UHC CO-97 Bundling Denials in OB/GYN Global Package
Payment adjusted because the benefit for this service is included in another. Copy-paste appeal letter with documented overturn rate and attachment checklist for UnitedHealthcare in OB/GYN.
Verify before filing
Filing deadlines, appeal addresses, and policy criteria in this template reflect typical payer behavior at publication. UnitedHealthcare 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 UnitedHealthcaremedical-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
UHC CO-97 bundling denials in OB/GYN center on the global obstetric package (CPT 59400, 59510, 59610, 59618). The global package covers routine antepartum care (typically 13 prenatal visits), delivery, and 6 weeks of postpartum care. Services that appear to be included but are actually separately billable trigger CO-97 denials when the billing doesn't clearly distinguish them.
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-97 appeal with UnitedHealthcare?
180 days from the initial adjudication date for most UnitedHealthcare 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?
70-80 percent with proper ICD-10 coding and modifier. Success depends heavily on documentation completeness and whether the clinical criteria in UnitedHealthcare's medical policy are matched point-by-point in the appeal.
Should I file this as a corrected claim or a formal appeal?
CO-97 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?
The structure works for any payer, but the filing address, deadline, and policy references are specific to UnitedHealthcare. Check our other templates for payer-specific versions; we have 50+ payer/code combinations in the directory.
