The ADA dental claim form, field by field

The ADA Dental Claim Form is the standard form a dental office uses to bill a patient's dental benefit plan, and its layout is the paper twin of the electronic claim. The current version is the 2024 form: 58 numbered items in ten sections. The practice management system builds it from the claim, so a denial that reads like a form error is almost always a setup error one screen upstream. This guide walks the form section by section, names the field in each that most often costs a payment, and ends with where those fields come from in OpenDental.

Field numbers and section names come from the ADA's own ADA Dental Claim Form page and its 2024 completion instructions. What carriers do with a bad field is what we see in our own offices, not a published statistic.

The form, section by section

Header information (items 1 and 2)

What goes here. Item 1 is the type of transaction: a statement of actual services, a request for predetermination or preauthorization, or a claim under the Medicaid EPSDT program. Item 2 is the predetermination or preauthorization number, if the carrier issued one.

The field that costs you. Item 2 left blank on the real claim. The office got a predetermination, the carrier issued a number, and the claim for the crown goes out without it, so the carrier adjudicates as if the estimate never happened. The fix is a rule: whoever posts the response records the number the same day.

Insurance company or dental benefit plan information (items 3 and 3a)

What goes here. The name and address of the payer receiving this claim and, new on the 2024 form, its payer ID (3a).

The field that costs you. A stale claims address or a missing payer ID sends the claim to a mailroom instead of an adjudicator, and the office finds out when nothing posts. This is carrier-list hygiene: one record per payer, current address and payer ID, duplicates merged.

Other coverage (items 4 through 11a)

What goes here. Whether the patient has other dental or medical coverage and, if so, the other subscriber's name, birth date, ID, and group number, plus the other plan's name and payer ID. On a primary claim this describes the secondary plan; on a secondary claim, the primary.

The field that costs you. Coordination of benefits. Item 4 left blank when the carrier's records show a second plan means a questionnaire to the patient and a hold. A secondary claim sent without the primary's explanation of benefits is the other failure; the ADA instructions say to attach the primary EOB and note the primary paid amount in remarks. The fix lives in insurance verification, where "any other coverage?" is asked every time.

Policyholder or subscriber information (items 12 through 17)

What goes here. The subscriber for the plan in item 3: name and address, date of birth, gender, subscriber ID, group number, and employer.

The field that costs you. Item 15, the subscriber ID, then item 13, the date of birth. Carriers match on these before reading a single procedure. A child's name in the subscriber slot, two digits transposed, or a Social Security number where the plan now issues a member ID, and the claim comes back as patient not found. Enter the subscriber exactly as the card prints it, and re-verify each benefit year.

Patient information (items 18 through 23)

What goes here. The patient's relationship to the subscriber (self, spouse, dependent child, other), name, address, date of birth, gender, and an optional account number. Item 19 is reserved for future use and stays blank.

The field that costs you. Item 18. Mark self for a dependent and the carrier looks for the child on a roster it will never be on. It is set once and rarely looked at again; check it at verification.

Record of services provided (items 24 through 35)

What goes here. Ten service lines: procedure date (24), area of the oral cavity (25), tooth system (26, always JP), tooth number (27), surface (28), procedure code (29), diagnosis pointer and quantity (29a, 29b), description (30), and fee (31). Below the lines: total fee (32), missing teeth (33), diagnosis codes (34, 34a), and remarks (35).

The fields that cost you. This section produces more denials than the other nine together, and items 25, 27, and 28 lead. Which of quadrant, tooth, and surface a code needs is not a judgment call; the ADA publishes a code-by-code table alongside the form. Scaling and root planing (D4341, D4342) takes the quadrant code (10 upper right, 20 upper left, 30 lower left, 40 lower right) and the teeth treated. A posterior composite (D2391) takes the tooth and the surfaces, written with no spaces: MOD. A crown (D2740) takes the tooth only. An adult prophy (D1110) or periodontal maintenance (D4910) takes none of them.

Item 29, the procedure code, must come from the CDT version in effect on the procedure date. A claim sent under a code deleted in January is rejected before a human sees it, so loading the new CDT codes belongs on the calendar before the first claim of the year. Item 31, the fee: the ADA's position is to report the dentist's full fee, not the contracted PPO amount. An office that loads a PPO schedule as its office fee under-reports on every claim, one quiet way an unreviewed fee schedule lowers collections. Item 35, remarks, carries the narrative for a by-report code, the ones ending in 999. The ADA notes that an entry in remarks may prompt review by a person, so write the sentence that answers the question and stop.

Authorizations (items 36 and 37)

What goes here. The patient's consent to the treatment plan and its cost (36), and the subscriber's authorization for benefits to be paid directly to the dentist (37). The PMS prints Signature on File in both when the office holds one.

The field that costs you. Item 37. Without assignment of benefits the carrier may pay the subscriber, and the office is now collecting the insurance portion from someone who has already spent it. The usual cause is a new patient whose intake forms were never scanned.

Ancillary claim and treatment information (items 38 through 47)

What goes here. Place of treatment (38), enclosures such as radiographs (39), the date of the patient's last scaling and root planing (39a, new on the 2024 form), orthodontics (40 to 42), prosthesis replacement and prior placement date (43, 44), and accident information (45 to 47).

The field that costs you. Item 38 takes a two-digit place-of-service code: 11 is office, 22 is outpatient hospital, 02 is teledentistry. A hospital case sent under 11 is denied. Item 43 is the other: mark a crown as an initial placement when it replaces one from six years ago, and the carrier holding the old claim will ask. Answer yes and give the prior date in 44.

Billing dentist or dental entity (items 48 through 52a)

What goes here. The name and address of the dentist or entity submitting the claim, its NPI (49), license number (50), SSN or TIN (51), phone (52), and any legacy payer identifier (52a).

The field that costs you. The pair in 49 and 51. A group bills under a Type 2 organization NPI and the entity's TIN; the ADA instructions spell that out. A Type 1 individual NPI next to the corporation's TIN, or the reverse, is a mismatch against what the payer credentialed, and it holds the claim. It happens after an ownership change, a new associate, or a location never enrolled under the group.

Treating dentist and treatment location (items 53 through 58)

What goes here. The treating dentist's certification (53), a box for a locum tenens dentist (53a, new on the 2024 form), the treating dentist's Type 1 NPI (54), license (55), the treatment location's street address (56, not a PO box), specialty code (56a), phone (57), and any legacy ID (58).

The field that costs you. Item 54. The treating dentist has to be the person who did the work, with an NPI the payer has credentialed at the address in 56. In groups, it is an associate credentialed at office A treating at office B; in a solo office, a substitute covering a vacation, the case 53a was added for.

The form does not cause the denial. The setup behind it does. The form is only where you find out.

The denials this form causes, and where the mistake was made

How is the form produced in OpenDental?

MyDentalForce integrates with OpenDental today, so that is the system we describe. In OpenDental nobody types into the form. A claim is created from completed procedures in the Account module, and the ADA form, printed or electronic, is populated from that claim. Every field above traces back to a setup screen.

• Lists, Procedure Codes: the source of item 29, and where each January's CDT update is loaded
• Setup, Fee Schedules, and the fee schedule attached to each plan: the source of item 31
• The Edit Insurance Plan window: carrier, payer ID, group number, employer, relationship to subscriber, and plan order, which fill items 3 through 18

The provider side comes from Lists, Providers, where each dentist's NPI, state license, and SSN or TIN live. Tooth, surface, and quadrant are whatever was on the procedure when it was set complete in the Chart module; the claim only copies them. Place of service and the predetermination number sit on the claim's General tab. The printed form version is chosen under Setup, Family/Insurance, Claim Forms; the default should be the 2024 form.

Two OpenDental features catch most of this early: the preference to require claims to have no missing data, which stops a claim from being created when a procedure lacks a tooth number, and the Send Claims window in the Manage module, which validates every electronic claim before it goes and lists what is missing. Use both. Then work the pattern: when the same field fails twice in a month, stop fixing claims and fix the screen that fed it.

One office or nine, the same form

In a single practice the biller who sees the denial can open the setup screen the same afternoon; the risk is that the fix stays in one person's head. Across several offices the same denial repeats quietly at one location, and the group sees it only as a widening gap between that office's production and collections, one of the KPIs worth tracking per office. That is what our Billing & Claims view is built for: a cross-office billing worklist of claims, unsent claims, and procedures that still need billing, next to production and collections per office reconciled to OpenDental, so a billing team can see which office's denials are a setup problem. It is a worklist, not a billing service. When a denial has become an aging patient balance, Balance Outreach points the same daily list at collections.

Print the ADA completion instructions once, mark the items above, and check them against your last twenty denials. Most find two or three setup fixes that end a category of denial. When you want that pattern visible across every office, book a walkthrough and we will show Billing & Claims on your own offices' claims.
