Ob-Gyn Coding Alert

Check your coding against these answers to see where you should focus your E/M education.

Answer 1: Yes. Based on E/M guidelines, if a patient's past medical, family and social history (PMFSH) has not changed since a prior visit your ob-gyn doesn't have to document the information again. He does, however, need to document that he reviewed the previous information to be sure it's up to date and also note in the present encounter's documentation the date and location of the initial earlier acquisition of the PMFSH. Some payers will give no PMFSH credit if you overlook one of these criteria.

Both the 1995 and 1997 E/M documentation guidelines include the following: "A ROS and/or a PFSH obtained during an earlier encounter does not need to be re-recorded if there is evidence that the physician reviewed and updated the previous information. This may occur when a physician updates his or her own record or in an institutional setting or group practice where many physicians use a common record. The review and update may be documented by:

• describing any new ROS and/or PFSH information or noting there has been no change in the information; and
• noting the date and location of the earlier ROS and/or PFSH."

Answer 2: The answer depends on your practice, your ob-gyn, the documentation, and the encounter specifics. You can choose whichever set of guidelines is most advantageous for each encounter, explains Suzan Berman , CPC, CEMC, CEDC, Senior Director of Physician Services at Healthcare Revenue Assurance Associates based out of Plantation, Florida.

The key, however, is that you have to use either 1995 or 1997 guidelines for a single encounter. "I have found in my audits that typically, the 1997 documentation guidelines are the most advantageous for ob-gyn practices," says Barbara Cobuzzi, MBA, CPC, CENTC, CPCH, CPC-P, CPC-I, CHCC, president of CRN Healthcare Solutions, a consulting firm in Tinton Falls, N.J. "This is because most ob-gyns concentrate on the individual elements of the GU system (up to 11 elements), and in the 1995 guidelines, GU is counted only as one organ system."

Answer 3: Medical necessity should always be the overarching factor used to select the E/M service level. Just because a physician completes a comprehensive history and examination doesn't always mean he should report a level-five code. Medical necessity should always drive the components that he performs. Practices that try to exploit this loophole could be severely miscoding E/M levels.

This mindset is particularly worrisome with the implementation of EHR systems, which often automatically code encounters without regard to medical necessity. It is very easy to document high levels of history and exams, particularly for established patients, which will result in level four and five services when the medical necessity may dictate only level two or three services.

Caution: Remember that medical decision making is not the same as medical necessity. "The patient may be told to go home with no further treatment, but that doesn't negate all the decision-making that went into that determination," Berman warns. "Thus, the two are not the same. MDM, per CPT® rules, does not have to be one of the two elements in determining the level of established patient." Note, however, that individual payer policies may demand MDM as one of the two components needed to code a level of service requiring only two of the three key components of an E/M service.
