3D Rendering Coverage Rules

Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

3D rendering coverage rules

Covered with criteria — separate reimbursement for 3D radiology rendering is generally not allowed.

3D radiology services (including CPT 76376 and 76377) are considered elective visual enhancements and are included in the reimbursement for the primary imaging study; not eligible for separate reimbursement; modifiers will not override these edits.

Exception: Separate reimbursement may be allowed only when provider, state, or federal contracts and/or mandates explicitly require separate payment.

There are no exemptions to this policy.

Prior Authorization and Contractual Exceptions

Prior Authorization

Prior authorization and contractual exceptions for 3D radiology

3D radiology services are included in the reimbursement for the primary imaging study and are not eligible for separate reimbursement except when a provider, state, or federal contract or mandate explicitly requires separate payment. Services must also meet authorization and medical necessity guidelines appropriate to the procedure and diagnosis.

Separate reimbursement only allowed when provider, state, or federal contracts and/or mandates indicate otherwise.
Services must meet applicable authorization and medical necessity requirements.

Key Definitions

3D radiology (rendering of imaging studies) — definition and purpose

Term3D radiology (rendering of imaging studies)

DefinitionThe reconstruction of multiple thin sections of images into 3D images which can display anomalies or structures and enhance visualization of pathology.

PurposeTo display anatomical anomalies or structures and enhance visualization of pathology for diagnostic review.

ScopeApplies to rendering derived from modalities that produce thin-section images (e.g., CT, MRI) as part of the imaging study, and is considered part of the primary imaging reimbursement unless contract or mandate specifies otherwise.
