OA-133 Denial Code: Disposition pending further review
The line is parked pending review — the payer must later reverse and finalize it. Not a denial; a hold.
Why OA-133 happens
- ●Payer-side review (medical, COB, or fraud screening) in progress
How to fix a OA-133 denial
- 1
Calendar a follow-up (30 days); the payer owes a corrected adjudication
- 2
Escalate through provider relations if the pend ages past state prompt-pay limits
How to prevent it
Work pended claims as a distinct AR bucket so they don't age silently.
