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

What Does OA-B14 Mean?

OA-B14 is uncommon and appears when the one-visit-per-day rule interacts with coordination of benefits scenarios. The financial responsibility for the denied second visit may be unclear across payers.

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. Verify the rule with each payer Confirm which payer applied the one-visit-per-day limit and whether the other payer has the same restriction.
2. Redirect if appropriate If the second visit is covered by a different payer, submit to that payer with proper documentation and modifiers.

Common RARC Pairings

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

How to Prevent OA-B14

• Verify same-day visit policies with all payers in the patient's coverage chain
• Use consistent modifiers across all payer submissions for legitimate same-day encounters

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
