Negative Space

The Healthcode System  ...  Chapter 6

Every system built on codes obeys one quiet law, and it is the law on which this entire argument turns. What gets coded gets done. What cannot be coded slips, gradually and without anyone deciding it should, out of existence  ...  not because the system rules against it, but because the system has no way to see it, pay it, or count it. A code is a kind of attention. Whatever falls outside the codes falls outside the system's attention, and in medicine, attention is the difference between a thing that happens and a thing that does not.

The law operates first inside the codeable, where the apparatus plays favorites, and its favorites are procedures. Recall the committee from the third chapter, weighted toward the specialists who perform the interventions, and the seed planted there: a body of proceduralists tends to price procedures generously and to price the quieter work thin. To this day that committee reserves only about a fifth of its seats for primary care, though those physicians handle better than a third of the nation's visits.[1] The tilt it built into the fee schedule three decades ago has compounded ever since, until what began as a tendency became a chasm. In 2022 a primary-care office visit drew an average of two hundred fifty-nine dollars, while a single gastroenterology procedure drew one thousand ninety-two  ...  the conversation worth roughly a fifth of the scope.[2] The physicians who perform the procedures out-earn the physicians who do the thinking by well over a hundred thousand dollars a year.[3] Primary care, the place where most prevention actually lives, receives less than five cents of every health dollar, a share that has been falling, not rising.[4] The market reads these prices and responds with perfect rationality. Students choose the lucrative specialties; practices invest in the equipment, not the hour of counsel. What gets coded richly gets done abundantly. What gets coded thinly gets done rarely. The fee schedule is not describing medicine's values. It is dictating them.

A rebalanced fee schedule could narrow that chasm, and the chapters ahead argue it should. Beneath it, though, lies a problem no adjustment of prices can reach, because it is not a problem of price. It is a problem of grammar. A code names an event. Prevention's masterpiece is a non-event. Consider the difference the ledger sees. A coronary stent is a richly coded procedure, a clean and billable event with a date and a price. The years of steady blood-pressure control that meant the stent was never needed are scattered across a hundred unremarkable visits and resolve, on the ledger, into almost nothing. A cancer removed at stage three is a long cascade of well-paid events. The same cancer caught early at a screening and never permitted to become a crisis is one cheap line item followed by silence, and the system reads silence as the absence of value, because silence is precisely what it cannot bill. You cannot code an absence. The disaster has a price. The disaster averted leaves no trace the apparatus knows how to read.

Painters have a name for this. Negative space is the shape of everything surrounding the subject  ...  the void that gives the figure its edges. A skilled hand can draw a vase by drawing only the space around it, letting the absence describe the form. Medicine's billing apparatus can do the opposite and nothing more: it renders the figure and never the ground. It captures every line of the disease  ...  each procedure, each crisis, each coded intervention  ...  and none of the quiet that good health actually consists of. A system that pays only for the figure will, over the decades, produce exactly what it pays for: a medicine crowded with events and starved of the calm that prevents them. We built an apparatus that can see sickness in exquisite detail and cannot see health at all, because health, rendered honestly, is mostly negative space.

Two different invisibilities hide in that negative space, and the rest of this series turns on telling them apart, because they call for two different cures.

The first is the undervaluing of clinical prevention  ...  the screening, the counsel, the patient management of a chronic disease that the code can see but consistently underpays. That invisibility a better payment model can largely correct, by rewarding the outcome rather than the event, the health of the patient rather than the volume of the procedures. Whether such models actually work, and what an honest one would demand, is the subject of the next two chapters.

The second invisibility runs deeper and lies outside medicine altogether. The stable housing, the reliable food, the years of schooling, the breathable air, the paycheck that does not vanish: these shape a human being's health long before any clinician enters the story, and they answer to no code, arrive on no claim, and fit inside no fee schedule, however enlightened. No reform of medical payment reaches them, because they were never medicine's to bill. Reaching them requires something the health-code system was not built to contain and cannot be retrofitted to hold. Naming that thing, and what it would take to build it, is the work of the final chapters.

The first chapter offered a rule: the code is the condition of the care. This chapter supplies the corollary that turns it from observation into indictment. If the code is the condition of the care, then care the code cannot name is care that, under this system, will not happen  ...  and the most valuable medicine we possess, the prevention of suffering before it begins, is precisely the medicine the code was never able to name. We did not sit down and choose to neglect prevention. We built a machine that cannot see it... and then mistook everything the machine could see for the whole of health.
