Ob-Gyn Coding Alert

Medicare overspends millions on upcoded inpatient visits Carriers are scrutinizing your inpatient hospital visits more than ever before. Will you be ready?

Problems: Medicare overspent $112 million on claims for subsequent hospital care code 99233 and $41 million on 99232, according to the November 2006 Comprehensive Error Rate Testing report. In both cases, visits were upcoded by one level, CMS says.

Also, Medicare overspent $57 million on upcoded claims for inpatient consult code 99254. And CMS says upcoded claims for initial inpatient care code 99222 cost the program $26 million.

Meanwhile, more than one doctor often tries to bill for initial hospital care (99221-99223) for the same patient, says a bulletin from Healthnow New York's Upstate Medicare Division (UMD). -Only the admitting physician may file a claim for the initial hospital visit,- says UMD, which warns that this is a -common source of error.-

High error rates with inpatient visits are leading to more scrutiny, says Linda Martien, CPC, CPC-H, coding consultant with National Healthcare Review in Woodland Hills, Calif. She and other experts offer these six tips: 1. Don't Confuse -Admission Orders, Initial Visit- Many coders think they can bill for an initial inpatient visit just because the doctor performed a history and physical exam in the office before admission. Because he dictated the history and physical for the patient without a face-to-face visit in the hospital, the doctor may think the practice can bill an initial inpatient visit, but this is wrong, says Maxine Lewis, BA, CMM, CPC, CCS-P, with Medical Coding Reimbursement Management in Cincinnati.

For example: Your ob-gyn sees a patient in the office for a pelvic inflammatory disease (PID) infection. Then the ob-gyn admits her to the hospital for pregnancy complications. This is not part of the global ob, and you can bill for it separately. But you should only report the admission -- not the initial office visit beforehand. But if the hospital treatment includes surgery, then you cannot report the admission.  2. Check the Documentation Look for the physician progress note or bedside note that shows the physician actually spent time with the patient in the hospital and reconfirmed the key components of the E/M visit performed earlier that day in the office, Martien says. 3. Watch Diagnosis Coding Problems arise when one patient is in the hospital with multiple problems, Martien says. For example, a patient could be in a car accident and need an orthopedist, neurologist, ob-gyn and others. Make sure your physician uses diagnosis codes that directly relate to his specialty area, and use modifiers where appropriate, Martien adds. 4. Distinguish Observation and Inpatient Admission Pay attention to the documentation. You may need to follow up with the doctor and even the hospital to [...]
