ALL of the following
- Implementation note: These are wording and structural clarifications; they do not replace the detailed measurable criteria found in the full policy document.
Providers should consult the full policy to confirm all documentation, measurement, and prior authorization requirements.
Coverage under this policy is governed by the member's applicable coverage documents and by state and federal requirements. Decisions about benefits and payment are subject to the terms, conditions, exclusions and limitations of the member's evidence of coverage, certificate of coverage, policy or contract of insurance. When state Medicaid provisions conflict with this policy, the state Medicaid requirements take precedence.
This clinical policy is intended to serve as a guide to medical necessity to assist in coverage determinations and administration of benefits. It does not constitute a contract or guarantee of payment or clinical outcomes. Explicit statements that a service is not medically necessary (NMN) and the specific conditions under which NMN applies are contained in the main criteria sections of the policy; providers should refer to those criteria for definitive NMN language when preparing requests or supporting documentation.

Provider Actions, Authorization & Documentation
Prior Authorization & Coverage Verification
Prior Authorization Required — Review policy and verify coverage before submission. Providers must confirm member eligibility and benefits, obtain any required prior authorization from Arizona Complete Health, and document the authorization number on claims to avoid delays or denials.
- Verify member plan benefits and eligibility prior to scheduling.
- Obtain and record prior authorization from Arizona Complete Health when required.
- Include the authorization number on all claims and encounter submissions.
Documentation Expectations
Documentation must support medical necessity and compliance with state and federal requirements. Maintain complete clinical records including history, examination findings, diagnostic test results, prior conservative therapy (if applicable), and photographic documentation when relevant. Documentation should be readily available for audit and peer review.
- Clinical notes detailing symptoms, pain, functional impairment, or psychological impact.
- Relevant diagnostic studies and measurements (e.g., breast measurements, imaging reports).
- Records of conservative management and duration, when required by criteria.
- Pre- and post-operative photographs when clinically appropriate.
- Retention of prior authorization approvals and correspondence.
Provider Action & Operational Alerts
Provider responsibilities and operational alerts: follow plan-specific submission requirements and timelines, bill using applicable CPT/HCPCS codes per policy, and ensure claims are accurate and complete. Failure to meet the policy criteria or submit required documentation may result in claim denial or requests for additional information.
- Ensure coding matches the service rendered and the medical record.
- Respond promptly to requests for additional documentation or peer review.
- Be aware that state Medicaid rules or Medicare NCDs/LCDs supersede policy when applicable.
General Denial Risk
Denial Risk — Claims may be denied if medical necessity criteria are not met, prior authorization was not obtained when required, documentation is incomplete, or services fall outside coverage limits. Providers should review the full clinical policy and member coverage documents before proceeding.
- Missing or insufficient clinical documentation to support medical necessity.
- No prior authorization on file when required.
- Services not covered under the member's specific benefit plan or excluded by state/Medicare rules.
Background and Evidence Base
This policy was developed using current standards of medical practice and a review of evidence-based guidance and literature. Key sources referenced include the American Society of Plastic Surgeons (ASPS) evidence-based guideline and ASPS recommended insurance coverage criteria, the American College of Obstetricians and Gynecologists (ACOG) committee opinion on breast and labial surgery in adolescents, UpToDate summaries, and selected peer-reviewed studies and clinical references. The policy reflects the judgment of experienced clinicians and available peer-reviewed medical literature to inform medical necessity determinations for reduction mammoplasty and gynecomastia surgery.
