This specimen demonstrates a 10-claim abbreviated sample. A full Clinical Denial Pattern Audit reviews 20–50 claims selected to represent the plan’s denial distribution across condition categories, denial types, and service levels.
Claims were selected from the plan’s H2 2025 denial log to represent the three highest-volume denial categories: musculoskeletal (4 claims), behavioral health (3 claims), and cardiology (3 claims). Within each category, claims were selected across inpatient medical necessity, outpatient medical necessity, and level-of-care denial types. Administrative denials (eligibility, timely filing, coding) are excluded — they are not subject to clinical defensibility assessment.
Each claim is assessed on four dimensions: (1) whether the stated criteria actually apply to the clinical presentation; (2) whether the denial rationale addresses the specific clinical evidence rather than using boilerplate language; (3) whether the reviewer documented consideration of the clinical evidence that supports the service; and (4) whether the peer-to-peer review, if conducted, is documented with sufficient specificity to demonstrate good-faith engagement.
| # | Category | Denial Type | Service Denied | Criteria Cited | P2P? |
|---|---|---|---|---|---|
| 1 | Musculoskeletal | Med. necessity | Lumbar fusion L4–L5 (elective) | MCG SG-SU “Spinal Fusion, Lumbar” | Yes |
| 2 | Musculoskeletal | Med. necessity | Knee arthroscopy (meniscal repair) | MCG SG-SU “Knee Arthroscopy” | No |
| 3 | Musculoskeletal | Med. necessity | PT continuation beyond 12 visits (cervical) | TPA supplemental policy CP-2024-009 | No |
| 4 | Musculoskeletal | Level of care | Inpatient admission for shoulder arthroplasty | MCG “Inpatient Admission, General” | Yes |
| 5 | Behavioral health | Med. necessity | IOP continuation beyond 4 weeks (SUD) | TPA supplemental policy BH-2024-003 | No |
| 6 | Behavioral health | Med. necessity | Psychological testing (neuropsych battery) | MCG A-AC “Psychological Testing” | No |
| 7 | Behavioral health | Level of care | BH inpatient → IOP step-down (day 4) | MCG “Inpatient, Behavioral Health” | Yes |
| 8 | Cardiology | Med. necessity | Cardiac MRI (rule out ARVC) | MCG A-IM “Cardiac MRI” | No |
| 9 | Cardiology | Med. necessity | Cardiac rehab Phase II (continued) | TPA supplemental policy CP-2024-014 | No |
| 10 | Cardiology | Med. necessity | PCI (percutaneous coronary intervention) | MCG SG-CV “Percutaneous Coronary” | Yes |
A criteria mismatch occurs when the denial letter cites criteria that do not correspond to the clinical presentation, the denial type, or the plan’s own clinical policy. Mismatches are distinct from disagreements about whether criteria were met — they indicate the wrong criteria were applied.
| # | Criteria Cited in Denial | Criteria Actually Applicable | Nature of Mismatch |
|---|---|---|---|
| 3 | TPA supplemental policy CP-2024-009 (PT visit limits) | MCG “Physical Therapy, Outpatient” | Supplemental policy substituted for clinical criteria. Blanket 12-visit limit applied instead of MCG criteria that assess ongoing necessity based on documented functional progress. The supplemental policy contains no clinical assessment methodology. |
| 4 | MCG “Inpatient Admission, General” | MCG “Inpatient Admission, Orthopedic Surgery” | Generic criteria applied instead of procedure-specific criteria. General inpatient admission criteria applied to a planned surgical admission rather than the orthopedic-surgery-specific criteria that account for post-surgical pain management, mobility requirements, and complication monitoring. |
| 5 | TPA supplemental policy BH-2024-003 (IOP duration limit) | MCG A-AC “Intensive Outpatient Program, SUD” | Supplemental policy substituted for clinical criteria (BH). Same pattern as Claim 3: blanket 4-week limit applied via supplemental policy rather than MCG criteria assessing treatment response, relapse risk, and functional status. |
| 6 | MCG A-AC “Psychological Testing” (screening criteria) | MCG A-AC “Neuropsychological Testing” | Wrong criteria subcategory. Screening-level psychological testing criteria applied to a full neuropsychological battery referral. The clinical indications and medical necessity thresholds differ between screening instruments and comprehensive batteries. |
| 9 | TPA supplemental policy CP-2024-014 (cardiac rehab session limits) | MCG “Cardiac Rehabilitation, Phase II” | Supplemental policy substituted for clinical criteria. Third instance of supplemental policy substitution. The TPA’s session limit policy overrides MCG criteria that assess continuation based on documented functional improvement and hemodynamic response. |
Three of five criteria mismatches (Claims 3, 5, 9) share the same structural defect: TPA supplemental policy substituted for published clinical criteria. This is a systematic pattern, not an isolated reviewer error.

Defensible: Correct criteria applied, rationale addresses specific clinical evidence, supporting evidence considered, P2P adequately documented. Likely survives DOL audit or fiduciary proceeding scrutiny.
Questionable: Correct criteria may have been applied, but documentation gaps create ambiguity or risk. The denial might survive scrutiny but presents meaningful exposure.
Indefensible: Wrong criteria applied, or denial based on a blanket administrative policy that bypasses clinical criteria assessment entirely.
| Pattern | Description | Claims | Risk Level |
|---|---|---|---|
| 1 | Supplemental policy substituted for published clinical criteria | 3, 5, 9 | Critical |
| 2 | Wrong criteria subcategory applied to clinical presentation | 4, 6 | Moderate |
| 3 | Absent P2P documentation on policy-limit denials | 3, 5, 9 | Moderate |
Three of ten sampled denials were based on TPA supplemental policies that impose blanket service limits without any clinical assessment methodology. In each case, MCG criteria exist for the same service with clinical assessment parameters that the supplemental policy ignores. This is a design-level problem: the supplemental policies are constructed to deny services based on utilization counts, not clinical evaluation. This is the single most significant finding and the most material fiduciary exposure.
Two of ten denials applied the wrong criteria subcategory — general inpatient criteria instead of surgery-specific criteria, and screening criteria instead of neuropsychological battery criteria. This suggests either insufficient reviewer training on MCG navigation or inadequate criteria-selection oversight in the TPA’s UM workflow.
Of the six claims without P2P, three involved supplemental-policy denials where P2P was not offered because the denial was based on a hard policy limit rather than a clinical determination. The absence of P2P in policy-limit denials is structurally embedded: there is no clinical disagreement to discuss when the denial is based on a visit count, not a clinical judgment. This further supports the finding that the supplemental policies bypass the clinical UM process entirely.
The central finding of this audit is that the TPA’s utilization management program operates two parallel denial tracks: a clinical track that applies MCG criteria with varying levels of rigor, and an administrative track that applies blanket service limits through supplemental policies without clinical assessment. The clinical track, when properly applied (Claims 1, 7, 8, 10), produces defensible denials. The administrative track (Claims 3, 5, 9) produces indefensible denials by construction — not because individual reviewers made errors, but because the supplemental policies are designed to deny services based on utilization counts rather than clinical evaluation.
In a DOL audit or ERISA fiduciary proceeding, the question will be whether the plan fiduciaries knew that their TPA was using administrative cost-containment limits labeled as clinical policies — and whether that constitutes a breach of fiduciary duty. The plan sponsor’s fiduciary exposure is directly proportional to how long the supplemental-policy substitution pattern continues after this audit identifies it.
Immediate: Suspend the three supplemental policies identified (CP-2024-009, BH-2024-003, CP-2024-014) and replace them with MCG criteria-based clinical assessments for the same services.
Short-term: Conduct reviewer training on MCG criteria navigation, specifically on selecting the correct criteria subcategory for surgical admissions and neuropsychological testing referrals. Implement criteria-selection audit in the TPA’s UM workflow before the denial letter is issued.
Structural: Review the entire supplemental policy manual for additional blanket service limits. Any supplemental policy that imposes a hard utilization limit without a clinical assessment methodology should be assessed for the same defect identified in this audit.
Three of ten sampled denials were based on TPA supplemental policies that bypass the plan’s stated clinical criteria methodology. These denials are indefensible — not because the clinical judgment was wrong, but because no clinical judgment was applied. Two additional denials applied incorrect criteria subcategories. The remediation is structural: the supplemental policies must be replaced with criteria-based assessments, and reviewer training must address criteria navigation.
