Medical record missing
The payer needs the patient's record for this service and did not get it.
Usual causes
- Prepayment review or a records request that was missed.
- Records sent without the claim identifier.
The fix
Send the complete note, orders and any reports with the claim number by the payer's method, and keep proof of delivery. Ask for reopening or reconsideration.
Appeal or corrected claim?
Respond to the records request (reopening). Appeal only if the payer refuses to reopen.
Deadline to watch
Records request window (often 30 to 45 days); appeal window from the denial.
Exact limits are in your payer contract or provider manual. When in doubt, send the correction or appeal this week.
