One Number Decides Your Paycheck, and Most Doctors Can't Name It

The conversion factor sets your income more than the salary on the first page does. Most physicians can't name theirs.

I built and explained comp models like this one for years, so let me translate the part nobody translates for you. Somewhere in your offer sits a number that will do more to set your income than the salary on the first page, and most physicians can't tell you what theirs is.

It's the conversion factor, the dollars you get paid per wRVU, and if that sentence just went a little abstract on you, that's exactly the problem this piece exists to fix. The productivity model is going to read you the moment you start, so you may as well learn to read it first.

Why it matters: The salary is negotiated once and then it's fixed. The conversion factor and the threshold decide what you earn every year after the guarantee ends, which for most physicians is year three onward. One of those numbers you'll live with far longer, and it's the one nobody reads.

What is a conversion factor in a physician contract?

Your employer multiplies your wRVUs by some dollar amount to turn work into pay, and that dollar amount is the whole game. Two offers can quote the same salary and pay completely differently once the guarantee runs out, because one has a generous conversion factor and one doesn't.

So the question that actually matters isn't "what's the salary," it's "what's the conversion factor, and how does it change as I produce more."

What is a work RVU?

Start with the RVU itself. A Relative Value Unit is Medicare's way of scoring how much work a given service takes, so a fifteen-minute follow-up and a complex procedure aren't valued the same.

The one that matters for your pay is the work RVU, the wRVU, which strips out the practice's overhead and malpractice cost and tries to measure just your labor. Every code you bill carries a wRVU value, and if you add them up over a year, you get your production, which is the raw count of what you did.

What is a wRVU threshold, and how do I know if mine is realistic?

Most of these deals give you a guaranteed base for a year or two, and then quietly flip you to production, where you only earn above a certain wRVU threshold. The base feels like a floor, but the threshold is the real floor, and it's often set at a level that assumes you'll be busy.

If your guaranteed base implies a production number you can't hit as a new attending with no referral base, then year three, when the guarantee ends, is going to be an unpleasant surprise. Ask what wRVU target the base corresponds to, and ask honestly whether a first-year version of you can reach it.

Does payer mix affect my pay if I'm on collections?

And if you're paid on collections instead of RVUs, the same skepticism applies to a different variable, which is payer mix.

The same work pays very differently depending on who's insuring the patients, so a collections model in a strong payer market and one in a weak payer market are not the same job, even at the same headline rate. Who owns the practice changes that math too, because what gets deducted before you see a dollar depends on the structure above you.

Is paid time off real under a production model?

Not entirely. Take the week, and on a wRVU or collections model the threshold at the end of the month hasn't moved, so the time away comes out of your own paycheck rather than the employer's.

Why this is worth an afternoon

I'm not walking you through this because the math is interesting. I'm walking you through it because the people who built the model understand every piece of it, and if you don't, you're negotiating a number whose mechanics only one side of the table can see.

That's a strange spot for the most quantitatively gifted people in any building to be in, and yet it happens constantly, because nobody taught this in training and the whole subject looks more boring than it is.

What to get in writing

So do the unglamorous thing. Get:

• The conversion factor, in dollars per wRVU
• The wRVU threshold you have to clear before production pay starts
• What wRVU target your guaranteed base actually corresponds to
• The year-one ramp assumptions, written down rather than described

Then run the arithmetic yourself at a realistic volume rather than the rosy one on the pro-forma.

You already do harder math than this before breakfast, so point that skill at your own paycheck for one afternoon, and the productivity model stops being something that happens to you and starts being something you can negotiate.
