Filing deadlines, appeal addresses, and policy criteria in this template reflect typical payer behavior at publication. Blue Cross Blue Shield updates policies frequently and plan-level rules vary by employer group, state, and line of business. Always cross-check the specific deadline and filing address on your EOB, and confirm current Blue Cross Blue Shieldmedical-policy language through the payer’s provider portal before submitting an appeal. Overturn-rate language below reflects AAPC-reviewer consensus, not payer-published statistics.
When to use this template
BCBS CO-16 denials in dermatology are concentrated on biopsy and excision claims where multiple lesions are billed on the same day. BCBS claim scrubbers require specific documentation per lesion: site, size, modifier, and diagnosis linkage.
Attachment checklist
- Ordering provider note with clinical indication
- Prior workup or conservative-care documentation
- Payer medical policy reference citing met criteria
- Retroactive authorization request (if applicable)
Missing any one of these is the single largest cause of appeal denials. Build a pre-filing checklist before you submit.

How long do I have to file a CO-16 appeal with Blue Cross Blue Shield?
180 days from the initial adjudication date for most Blue Cross Blue Shield plans. Corrected claims (for administrative fixes like missing modifiers or auth numbers) have a different and usually longer window. Always confirm the specific deadline on the EOB for your claim.
What is the typical overturn rate for this denial type?
90+ percent when modifiers and sizing are corrected. Success depends heavily on documentation completeness and whether the clinical criteria in Blue Cross Blue Shield's medical policy are matched point-by-point in the appeal.
Should I file this as a corrected claim or a formal appeal?
CO-16 is typically a corrected-claim fix, not a formal appeal. Identify the specific RARC code on the EOB that pinpoints the element to fix, correct it, and resubmit with frequency code 7.
Can I reuse this template for other payers?
