Your practice is leaking money it already earned. Here is where.
I read denied medical and dental claims for a living. I have looked at thousands of EOBs from practices that hired billing companies and watched most of them leave real money on the floor, in the coding and in the credentialing nobody audits. This is the operator view: the leak named, the mechanism shown, the recovery angle that works.
The cornerstones
The leaks a practice never sees.
- A Patient's Linked Dental Claim Just Got Denied. What Do You Actually Hand Them? When a Medicare-linked dental claim is denied and the patient asks what to do next, the practice's job is a referral, not an appeal script. CheckMyDenial's guide walks a patient through reading the denial and understanding their appeal rights in plain language, built for the patient side of this exact scenario.
- An Audit That Only Finds Under-Billed Money Is Not a Compliance Program. It Is a Liability Sitting Next to a Recovery Check. The overpayment statute, 42 U.S.C. 1320a-7k(d), requires reporting and returning any overpayment within 60 days of identification, with False Claims Act exposure for missing that deadline. A billing review built only to find missed revenue, and never structured to surface over-coded claims in the same pass, creates the exposure it should be closing.
- If You Opted Out of Medicare, What Can Your Medicare Patients Actually Do? The Private Contract Rules, Read Straight. A dentist who opts out of Medicare signs a two-year affidavit under 42 CFR 405.405-405.420 and can only see Medicare beneficiaries through a private contract meeting 405.415. Once that contract is in place, no Medicare payment is made for the service, directly or indirectly, even if the patient files the claim themselves.
- Your Patients' Medicare Numbers Are in the Chart, Not in the Insurance Module In one de-identified practice audit, current Medicare Beneficiary Identifiers were sitting in scanned card images the whole time, while the insurance module held retired pre-2020 HICNs. CMS made the MBI mandatory on claims for dates of service on or after January 1, 2020. A stale number in the plan record does not mean the current one is missing.
- You Found You Were Overpaid. The 60-Day Clock Started the Moment You Knew, Not the Moment You Act. 42 CFR 401.305 requires an overpayment to be reported and returned within 60 days of identification, defined as when a person knowingly receives or retains it. The clock starts at identification, not at a decision to look into it, which is why an audit built only to find money owed to the practice misses the exposure running the other direction.
- 85 Percent of Never-Billed Dental Work Traces to One Field: No Insurance Plan on the Patient In one de-identified practice audit, 85 percent of the never-billed work came from patients with no insurance plan attached in Open Dental, not from missing payer expertise. The practice's own report could see only 3.4 percent of that work by dollar value. It is an intake-hygiene defect, and it hides itself from the reports built to catch it.
- Are You Defaulting Every Consult to 99213? The 2021 E/M Rule Says Check the Level. Since January 1, 2021, CPT office and outpatient E/M codes 99202-99215 are leveled by medical decision making alone or by total time on the date of encounter, not history and exam. A level-2 established visit runs 10 to 19 minutes; a level-5 runs 40 to 54. A practice defaulting to one mid-level code on every oral surgery consult is very likely under-billing some of them.
- What It Actually Takes for a Dentist to Enroll in Medicare, and When It Is Worth It. An individual dentist enrolls in Medicare using form CMS-855I through PECOS; a practice entity enrolls separately using CMS-855B. Opting out instead requires an affidavit under 42 CFR 405.420 that locks in a 2-year term under 42 CFR 405.400. The choice determines whether a practice can bill Medicare at all.
- Who Actually Billed Medicare for Dental Work in 2024, and For What. 629 providers nationally billed Medicare Part B for dental or oral-maxillofacial services in 2024, split 166 dentists and 463 oral surgeons, for $8.3M paid. The top 100 collected 74.6% of it. The median provider collected $3,118.
- How Much of Your Unbilled Work Dies Every Month? The 12-Month Clock on Dental Medicare Claims. Medicare claims must be filed within 1 calendar year of the date of service under 42 CFR 424.44(a). Miss it and the claim is not just denied, it carries no appeal rights. A practice sitting on six months of unbilled medical-necessity dental cases has already lost the oldest of them, whether anyone has noticed or not.
- Reopening or Redetermination: Which One Fixes a Wrong Modifier on a Dental Medicare Claim A reopening corrects a clerical error within one year of the initial determination, no appeal required. A redetermination is a formal first-level appeal with a 120-day deadline. Noridian JE excludes nine modifiers, AQ, CR, GA, GY, GX, 22, 23, 66, and 74, from self-service reopening. Most ordinary modifiers are not on that list.
- Why E/M Claims With Modifier 25 Deny on Surgical Days, and When 57 Is the Right Modifier Modifier 25 covers a significant, separately identifiable E/M service on the same day as a minor procedure with a 0 or 10-day global period. Modifier 57 covers the E/M visit that leads to the decision for a major procedure with a 90-day global period. Using 25 on a major-procedure day is why the claim denies.
- The Payer Sent You a Virtual Credit Card. A Federal Guidance Letter Says You Do Not Have to Take It. Health plans routinely pay dental claims through virtual credit cards that carry a 2 to 5 percent card-network fee, while standard ACH electronic funds transfer carries almost none. CMS Guidance Letter GL-2022-04 confirms that under 45 CFR 162.925(a)(1), a health plan must honor a provider's request to use the adopted EFT standard instead, with no exceptions stated in the rule.
- Your Fee Schedule Can Change Mid-Contract. California Law Gives You 45 Business Days to See It Coming. California requires dental insurers to give at least 45 business days' written notice before a material change to a provider contract's claims-adjudication system, coverage policies, or fee-affecting rules takes effect, with the right to terminate before it does. Insurance Code Section 10133.65 defines what counts as material and voids any contract clause that tries to shorten it.
- CAQH Is Now DataSpring, Owned by the Payers Who Pay Your Claims. The 120-Day Attestation Clock Did Not Change. In June 2026 CAQH rebranded as DataSpring after a January 2026 shift from nonprofit to for-profit ownership by 12 health-plan-affiliated shareholders. The Provider Data Portal (formerly ProView) still requires re-attestation every 120 days, 180 for Illinois, or the profile status changes to Expired.
- Your Deposit and Your Remittance Are Supposed to Match Themselves. A Federal Rule Says How. A dental practice's EFT deposit and its 835 remittance are meant to reassociate automatically through a shared trace number. A federal operating rule, CAQH CORE 370, adopted at 45 CFR 162.1603 effective January 1, 2014, defines exactly how that matching is supposed to work, and what breaks when a bank or clearinghouse drops the data.
- Your PPO Discount Is Being Taken by a Payer You've Never Contracted With. 18 States Now Make Them Tell You. A dental PPO network contract can be leased or sold to a third-party payer, letting that unrelated company pay you at your negotiated discount without a direct contract. California's AB 954 (Cal. Ins. Code Section 10120.4, effective January 1, 2020) and an NCOIL model act adopted with opt-out rights in at least 18 states now require disclosure.
- Why Open Dental's Procedures Not Billed to Ins Report Under-Counts Your Real Number Open Dental's Procedures Not Billed to Ins report lists a procedure only if it has a fee, an active plan, and no do-not-bill flag. In one de-identified 12-month audit, it surfaced 3.4 percent of the never-billed work by dollar value. The other 96.6 percent was real, completed work the report cannot display.
- Dental Eligibility Verification Spending Hit $2.1 Billion in 2023. The Federal Standard That Was Supposed to Automate It Has Existed for Over a Decade. The X12 270/271 eligibility transaction is the HIPAA-mandated standard, codified at 45 CFR 162.1202, for checking a patient's dental coverage electronically. Despite that standard, U.S. dental practices spent $2.1 billion on eligibility and benefit verification in 2023, up 15 percent, because the CAQH Index found the automated response is often not detailed enough to trust.
- The Denial Code on a Dental Remittance Isn't Payer Discretion. A Federal Rule Defines What It Can Say. A dental remittance's denial code is not random. X12 maintains the Claim Adjustment Reason Code and Remittance Advice Remark Code lists, updated three times a year. A federal operating rule, CAQH CORE 360, requires payers, including Medicare, to use only a defined, limited set of code combinations for specific business scenarios.
- CPT 21215 Carries $4.3 Million and One Coverage Policy. Should You Bill It? CPT 21215, mandible bone graft, drew $4,338,970 from 35 billers in 2024 CMS Part B data, a large concentration for one code. It sits in a single Medicare contractor's limited-coverage policy, with a 674-diagnosis trauma-and-cancer whitelist and automatic denial for anything outside it.
- Why Dental Claim Status Is Still a Phone Call: 36 Percent Manual vs 2 Percent for Medical The 2024 CAQH Index found 36 percent of dental claim status inquiries were conducted fully manually, by phone, mail, fax, or email, versus 2 percent for medical. Dental electronic adoption held flat at 28 percent while medical reached 80 percent. The gap costs the dental industry hundreds of millions a year.
- Denied Claims Win on Appeal Far More Often Than Practices Fight Them. Here Is Why. In the most rigorously audited corner of health insurance, three out of four denied claims were overturned when someone actually appealed, and almost nobody appealed. Dental runs on the same incentive. It is not a billing problem. It is a business model, working as designed, and it depends on your front desk being too busy to push back.
- The After-Hours Revenue Leak: The Money That Walks Out Before Anyone Picks Up the Phone The single largest source of preventable revenue loss in most dental practices is the patient who called after hours, got voicemail, and booked somewhere else. It never shows up on your P&L because you never see the patient you lost. Here is the mechanism, and the four numbers to pull from your own practice to size it.
- The Five Numbers That Predict Whether Your Practice Will Hit $1M Most $500K practices and most $1M practices look identical from the outside. Same team, same chairs, same software. The durable difference is five specific numbers, not the six on your dashboard, that leak silently while your software reports everything is fine. This is the diagnostic, with the operator detail and the math on each one.
The bigger argument
The provider leak is one floor of a taller building. The reason dental keeps getting treated as separate from medicine, and why the money gets stuck, is a story about health itself. I make that argument at Health Starts From The Mouth. This site is where the operator work lives. That one is where the movement does.
The next step
If a number in here matched your practice, that leak is measurable. The 12-Month Missing Money Scan reads your last twelve months of claims and finds the money already earned but never collected. 25% of what is recovered, 20% if you prepay. No recovery, no fee.
