What CARC B14 actually means

CARC B14 denies a second visit by the same physician on the same day — plan rule. If two visits were clinically necessary and distinct, appeal with encounter notes showing the medical need for separate encounters and appropriate modifier (25 or 27).

Common root causes

  • Same-physician same-day visit limit hit.

Prevention checklist

  • Same-day visit rules enforced at scheduling; modifier 25/27 used when clinically distinct.

Appeal strategy — step by step

Most CARC B14 denials clear faster with the right remediation than with a formal appeal. Work the steps in order and escalate only when a lower-effort path has been ruled out.

How QuickRCM prevents CARC B14

QuickRCM catches the root causes above before the 837 leaves the clearinghouse:

  • Claim-scrub rules fire on every root cause listed above — the scrub references the same X12 CAS segment logic that drives the denial, so what the payer checks, QuickRCM checks first.
  • When a denial lands, QuickRCM routes it to the correct worker with the documentation bundle already attached (op note, LCD citation, modifier rationale, EOB, primary 835).
  • Appeal templates tuned to each CARC (including this one) pull the supporting facts from the claim and fill the bracketed fields automatically.

How do I resolve a CARC B14 (CO-B14) denial?

Start with the most common root cause: Same-physician same-day visit limit hit. First step: Appeal with notes documenting medical necessity for each visit. See the full remediation and appeal checklist on this page before filing a formal appeal.

Is CARC B14 patient responsibility?

No — CARC B14 is typically carried under CO (Contractual Obligation) or OA (Other Adjustment), which means it is the provider's responsibility, not the patient's. Do not bill the patient unless the 835 CAS group code is PR.

What does CARC B14 look like on an EOB or 835 remittance?

On the 835 ERA, CARC B14 appears in Loop 2110 CAS segment as "CAS*CO*B14*{amount}". On a paper EOB the same code prints in the Adjustment/Denial Reason column with the X12 description: "Only one visit or consultation per physician per day is covered." — usually paired with one or more RARC remark codes in the same remittance line for additional context.

Can CARC B14 be appealed successfully?

Yes — when the root cause does not apply to the specific claim. Overturn rates are strongest when the appeal cites the X12 definition, the payer's own published policy, and documentation that rebuts the payer's rationale. The sample appeal language block above is a starting point; always adapt it to the payer's reconsideration form.
