"That's not true," I replied.
The doctor looked confused. I wasn't disagreeing with his medical opinion; I was disagreeing with reality. Because in modern healthcare, it doesn't really matter what the doctor thinks. It matters what ends up in the chart. And somehow, despite the physician examining the patient, reviewing the labs, and making the diagnosis, the patient will probably leave the hospital with "hypoxemic respiratory failure" listed on the final coding summary anyway. Welcome to healthcare in 2026.
As a respiratory therapist, I was taught that respiratory failure actually meant something. There were criteria, definitions, and evidence. If a patient was hypoxemic, that didn't automatically mean respiratory failure. Failure of oxygenation is failure of oxygenation—it is not failure of ventilation, it is not failure of respiratory drive, and it is not failure simply because someone put the patient on two liters of oxygen. Yet, somewhere along the way, we created a system where nearly every patient who needs a light breeze of oxygen is apparently suffering from a catastrophic failure of their respiratory system.
It’s a bizarre dance. A patient comes into the ER. Pulse oximeter says 88%. The nurse applies two liters via nasal cannula. Pulse oximeter now says 94%. The patient is sitting comfortably in bed, talking about the Detroit Tigers.
Doctor: "Mild hypoxemia." Coder: "Acute hypoxemic respiratory failure." Doctor: "No." Coder: "Yes." Doctor: "The patient is stable." Coder: "Respiratory failure." Doctor: "They're watching baseball." Coder: "Respiratory failure."
At some point, the diagnosis stopped belonging to the people actually caring for the patient.
The absurdity doesn't stop there. The same thing happens with pneumonia. A patient comes in coughing. Do they have pneumonia? Nobody knows. Chest X-ray is normal. No infiltrate. No fever. No positive cultures. No convincing evidence of infection. So what’s the diagnosis? Community-acquired pneumonia. Or my favorite: "walking pneumonia." I’ve often joked that "walking pneumonia" means the patient isn’t sick enough to look like they have pneumonia, but we’re going to call it pneumonia anyway.
Doctor: "The chest X-ray is negative." Me: "So they don't have pneumonia?" Doctor: "Correct." Me: "Then what's causing the cough?" Doctor: "I don't know." Me: "So what do we call it?" Doctor: "Community-acquired pneumonia."
Medicine becomes much easier when we stop worrying about whether the patient actually has the disease. The same thing happens with COPD. A patient who never smoked, has no pulmonary function testing, and no evidence of fixed airway obstruction suddenly has COPD because they wheezed. Asthma? Sure, why not. No testing, no demonstration of reversible airway obstruction, no methacholine challenge—but they wheezed once in 1997. Good enough.
The real problem isn't just the diagnosis itself; it’s what happens afterward. Every diagnosis gets counted. It enters the statistics. It becomes part of the data. Researchers count it, government agencies count it, and hospital quality programs count it. Future providers see it and repeat it.
This isn't just an administrative annoyance; it creates a dangerous medical history. When a patient leaves the hospital with a diagnosis of "respiratory failure" that they never truly had, that label follows them like a digital shadow. The next provider—perhaps an urgent care clinician or a specialist—sees that diagnosis in the electronic health record and assumes it’s fact. It triggers a cascade of unnecessary monitoring, redundant testing, and potential medication adjustments based on a phantom illness. We aren't just inflating statistics; we are polluting the patient’s clinical record with misinformation that can cloud judgment for years to come.
Soon, the data shows more respiratory failure, more pneumonia, more COPD, more asthma, and more diabetes than may have actually existed. Then we wonder why healthcare statistics seem so detached from reality. The diagnosis becomes true simply because somebody typed it into a computer.
The crazy part is that I don’t really blame the doctors, the coders, or even the hospitals. The system rewards it. Government regulations, reimbursement formulas, quality measures, audits, and documentation requirements have created a world where uncertainty is unacceptable. "I don't know" isn't a billable diagnosis. "Mild hypoxemia without respiratory failure" doesn't fit neatly into the boxes. "Shortness of breath of uncertain cause" doesn't fit neatly into the boxes. The system demands a diagnosis, so a diagnosis appears. Everyone follows the rules. Everyone checks the boxes. Everyone documents appropriately. And somehow, the patient ends up with diseases they never actually had.
So, when a physician tells me, "This patient does not have hypoxemic respiratory failure," and the chart later says they do... who am I supposed to believe? The doctor, or the computer?
Because these days, I’m not entirely sure the doctor gets the final vote.
