Billing Steps, Prior Authorization, and Contacts
Use listed procedural modifiers to permit separate reimbursement
If a Once in a Lifetime Procedure must be submitted more than once during a patient's lifetime, report the procedure with one of the listed procedural modifiers (53, 55, 56, or 58) so each submission will be considered separately for reimbursement.
- Allowed modifiers: 53 (Discontinued procedure); 55 (Postoperative management only); 56 (Preoperative management only); 58 (Staged or related procedure or service by the same physician)
Append anatomical modifiers (RT/LT etc.) when applicable
Use anatomical modifiers when applicable; Medicaid considers a claim incomplete without an anatomical modifier if one applies to the service.
- Common side modifiers: RT (Right side) and LT (Left side) — must be used when applicable.
Confirm Trading Partner Account reversals/adjustments via confirmation message
When reversing or adjusting a claim in a Trading Partner Account, select the appropriate option on the Reverse Claim Tab and confirm the action is complete by viewing the confirmation message.
- Verify completion by viewing the system-generated confirmation message before exiting the reversal workflow.
Select the appropriate reverse-claim option (adjust vs. reverse only)
Choose the correct reversal workflow: reverse and create a new claim (adjust and resubmit) or reverse only; each produces a different confirmation and has different follow-up options.
- Option 1 — Reverse and create a new claim: correct and resubmit; confirmation shows original claim number followed by A# (e.g., A1).
- Option 2 — Reverse only: returns paid funds; confirmation shows original claim number followed by R1; no further adjustments allowed.
Provide complete documentation with prior authorization requests
Submit complete, valid prior authorization requests with all required documentation; incomplete or missing documentation can prevent review and result in denial and a required resubmission.
- Use the new DME PA request form for services starting May 1, 2017 when applicable.
- Check the Suppliers Idaho MMIS Provider Handbook and IDAPA 16.03.09.750-779 for documentation requirements.
