CO-170Contractual Adjustment
Payment denied when performed by a provider of the same specialty
What this code means
Two providers with the same specialty billed for the same service on the same day. Insurers typically pay only one provider per specialty per day.
What to do next
Verify whether both providers genuinely performed separate services. If so, ask your provider to add a modifier or documentation explaining the separate services. If it was an error, ask for a corrected claim.
Appeal outlook: Moderate with documentation
