Policy Medical Necessity / Experimental and Investigational section

Cosmetic procedures / Not medically necessary for cosmetic indications

Cosmetic exclusions: Surgical repair of pectus excavatum when the medical necessity criteria in Section I are not met; bracing and surgical procedures to correct pectus carinatum (PC) because PC typically does not cause physiologic disturbances of the heart or lungs).

Policy lists these procedures as cosmetic

Evidence-based considerations for surgical intervention and analgesia — Evidence summaries and suggested operative indicators from literature (not explicit payer criteria):

Evidence summaries and suggested operative indicators from literature (not explicit payer criteria):

Surgical technique outcomes: Comparative outcome data indicate Nuss and Ravitch procedures generally have better outcomes than implants/Robicsek techniques; symptomatic pediatric patients with uncomplicated PE are commonly recommended for the Nuss procedure, while adults may undergo Nuss or Ravitch with consideration of adult-specific complication risks.

Johnson et al 2014

Severity metrics for surgical indication: Correction Index (CI) has been proposed as an alternative to the Haller Index (HI); some authors recommend CI ≥ 28% as an operative threshold corresponding to HI ≥ 3.25 and CI may better separate affected from control populations in select studies.CI ≥ 28% (proposed)

St. Peter et al 2011; Poston et al 2014

Cryoablation for postoperative analgesia: Intercostal nerve cryoablation during Nuss is associated with reduced hospital length of stay and lower opioid requirements compared with thoracic epidural but increases operative time; evidence is limited and heterogeneous and further RCTs are needed.

Bracing and surgical procedures to correct pectus carinatum are classified as cosmetic and are not covered for physiologic indications. The policy explicitly lists bracing and surgical correction of pectus carinatum as cosmetic because the deformity typically does not cause physiologic disturbances from compression of the heart or lungs (ICD-10: Q67.7 is listed as not covered for indications in this CPB).

Pectus carinatum is noted to be primarily a cosmetic deformity: in the vast majority of patients there is no physiologic deficit, and appearance is the primary concern. Because physiologic impairment is uncommon, interventions performed solely for cosmetic reasons may be excluded from coverage absent documented functional impairment.

The document excerpt provided is a Clinical Policy Bulletin and contains a partial description of plan benefits; it does not present an exhaustive list of exclusions. The policy history and additional information sections emphasize that the bulletin assists in administering plan benefits and is not a guarantee of coverage.

No explicit additional coverage exclusions are specified in the footer or supplemental information sections of this excerpt. External links and legal notices are provided for informational purposes only and do not alter coverage determinations.

Surgical repair of pectus excavatum performed when the policy's medical necessity criteria are not met is considered cosmetic and therefore not medically necessary. The policy lists repair for cosmetic indications as excluded when the required objective evidence (cardiac compression/displacement on echocardiography, TLC ≤ 80% predicted, exercise pulmonary function testing showing exercise intolerance, and CT demonstrating a pectus index > 3.25) is not present.

Because most patients with pectus carinatum lack physiologic symptoms and treatment is typically driven by cosmetic concerns, surgical correction may be considered not medically necessary in the absence of documented functional impairment or severe deformity.

Within the provided excerpt there are no additional explicit statements labeled as 'not medically necessary' beyond the cosmetic‑related exclusions already specified for pectus excavatum and pectus carinatum.

No codes listed

inv-18: Haller index (Pectus severity index)

DefinitionHaller index (pectus index, PI, or pectus severity index): ratio of chest width (transverse diameter) to the anterior–posterior distance between the sternum and spine at maximal depression; normal ≈ 2.54; > 3.25 considered severe for pectus excavatum.

How measuredCalculated from chest CT or MRI by dividing transverse chest diameter by anterior–posterior diameter at point of maximal depression.

Surgical threshold> 3.25 (CT demonstrates pectus index > 3.25 required for surgical repair per policy).

Notes on interpretationHigher HI indicates greater severity in pectus excavatum; may overlap with normal values in some populations and can be less accurate in non-standard chest morphologies.

inv-19: Total lung capacity (TLC)

DefinitionTotal lung capacity (TLC): the maximum volume of air contained in the lungs as measured by pulmonary function testing.

Surgical thresholdTLC ≤ 80% of predicted value (reduced lung capacity demonstrated by pulmonary function testing is a criterion for surgery).

Role in documentationPulmonary function testing showing TLC ≤ 80% predicted or exercise pulmonary function tests demonstrating exercise intolerance supports medical necessity.

inv-20: Correction Index surgical threshold

DefinitionCorrection Index (CI): percentage metric using the minimum distance between posterior sternum and anterior spine and the maximum anterior chest depth to quantify the chest wall defect (expressed as a percent).

Suggested operative thresholdCI ≥ 28% has been recommended by some authors as an operative threshold and correlates with Haller index ≥ 3.25.

Clinical noteCI may better separate affected patients from controls and may be more accurate than HI in non-standard chest morphologies.

Provider Actions / Authorization & Documentation

Prior Authorization

Prior Authorization Required for Selected Procedures

Prior Authorization Considerations for MIRPE and Cryoablation: Prior authorization may be required for minimally invasive repair of pectus excavatum (MIRPE/Nuss procedure) and for adjunctive intraoperative intercostal nerve cryoablation. When seeking authorization, include documentation of the indication for MIRPE (see medical necessity criteria) and a plan for analgesia strategy if cryoablation is proposed.

CPT 21742, 21743 (MIRPE procedures) — prior authorization may apply per plan benefits.
Intercostal nerve cryoablation — include rationale for use as adjunct to MIRPE and expected benefits (reduced LOS, decreased opioid use).

Note

Prior Authorization — Not Specified in Excerpt

Prior authorization requirements are not fully specified in the excerpted document. Providers should verify plan-specific prior authorization rules, affected CPT/HCPCS codes, and submission portals with Aetna before scheduling procedures.

No exhaustive list of prior authorization codes or explicit workflow provided in this bulletin.

Denial Risk

Failure to Meet Medical Necessity Criteria — Denial Risk

Failure to meet the medical necessity criteria outlined in this policy (for example, lack of objective evidence of cardiac compression/displacement, TLC > 80% predicted, Haller index < 3.25 and insufficient exercise pulmonary function test abnormalities) is a common reason for denial of surgical repair. Procedures performed solely for cosmetic indications (especially most pectus carinatum cases) are not medically necessary under this policy.

Denial risk when objective criteria (echocardiography, PFTs, CT-derived indices) are not documented.
Pectus carinatum is frequently considered cosmetic; surgery for PC is generally not covered unless functional impairment is demonstrated.

Note

Cosmetic Nature of Most Pectus Carinatum

Most pectus carinatum cases are primarily cosmetic. Surgical correction is generally pursued for appearance concerns; include documentation of functional impairment if asserting medical necessity.

Note that orthotic compression bracing is a non-surgical conservative option; surgery is typically reserved for selected patients with functional deficits or severe deformity unresponsive to bracing.

Note

Clinical Policy Bulletin — Administrative Notice

This Clinical Policy Bulletin is provided by Aetna to assist in administering plan benefits. It contains a partial description of plan or program benefits and does not constitute a contract or guarantee of coverage. Providers remain responsible for confirming member benefit coverage and any plan-specific administrative requirements.

Clinical Policy Bulletin — consult member’s benefit plan for coverage determinations.
This bulletin may be updated; verify effective/next review dates on Aetna resources.

Note

No Policy-Specific Authorization or Denial Triggers Stated

No policy-specific authorization or denial triggers are listed in these fragments beyond the medical necessity criteria; use the clinical criteria (objective imaging, PFTs, ECG/echo when indicated, severity indices) as the basis for authorization requests and potential denial reasons.

Authorization/denial decisions hinge on meeting the documented medical necessity criteria in this CPB.
If criteria are not met, procedure is typically considered cosmetic or investigational and may be denied.

Documentation Required

Required Clinical Documentation for Authorization

Required clinical documentation for authorization should include objective evidence of physiologic impairment and anatomical severity: CT-derived Haller index or correction index, echocardiogram showing cardiac compression/displacement if suspected, pulmonary function testing with TLC ≤ 80% predicted or exercise PFTs demonstrating reduced capacity, and ECG/echo when murmur or known heart disease is present.

CT scan report with Haller index (PI) > 3.25 for pectus excavatum or correction index ≥ 28 % as applicable.
Pulmonary function testing (TLC ≤ 80% predicted) or exercise pulmonary function test results showing restrictive physiology or reduced exercise capacity.
Echocardiogram or ECG documenting cardiac compression/displacement or to correlate cardiac findings with the deformity when cardiac signs/symptoms are present.
Operative plan specifying procedure (open versus MIRPE), planned analgesia approach (e.g., epidural, intercostal/paravertebral blocks, ketamine infusion, cryoablation), and rationale for chosen modality.

Documentation Required

Severity Indices and Documentation (Haller Index, Correction Index)

Severity indices and documentation: use CT or MRI measurements to report the Haller Index (PI) and, where appropriate, the Correction Index (CI). Include the numeric index value and imaging report; note that CI may better distinguish affected from normal in atypical chest morphologies.

Haller Index (PI) — report value; PI > 3.25 generally considered severe for pectus excavatum.
Correction Index (CI) — consider reporting CI, with CI ≥ 28% supporting operative repair in some series.
Attach representative imaging (axial CT/MR) and radiologist interpretation.

Step Therapy

Conservative Therapies and Step Approach

Conservative therapies and step approach: conservative, nonoperative options such as vacuum bell and dynamic compression systems are discussed in the literature but are considered experimental/investigational in this policy. For pectus carinatum, orthotic compression bracing is a common conservative therapy; document prior conservative management and response when applicable.

Vacuum bell and Dynamic Compression System — described in studies but considered experimental/investigational for PE in this CPB.
For pectus carinatum, document trials of orthotic compression bracing (duration, compliance, and outcomes) before surgical consideration.

Documentation Required

Analgesia Sequencing Options for MIRPE and Adjuncts

Analgesia sequencing options for MIRPE should be documented in the authorization request. Acceptable perioperative/postoperative analgesia strategies cited include thoracic epidural, intercostal or paravertebral nerve blocks, ketamine-based infusions, patient-controlled analgesia, and intercostal nerve cryoablation as an adjunct. Provide rationale for the selected approach and any expected advantages (e.g., cryoablation may reduce LOS and opioid use but can increase operative time).

List planned analgesia: thoracic epidural, intercostal/paravertebral nerve blocks, ketamine infusion, PCA, or intercostal nerve cryoablation.
If proposing cryoablation, include evidence-based rationale and anticipated impact on length of stay and opioid requirements.
