CO-B14: Only One Visit Per Physician Per Day Covered

What Does CO-B14 Mean?

CO-B14 is the standard pairing, indicating the additional same-day visit is denied as a contractual write-off. The payer reimburses only one visit per physician per day under the contract, and the provider must absorb the cost of the second encounter unless it can be justified with modifiers and documentation. The patient cannot be billed for the denied visit.

CARC B14 enforces a per-physician-per-day visit limit. The payer has already reimbursed one visit or consultation by the same physician on the same calendar day, and this claim represents an additional encounter that exceeds the coverage allowance. This is a frequency-based denial, not a clinical determination — the payer is applying a rule that restricts payment to one physician encounter per day, regardless of the clinical circumstances.

The most common scenario is a billing system artifact: the same patient encounter is split into two separate claims due to a data entry error, a time-based code that generated a second visit record, or services rendered across morning and afternoon sessions that should have been billed as a single encounter. In these cases, consolidating the services under one visit and rebilling resolves the issue without an appeal.

However, B14 also catches legitimate clinical scenarios where a patient needs to return to the same physician on the same day — post-procedure complications, acute symptom changes, or emergency returns. In these cases, the second visit is medically necessary and should be billed with the appropriate modifier. Modifier 76 (repeat procedure by same physician), modifier 25 (significant, separately identifiable E/M service), or modifier 59 (distinct procedural service) can signal to the payer that the second encounter was clinically justified. The key is providing separate documentation for each encounter with clear medical necessity.

Common Causes

How to Resolve

Determine whether the second encounter was a billing error or a clinically necessary separate visit, then consolidate or resubmit with appropriate modifiers and documentation.

1. Consolidate or separate If the services should have been one visit, consolidate. If two visits were necessary, prepare separate documentation for each with clear medical necessity.
2. Resubmit with modifiers For legitimate two-visit scenarios, resubmit the denied claim with modifier 76, 25, or 59 as appropriate, along with separate progress notes for each encounter.
3. Appeal if denied again If the payer denies the modified claim, file a formal appeal with both encounter notes and a narrative explaining the clinical justification for the separate visit.

Common RARC Pairings

The RARC code tells you exactly what triggered the CO-B14:

How to Prevent CO-B14

• Consolidate same-day services into a single encounter whenever clinically appropriate to avoid B14 denials
• When separate same-day visits are necessary, append appropriate modifiers at the time of initial billing
• Implement billing system alerts that flag multiple same-day encounters by the same physician before claim submission
• Document a separate complete progress note for each same-day encounter with clear medical necessity

General Prevention

• Consolidate same-day services into a single encounter whenever clinically appropriate instead of creating separate visits
• Use modifiers 76, 77, or 25 when legitimate multiple same-day encounters are medically necessary
• Document clear medical necessity for any same-day return visit in a separate progress note
• Implement billing system edits that flag multiple same-day encounters by the same physician before claim submission
• Train providers on payer-specific rules for same-day visit billing and proper modifier usage
