Barriers to code use persist for PCPs
“What surprised us was that there were many codes; we analyzed 34 in the paper in 13 distinct categories of services, and Medicare continues to add new primary care codes to the fee schedule,” Dr. Agarwal said in an interview. Also surprising, “take-up is low virtually across the board, and this isn’t for lack of eligibility,” he said. The low use of the codes “is not for lack of counseling patients on diet, drinking, exercise, smoking, or anything else for which these codes are meant to pay PCPs ... The potential revenue from these codes in aggregate is huge,” Dr. Agarwal emphasized.
“My hope is not necessarily that physicians read this study and start using some or all of these codes more frequently,” said Dr. Agarwal. “It can be tempting to think of this as money left on the table, but it’s not; there are compliance, billing, and opportunity costs from using these codes,” he said. “For individual PCPs seeing individual patients for the breadth that is primary care, I’m not sure the juice is worth the squeeze,” he added. “My coauthors and I are all primary care physicians. We know from our research and first-hand that these codes can be cumbersome to use.” These codes also don’t reflect how PCPs practice, he said. “PCPs are not in the business of slicing and dicing a visit or patient to extract as much revenue as possible. The physician-patient interaction is more complex, and richer, than these codes imply. Instead, I hope our paper encourages Medicare and policymakers to take a harder look at other strategies for investing in primary care,” Dr. Agarwal added.
As for additional research, “Primary care spending is going in the wrong direction,” said Dr. Agarwal. “We need to figure out how best to finance primary care in the United States.”
Recent studies have examined the successes and limitations of the primary care medical home model, Medicare’s Comprehensive Primary Care Initiative, and primary care spending legislation, he said. “Our study is another piece of the puzzle: at least in its current form,” and the results suggest “that one-off codes were nice in theory but not in practice,” he noted.
New codes are cumbersome
“It’s tempting to interpret underuse of new billing codes as a simple change management problem,” Davoren Chick, MD, chief learning officer of the American College of Physicians, wrote in an accompanying editorial. However, the underuse of codes for preventive service and coordination of care likely stems from the details of the codes, he said.
The new codes require the documentation of specific components and a minimum duration of services, he explained. “Codes that reward discrete service episodes disadvantage physicians who appropriately integrate preventive services within a continuous patient care relationship,” he added.
Dr. Chick presented an example of a primary care physician who would have to deliver intensive behavioral therapy for obesity in 15-minute episodes outside of a routine office visit to meet the billing criteria for current Medicare codes.
Dr. Chick called on clinicians to educate themselves on the coding rules for the services they provide “not only to optimize current payment but also to advocate for change.”
He concluded: “Widespread underuse of new preventive service and coordination of care codes reflects system failure, not physician failure. We must stand firm with this knowledge to demand increased payment for feasible, patient-centered primary care commensurate with its value in achieving better outcomes and lower costs.”
The study was supported by the National Institute on Aging of the National Institutes of Health. Dr. Agarwal and Dr. Chick had no financial conflicts to disclose.
