Cockroaches should take lessons from the billable hour. Detractors notwithstanding, it has survived every economic downturn of the last 30 years including, apparently, this one. Although a recent ALM survey noted that almost 75% of client payments in 2009 were pursuant to “alternative fee arrangements,” almost 80% of those were simply discounts from attorneys’ hourly rates.

Here’s the real problem: Whenever the regime eventually crumbles, the worst aspects of the billable hours culture will persist. Take fixed fee caps, for example. Even if they benefit some clients financially — a big “if” that’s a separate discussion — they create a Hobson’s choice for associates.

On one side is the pressure not to log all time. Keeping matters within internal budgets makes billing partners look good in their year-end reviews.

On the other side stands the billable hour as the definitive metric for measuring individual productivity. They might be working on fixed fee matters, but attorneys must still account for their time. Large firm minimum hours requirements aren’t going away.

What happens when externally fixed fees meet internal billable hours cultures? Ask your doctor.

Do you sometimes get the impression that your family physician is rushing through an appointment? That’s because the doctor is responding rationally to something called the relative value unit (RVU) — medicine’s equivalent to the billable hour.

In 1964, the AMA created reimbursement codes for the newly enacted Medicare program. Fifteen years later, a Harvard School of Public Health economist began investigating ways to compare the seemingly incomparable: the time and effort associated with doctors’ diverse tasks. The typical economist’s study sought to develop relative values for measuring productivity across a range of different activities — from well-child checkups to brain surgery.

The academic exercise remained theoretical until 1985 when Medicare expanded the inquiry: Might such a scale be used to control costs associated with spiraling “reasonable, customary and prevailing fee-for-services” payment schedules? In 1992, Congress linked the relative value unit system to the Medicare codes used for reimbursing more than 7,000 different physician tasks. Private health insurers soon adopted RVUs for reimbursement, too.

Physicians now generate RVUs to earn a living, but time becomes a critical limiting factor. For example, whether a family physician spends 10 or 30 minutes on a routine office visit, Medicare and insurance companies set physician reimbursement at the activity’s predetermined RVU value (0.7). That gets multiplied by the uniform RVU rate (about $40/RVU) for a total of $28. (The final bill exceeds $28 because practice expense and malpractice RVU-factors get added.)

Specialists’ tasks have greater RVU values than general practitioners.’ Compared to a 15-minute routine visit worth 0.7 RVU, a 30-minute colonoscopy is worth several times that. Such differences relate to physician training, skills, mental effort, judgment, stress, and other aspects of the work. But cynics note that specialists have dominated Medicare’s RVU schedule advisory boards.

Behavior has followed incentive structures:

— RVU-driven compensation differences have created shortages of family physicians.

— Specialists mean well, but they tend to view patients myopically through the prism of their expertise, rather than as entire beings. Piecemeal medicine results.

— The system encourages pills, procedures, and tests. Prescription drugs promise quick fixes that move patients out of their doctors’ offices sooner. Procedures generate high RVU values; tests requiring expensive equipment likewise reap generous reimbursement.

Meanwhile, doctors must meet minimum annual RVUs, sometimes pursuant to explicit contractual requirements. That should sound familiar to any big law associate.

As physicians ceded control of hospitals to lay managers, RVUs became a key tool by which the MBA mentality of misguided metrics overtook that profession. Don’t take my word for it. Ask your doctor — if he’ll give you the time.

What would happen if clients and the courts that approve fee petitions started “fee-capping” lawyers the way Medicare and insurance companies have sliced into doctors’ incomes since 1992? Probably unintended consequences no less dramatic than those still surprising the medical profession. Many haven’t been pretty.

Here’s the real kicker: Unlike the legal profession, most physicians have always liked their jobs.
