What documentation is required for D0274?
Bitewing codes are radiographic codes — the chart note must justify the image, not just record that it was taken. A defensible D0274 entry includes:
- Clinical indication / order rationale — caries risk, recall surveillance, pre-restorative planning, perio bone-level monitoring. "BWs taken" alone is the weak version that auditors flag.
- Patient consent and radiation discussion — confirms ALARA was honored and the patient was informed
- Image type, count, and area — explicitly "four bitewings — R and L premolar, R and L molar"
- Technique — digital sensor (or PSP/film), exposure parameters per office protocol, operator initials
- Diagnostic quality statement — note any retakes and the reason (cone-cut, overlap, motion). Non-diagnostic images that were not retaken are an audit liability.
- Interpretation by quadrant — interproximal caries, existing restorations, crestal bone levels, calculus, other findings (or "no significant findings"). Quadrant-by-quadrant beats a single "WNL" line.
- Linkage to diagnosis or treatment plan — when the bitewing supports another procedure (e.g., caries diagnosis driving D2392), reference that linkage so the imaging code stands on its own footing
- Image labels and storage — patient identifier, date, tooth/area; archived in the imaging system and accessible for claim attachment
- Provider signature
Two non-obvious points: (1) document the reason for ordering, not just the act of taking — radiograph denials disproportionately stem from notes that read like a checklist; (2) include retake / non-diagnostic image reasoning in the chart, since some payers and state boards specifically look for it.
Why does D0274 get denied?
The most common reasons D0274 is denied, downgraded, or bundled:
- Same-DOS conflict with D0210 (FMX) — by far the most common. Carriers bundle bitewings into the FMX and pay only D0210. Some carriers will deny the FMX if bitewings were billed alongside, treating the combination as unbundling.
- Frequency exceeded — patient already had a bitewing (any of D0270/D0272/D0273/D0274) within the carrier's lookback window
- Image count mismatch — four images claimed but the chart only documents two, or vice versa. Coding by image count is a hard rule; carriers downgrade D0274 → D0272 when only two images are in the imaging system.
- Insufficient documentation — note doesn't include indication, interpretation, or diagnostic-quality language. Generic "BWs taken" notes are flagged on audit.
- Same-DOS with D0330 (pano) on FMX-restrictive plans — the carrier treats pano + BWs as a constructed FMX and applies the FMX frequency rule
- Pediatric age cutoff — some Medicaid programs and pediatric plans don't reimburse D0274 below a specified age and downgrade to D0272 or deny outright
- Audit pattern: routine D0210 + D0274 same-day billing — repeated submission triggers a payer audit because the FMX is interpreted to subsume bitewings. State Medicaid and Federal programs (including IHS guidance) specifically watch for this pattern.
- Missing operator / provider attribution when state law requires named operator on radiographic exposures
What do practices ask about D0274?
What's the difference between D0272, D0273, and D0274?+
Image count. D0272 = two bitewings, D0273 = three bitewings, D0274 = four bitewings. The code follows the literal number of images captured and stored in the imaging system on that date of service. D0274 is the standard adult set (typically two premolar films and two molar films, capturing the posterior interproximal contacts bilaterally).
Can I bill D0274 and D0210 (FMX) on the same day?+
Generally no. The ADA's bundling guidance and virtually every carrier treat the full-mouth series as already including bitewings. Billing both on the same DOS will result in D0274 being denied or bundled into the FMX, and on some plans the FMX itself is denied as unbundled. Pick one: an FMX (D0210) when periapical and bitewing anatomy is needed, or four bitewings (D0274) when only interproximal/crestal anatomy is needed.
How often does insurance cover D0274?+
Most adult plans cover one bitewing set every 6–12 months; pediatric plans typically allow one every 6 months. Carriers pool D0270, D0272, D0273, and D0274 under one shared bitewing frequency, so any of those codes within the lookback window will exhaust the allowance. MetLife Federal Dental's 2026 plan, for example, limits D0274 to one set per calendar year for adults.
Can D0274 be billed more often than once a year for high-caries-risk patients?+
ADA / FDA patient-selection guidance supports bitewings every six months for documented high-caries-risk patients, and many Medicaid MCOs and some PPOs honor that schedule when the chart supports the risk classification. The chart note must include the caries-risk assessment and a clinical justification for the elevated frequency — otherwise the second set of the year will deny on frequency.
Does D0274 include the dentist's interpretation?+
Yes. The CDT descriptor is for the radiographic image and its interpretation; there is no separate interpretation code for routine bitewings. The chart note must include a quadrant-by-quadrant interpretation (caries, bone levels, restorations, other findings) to defend the code on audit. Listing only that images were taken — without findings — is the most common documentation deficiency.
Can D0274 be billed alongside a panoramic radiograph (D0330)?+
Often yes, but watch the plan. A pano captures different anatomy (jaws, sinuses, third molars, TMJs) and is a legitimate same-day pairing in many clinical scenarios. However, some carriers bundle pano + four bitewings as a constructed FMX and apply the FMX frequency limit. If the patient's plan has restrictive FMX rules, expect a downgrade.
What if one of the four bitewings was non-diagnostic?+
Document the reason (cone-cut, overlap, motion, anatomic obstruction) and the retake. If you ultimately took and stored only three diagnostic images, bill D0273 — image count is the rule. Billing D0274 with only three diagnostic images in the chart is a coding-by-image-count violation that carriers downgrade on audit.
