO'S THE MAC IN MY STATE?
Turnover is high among Medicare administrative contractors, and this can confound practices' efforts to stay in compliance with any unique rules the contractors may have. To keep up with the changes in contractors and jurisdictions, visit the contractors' web sites (listed below) or the CMS Medicare Contracting Reform web page.

History of the present illness
In its Evaluation and Management Services Guide, CMS has stated that documenting the status of at least three chronic or inactive conditions is acceptable support for an extended history of the present illness (HPI) under both the 1995 and 1997 versions of its Documentation Guidelines for Evaluation and Management Services.1 However, the 1995 version of the guidelines available on the CMS web site includes a narrower definition – four or more elements of the HPI (location, quality, severity, duration, timing, context, modifying factors, and associated signs and symptoms). Confused? It appears the MACs are too.
The E/M documentation worksheet for First Coast Service Options reflects the differing definitions, with the status of at least three chronic or inactive conditions constituting an extended HPI only when the 1997 guidelines are used. Palmetto GBA doesn't recognize the status of three chronic conditions under the 1995 guidelines either. But Wisconsin Physicians Service and National Heritage Insurance Corporation (NHIC) accept the broader HPI definition for both versions of the guidelines.
You may wonder if this really matters. After all, HPI is only one of the three documentation elements of a patient history. As Kent Moore wrote in an article about history documentation in the March/April 2010 issue of FPM, the 1995 definition “tends to undervalue the HPI for follow-up visits with patients who have multiple chronic problems. If the problems are well-controlled – enough for the patient to be asymptomatic – even the most careful and thorough HPI might not be able to turn up four or more of the specified elements. (How do you give the duration of a symptom that isn't there?) As a result, this definition of the HPI tends to put a ceiling on the level of the visit: A brief HPI limits the level of history to problem focused or expanded problem focused, and that limits the level of a follow-up visit to 99213 unless both the exam and the medical decision making are involved enough to justify a higher level without reference to the history.”2
To further confuse HPI documentation, Pinnacle Business Solutions, NHIC and Highmark Medicare Services accept the status of one to two chronic or inactive conditions to meet the requirement for a brief HPI. This seems like a logical extension of the extended HPI definition, but Medicare's documentation guidelines don't address it. First Coast Service Options states that a brief HPI requires one to three elements of the HPI, not one to two chronic or inactive conditions. Note, however, that First Coast Service Options' guidance doesn't actually prevent the status of one to two chronic conditions from counting as a brief HPI. For example, if you state that the patient has hypertension that is well controlled with current medications, you have documented a brief HPI in compliance with either definition – noting the status of one chronic condition or two elements of the HPI (quality and one modifying factor).
EVALUATION AND MANAGEMENT SERVICES Q&A: HOW DOES YOUR MAC INTERPRET THE GUIDELINES?
The following questions and answers were found on Medicare administrative contractors' (MACs) web sites. Table cells were left blank if the answer could not be found. Certain contractors are not included in the table because of a lack of information on their web sites. See "Who's the MAC in my state?" to identify the MAC for your state. (Note: This online table includes material that was not included in the print version of the article.)
Medical decision making
Although Medicare's guidelines place no greater emphasis on medical decision making than on history or exam in determining a level of service, some auditors and payers argue that for established patient services that require only two of three key components, medical decision making must be one of the two components.
The results of my research on this issue were confusing. For example, Pinnacle indicates on its web site that any two of the three key components can be used to determine the code selection, but then elsewhere says, “Medical review places the most significant emphasis on the level of MDM [medical decision making] documented and required by the condition of the patient. For example, if 99223 is billed with a comprehensive history, comprehensive examination and moderate level of MDM, this would be recoded to 99222 to reflect the level of decision making ….”
NHIC also gives contradictory information, explaining that medical decision making does not have to be one of the components used for code selection and elsewhere requiring it. NHIC goes as far as to say that if the level of medical decision making is lower than what is required for that code, the service may be downcoded – even if the history or exam component meets or exceeds the level required.
These examples illustrate why it is important to monitor the information provided by your payers, and especially your MAC. Periodically comparing your supporting documentation to payers' requirements and making adjustments as needed will help keep your claims from being denied. Don't let the MAC or its review contractors find an “educational opportunity” in your practice.
