What is contingency (percentage-of-collections) RCM for behavioral health, and what does it cost?

What is contingency (percentage-of-collections) RCM?

Contingency RCM is a pricing model where you pay your billing or recovery partner a percentage of what they actually collect, rather than a fixed fee. It is also called percentage-of-collections. The two common alternatives are a flat monthly retainer and a per-claim fee — and the difference is what you are paying for: activity, or results.

Under a per-claim model, you pay a set amount every time a claim is submitted — commonly $3 to $10 per claim — whether or not it gets paid. Under a flat retainer, you pay the same number each month regardless of what comes in. Contingency ties the cost to the collected dollar instead, so the partner only earns when you do.

That incentive is the whole point, and it matters most for the work nobody is paid to do under the other models: the continued-stay appeals, the underpaid claims, the aged accounts. A per-claim biller is paid to submit, not to fight a denial; a contingency partner is paid only if the denial is overturned and the money lands. For a behavioral health facility, that is exactly where the recovery of denied claims actually happens.

What does contingency billing actually cost for a behavioral health facility?

For full-service percentage-of-collections billing, expect roughly 4% to 10% of collections, with most practices in the 5% to 7% band. Where you land inside that range is driven by volume and complexity — not by the vendor’s mood — so it is reasonably predictable once you know your own numbers.

Two independent reads put the range in the same place. A 2022 survey of medical billing companies by the practice-software firm Tebra found a typical range of 4% to 10%, with about a quarter of the billing companies surveyed (24.5%) charging 6% to 7%. A buyer-side breakdown from the physician-run resource Physician Side Gigs reports the same 4% to 10% span, with most private practices saying their companies charge 5% to 7%. High-volume practices sit toward the lower end; smaller practices, or those bundling extra services like coding, sit toward the upper end; and rates under 4% usually signal a stripped-down or automated service with little incentive to chase the hard collections.

Behavioral health tends toward the work-intensive half of that range, for the same reason its claims get denied more often. Partial hospitalization (PHP), intensive outpatient (IOP), residential, and detox are billed largely per diem, with continued-stay reviews, ASAM medical-necessity criteria, and carve-out payers all adding labor per dollar collected. The headline percentage, though, is only half the question — what the percentage is charged on matters just as much.

A percentage of what — gross collections, net, or only recovered money?

This is the number that actually decides your cost, and it is the one buyers skip. A percentage of gross collections, of net collections, or of only the money recovered are three very different deals at the same headline rate. Read the base before you compare two quotes.

Gross vs. net: a percentage of gross collections is taken off every dollar that comes in the door; a percentage of net collections is taken after refunds, adjustments, and write-offs. Full-service vs. recovery: a full-service contingency takes a cut of everything collected, ongoing — including money you would have collected anyway. A recovery contingency is paid only on recovered dollars: claims that were denied, underpaid, or aging toward write-off and then actually got paid.

That distinction changes the risk math. Because a recovery contingency is paid out of money that was otherwise heading to zero, the downside is structurally capped — as long as the fee is charged only on genuinely recovered dollars, with no monthly floor or setup fee, the worst case is that you stay roughly where you are. The trade-off is honesty about the rate: recovery work is priced less uniformly than full-service billing, because it varies by how stuck the claims are and which payers are involved. So when the base is “recovered” money, judge the deal on how recovered is defined and what counts toward it, not on the headline percentage alone.

How is contingency different from in-house staff or a per-claim biller?

It is a variable cost instead of a fixed one. In-house billers and per-claim services cost you the same whether or not the money comes in; a contingency costs you nothing until it does. For recovery work specifically, that difference is the entire argument.

An in-house biller is salary plus benefits regardless of collections, and the denials compete with daily claim submission — so the appeals get triaged last and age out. A per-claim or flat-fee vendor is paid for the activity of submitting, not the outcome of collecting, so there is no built-in reward for working a hard continued-stay appeal. The economics show up in how much is simply abandoned: industry analyses citing AHIMA Journal data estimate that 35% to 60% of denied or returned claims are never resubmitted, and reworking a single denied claim costs roughly $25 to $181.

So the real comparison for recovery is not “a contingency percentage vs. a salary.” It is “a share of recovered dollars vs. zero,” because the honest alternative for most denied behavioral health claims is a write-off. You are paying a cut of money that was not otherwise coming in.

What should you check before signing a contingency RCM contract?

The headline percentage is the least important line in the contract. Check the base it is charged on, what is bundled in, whether there are floor charges, and how “recovered” is defined — those decide what you actually pay.

The base: gross collections, net collections, or recovered-only — a 7% on gross is more than 7% on net. Floor charges: true contingency has no setup fee, no monthly minimum, and no per-claim add-on; a monthly floor means it is not pure contingency. What is included: coding, eligibility and benefits verification, utilization review and continued-stay appeals, denial appeals — or just claim submission. Behavioral health revenue leaks in UR and appeals, so a “billing” contingency that quietly excludes appeals leaves the expensive work undone.

New money vs. baseline: for recovery work, confirm in writing that you are paying a share of claims that were genuinely stuck — not a percentage of money you would have collected anyway. Government payers: percentage-based compensation tied to Medicare or Medicaid claims carries its own compliance considerations, so ask how the vendor handles those rather than assume the commercial arrangement carries over. Rip-and-replace: confirm the partner layers on top of your current biller and EHR instead of forcing a switch — see the homepage questions on contingency and switching systems.

Is contingency a good deal — or do you overpay when collections are high?

Honestly, it cuts both ways. On steady, clean, high-volume billing, a percentage of every collected dollar can cost more over time than an in-house team at scale. On denied, aged, and underpaid claims, a recovery contingency is close to pure upside — because the realistic alternative is a write-off, not a cheaper collection.

What you are buying with a contingency is risk transfer and aligned incentives, paid for as a slice of results rather than a fixed bill. At high clean-claim volume, that slice can add up, and some large facilities do bring routine billing in-house for exactly that reason. But “overpaying” does not really apply to recovery work: a share of money that was not coming in otherwise is measured against zero, not against a cheaper way to collect it.

For many behavioral health facilities the sensible split is both — keep what is already working, and put a recovery contingency on the leaks: the denials, the continued-stay reviews, and the aged AR. You transfer the risk exactly where the money is most likely to be lost, and you pay only if it is found.

Key takeaways

• Contingency (percentage-of-collections) RCM means paying a share of what is actually collected — not a flat retainer and not a per-claim fee.
• Full-service behavioral health billing typically runs about 4% to 10% of collections, most commonly 5% to 7%; volume and complexity move you within the band.
• The base matters as much as the rate: a percentage of gross collections, net collections, or recovered-only money are different deals at the same headline number.
• A recovery contingency is paid on otherwise-lost dollars, so the downside is capped — worst case, you stay roughly where you are.
• The economics favor contingency for recovery work: 35% to 60% of denied claims are never resubmitted, so the real alternative is usually a write-off, not a cheaper collection.
• Before signing, check the base, any floor charges, what is bundled (especially UR and appeals), how “recovered” is defined, and whether it forces an EHR or biller switch.
