How to resolve this denial, step by step

  1. 1

    Confirm the actual location where the service was rendered from scheduling/registration records.

  2. 2

    Compare to the POS code billed.

  3. 3

    If mismatched due to data entry, correct the POS code and resubmit.

  4. 4

    If the service has a POS-specific restriction (e.g., incident-to requiring POS 11), confirm all conditions for that billing method were actually met before resubmitting under that POS.

  5. 5

    Document the POS verification outcome.

  6. 6

    Escalate to Registration/Scheduling if a specific location is consistently mis-coded.

Then choose the correct disposition

Corrected claim

for POS data-entry errors.

Compliance escalation

if there's a suggestion to bill a facility-based service as office- based (or vice versa) merely to obtain a more favorable payment rate without matching the actual encounter location.

Stop and escalate when

  • Pattern suggesting POS is being selected for payment-rate advantage rather than actual encounter location (compliance issue).

What Needs to Be Corrected

  • Claim correction: If the POS code was simply mis-keyed relative to the actual encounter location, correct and resubmit.
  • Upstream correction: If registration/scheduling consistently mis-records encounter location for a given service line or provider, that workflow needs correction.

Do Not Do This

  • Do not misrepresent the place of service to obtain a higher (e.g., non-facility) payment rate.
  • Do not bill incident-to under POS 11 if the service was actually rendered in a hospital or SNF setting.
