Medi-Cal Dental $1,800 Annual Cap and Proposition 56 Supplemental Payments Through July 2027
Running a billing department for a dental practice in California right now? You’ve probably felt the ground shift beneath you. Between the $1,800 annual soft cap on adult Medi-Cal Dental benefits and the looming end of Proposition 56 supplemental payments, a lot is riding on getting your billing process right.
Here’s the thing: these aren’t just policy footnotes. They directly affect your cash flow, your accounts receivable, and how quickly your claims actually get paid. Let’s break it all down, plain and simple, so you’re not caught flat-footed.
California’s Medi-Cal Dental program, formerly known as Denti-Cal, caps adult benefits at $1,800 per calendar year. Effective July 1, 2027, practices will not be paid for Prop 56 dental payments. Both of these moving parts require you to review and improve your billing practices.
Here, we’ll discuss what these policies are, how they’re changing, and how to leverage California dental billing services to secure timely claim reimbursements.

What is the $1,800 Annual Cap?
Adults aged 21 or older enrolled in Medi-Cal Dental have an annual benefit ceiling of $1,800. And it’s a soft cap.
The thing is, once a patient’s claims hit that $1,800 mark, treatment doesn’t just get rejected outright. Instead, it triggers a Treatment Authorization Request (TAR), a formal process where the dentist proves medical necessity before moving forward.
The reason this structure exists is that patients with legitimate ongoing dental needs aren’t simply cut off once they reach the threshold.
And here’s where things get complicated. If you schedule a major restorative procedure, such as a crown, denture, or root canal, without checking whether the patient has already utilized their maximum cap, and you skip the TAR, that claim can get denied outright.
And guess what happens next? You don’t get reimbursed, the patient gets a surprise bill they weren’t expecting, and your front office spends hours managing the patient dispute. Not exactly a Tuesday your front-end team wants.

The Proposition 56 Cliff: What's Set to Change After July 1, 2027?
Let’s dive into the new Proposition 56 updates.
So, Prop 56 uses tobacco tax revenue to give dentists supplemental payments, anywhere from 20% to 60% on top of the base Schedule of Maximum Allowances (SMA). It was meant to boost the low Medi-Cal reimbursement rates. However, originally set to end on July 1, 2026, it’s extended to a year later on July 1, 2027. Under California Senate Bill 101, all dates of service on or after that day get paid at the base SMA rate only. There isn’t any supplemental add-on.
What is the Grace Period for Proposition 56?
There’s a one-year runout window (July 1, 2027 through June 30, 2028) for claims tied to dates of service on or before June 30, 2027. But you must submit claims on time. If you wait longer to submit the claims, it’ll affect your reimbursement and reduce the payment per claim.
As per the California Department of Health Care Services, the table below explains the base SMA percentage for Prop 56.
| Claim Submission Timing | Base SMA Paid | Prop 56 Add-On Paid? |
|---|---|---|
| Within 6 months after the end of the month of service | 100% | Yes |
| 7 to 9 months | 75% | Yes |
| 10 to 12 months | 50% | Yes |
| Over 12 months | 0% (Denied) | No |
How Should Your Practice Respond Before the Deadline?
Audit your Q1 and Q2 2027 claims
Pull every case with a date of service between January 1 and June 30, 2027. Cross-check against your AR aging report so you don’t miss any due payments.
Push for fast submission
Keep in mind that waiting past six months means losing money to the tiered SMA reduction. It means that you’ll be paid 75% of the reimbursement rate if you submit claims after six months from the time of service. The best way to do it is to train your billing team or outsource the dental billing and coding services to a company like TransDontics, which doesn’t just submit quick claims but also reviews any pending claims. Their expert billers submit claims on time, so you don’t have to wait for reimbursement and lose any payment.

Update your front-desk verification policy
For any posterior crown, denture, or major procedure scheduled after July 1, 2027, check the patient’s benefit usage upfront. If they’re near the cap, get the TAR process moving before you start the treatment; otherwise, it’s a claim denial and a revenue loss your practice can’t afford to bear.

Conclusion
The $1,800 cap is here to stay, and the Prop 56 supplemental payment has come to an end on July 1, 2027. Practices that get ahead of this by auditing old claims, tightening TAR verification, and submitting promptly come out in much better financial shape than those who wait and see.
Don’t let outdated billing practices affect your revenue. A little proactive planning now saves a whole lot of collection hassles later.
