The full path
Stage by stage
1–3. Before the visit
Scheduling is where revenue integrity starts. Capturing the correct subscriber ID, plan, and demographic data here prevents more denials than any downstream control. Eligibility and benefits (270/271). Your system sends a 270 inquiry, and the payer returns a 271 with information such as coverage status, plan type, and cost-sharing. For dental treatment planning, the 271 may not include the full breakdown of benefits. Staff may need the remaining annual maximum, coverage percentages by service class, procedure history, waiting periods, and any missing-tooth clause. Some of that information requires a portal or phone inquiry. Check eligibility at scheduling and again near the visit when appropriate, and retain the response or verification record. See Verify eligibility and benefits. Predetermination (for major work). A predetermination is an inquiry submitted before treatment, often using an 837D identified as a predetermination request with supporting clinical documentation. It returns the plan’s estimate, but it is not a payment guarantee. Final adjudication applies eligibility, remaining maximums, and frequency limits as of the date of service.1 A preauthorization is different because some plans require it before specified services are payable. Practices often request predeterminations for crowns, periodontal surgery, prosthodontics, and orthodontics to support a clearer patient estimate. See Get predeterminations.4–5. The visit
At the visit, two operational steps affect the later claim:- Point-of-care collection of the estimated patient portion. Annual maximums, coverage percentages, and alternate benefits can leave a substantial patient balance. Collecting an accurate estimate at the visit reduces later statement work.
- Documentation supports every downstream step. The chart, radiographs, periodontal measurements, and other records should support the reported CDT code and provide evidence for an attachment request or audit.
6–8. Turning care into a claim
Coding. Dental claims use CDT, the ADA-maintained procedure code set. CDT codes consist of a “D” and four digits, with tooth, surface, and quadrant information carried in related claim fields where applicable. Diagnosis-code requirements depend on the payer and claim pathway. See CDT & the 837D. Coding is an exercise of clinical judgment, and in the DSO structure it belongs to the PC. The dental support organization (DSO) can employ billers and provide the systems; it should not determine what codes are assigned. See What a DSO can and can’t do. Charge entry puts the coded visit into the practice management system (PMS) ledger. Scrubbing and attachments. The scrubber validates against payer-specific edits before submission. This is also where supporting documentation gets staged: dental payers routinely require radiographs, perio charts, narratives, or photos before they will adjudicate crowns, scaling and root planing, or implants. Today that mostly means uploading to an attachment service and carrying its reference number on the claim; a HIPAA standard (the X12 275, compliance May 2028) is replacing that workaround.2 A claim submitted without a required attachment is a delay you built yourself.9–10. Submission and acknowledgment
The 837D transaction carries the claim to the payer through a clearinghouse. Three acknowledgments can come back:
A 277CA rejection means the claim did not pass front-end processing and was not adjudicated. Correct it promptly and resubmit within the filing limit.
11. Adjudication
The payer applies member eligibility, the plan’s benefit design, the contracted fee schedule, its clinical policy, and coordination of benefits, then determines: allowed amount, payer liability, patient liability, and any denial. Benefit design plays a major role in dental adjudication. Remaining annual maximums, frequency limits, waiting periods, missing-tooth clauses, and alternate-benefit provisions can reduce payment without indicating a claim defect. See Denials vs downgrades.12–13. Remittance and payment
The 835 explains the determination line by line. The payment arrives separately, by EFT, paper check, or virtual credit card. The 835 and the payment are different objects and they do not map one-to-one. One deposit can cover several remittances. Reassociate them using the TRN trace number, not by matching dollar amounts. See The 835.14. Posting
Payments, contractual adjustments, and patient responsibility are recorded against the claim. Auto-posting handles the clean lines; an exception queue catches unmatched claims, takebacks, interest, and secondary transfers. Every dollar of difference between billed and paid is explained by a group code + CARC (+ RARC) triple:
During posting, classify each reduction as a claim defect, contractual adjustment, alternate benefit, or benefit limitation. A composite paid at an alternate allowance, a frequency-limited cleaning, or an exhausted maximum generally follows the plan terms rather than an appealable error. Move any valid patient responsibility to the ledger only when the contract and financial consent permit it.
15. Denials
Lines denied for a stated defect, such as a missing attachment, terminated coverage, or missing required preauthorization, go to the denial queue rather than an automatic write-off. Correct and resubmit when the claim had bad data or missing documentation. Appeal when the submitted claim was supportable and the payer’s determination appears wrong. See Work the denial queue.16–17. The patient balance
Valid PR amounts move to the patient ledger and statement cycle. Maximums and alternate benefits can create substantial patient balances, so timely and understandable statements matter. If the patient overpaid because the estimate exceeded final responsibility, the practice may owe a refund and may face a statutory or contractual deadline. See Patient refunds and credit balances.How long it takes
Total for a clean claim: roughly 20–40 days. For a claim held for documentation or appealed: 90–180 days, at meaningfully higher cost.
Where money leaks
Ranked by how much dental revenue they typically cost:- Verification failures: the treatment plan did not account for a remaining maximum, frequency limit, or waiting period
- Attachment failures: required documentation was not sent or could not be matched to the claim
- Alternate benefits posted as write-offs: a reduction was classified incorrectly instead of handled under the contract and patient-consent terms
- Credentialing gaps: services were billed before the applicable provider or location effective date, a common acquisition-transition risk
- Timely filing: charge-entry delay or a claim left in a rejection loop
- Unworked denials: denied claims were not reviewed before appeal or resubmission deadlines
- Unbilled visits: completed treatment never became a claim
- Underpayments: the payer used a lower allowance or leased-network fee schedule and the variance was not detected
- Patient balances written off instead of collected
