'Always Investigational' designation implies noncoverage — PA will not make payable
Moda labels many listed codes and services as 'Always Investigational', which the document indicates are considered investigational and therefore not covered — prior authorization would not render these payable.
- 'Always Investigational' entries indicate the payer considers the service investigational and not covered; claims billed with these codes should be expected to be denied regardless of prior authorization
Investigational designation listing — many codes shown without PA details
The document enumerates numerous tests and procedures designated Always Investigational; these listings do not provide prior authorization workflows or PA requirements in the cited chunks.
- Multiple molecular and genomic tests (cell‑free DNA, ctDNA panels, large NGS panels) and proprietary assays are listed as Always Investigational without PA instructions
Investigational code list (partial) — expect denials if billed
The partial investigational code list explicitly marks numerous CPT/HCPCS and temporary codes as Always Investigational; providers submitting these codes should expect investigational denials per the policy.
Skin substitute application codes (G0681–G0684) — listed; many entries Always Investigational
G0681–G0684 (application of non‑sheet form HCT/P skin substitutes) are listed with service descriptions and Moda marks many related entries in this segment as Always Investigational; billing uses specified wound surface area increments.
- G0681: non‑sheet HCT/P skin substitute up to 100 sq cm; first 25 sq cm or less — listed (Always Investigational noted in segment)
- G0682: each additional 25 sq cm — billing as add‑on
- G0683/G0684: larger wound surface area increments (first 100 sq cm and each additional 100 sq cm) — designated Always Investigational in these chunks
Investigational code designation — no PA workflows specified; likely denials
Many codes in the document are labeled 'Always Investigational,' indicating noncoverage; the policy does not define prior authorization pathways or provider documentation requirements for these investigational entries in the cited chunks.
- Providers should treat codes annotated 'Always Investigational' as not covered and anticipate denials if billed
- No prior authorization workflow or documentation guidance is provided for these entries in the cited sections
Sample investigational T‑codes (0453T–0456T) — Always Investigational
The policy lists sample investigational procedure codes (for example 0453T–0456T range) and marks them Always Investigational in the excerpt.
- 0453T, 0454T, 0456T: endovascular aortic counterpulsation ventricular assist system entries — ExceptionsNotes = Always Investigational
Cosmetic procedure codes (dermabrasion/chemical peel/etc.) — Always Cosmetic
The policy enumerates multiple aesthetic procedure codes (dermabrasion, chemical peel, blepharoplasty, rhytidectomy) that are designated Always Cosmetic and therefore not covered for medical necessity.
- 15781–15789 and related codes: dermabrasion and chemical peel codes annotated Always Cosmetic
Investigational/coverage status listings — many codes marked investigational; no PA steps provided
This portion of the document lists many services (CPT/HCPCS/Q/S codes) marked Always Investigational or other exceptions, and does not provide explicit prior authorization instructions in the cited chunks.
- Numerous codes across categories are shown with ExceptionsNotes = Always Investigational; no PA instructions are included in these entries
Investigational Q‑codes — many wound/biologic products marked Always Investigational
A wide range of HCPCS Q‑codes for biologic/skin/amniotic/wound products (for example Q4143–Q4160 series) are listed with ExceptionsNotes = Always Investigational in the policy.
Terminology and Designation Key
OpenPayer is powered by Trek Health's payer performance platform. Trek continuously ingests, validates, and normalizes Transparency in Coverage data alongside payer policies and other commercial payer data to create a structured payer intelligence foundation. OpenPayer uses this foundation to deliver personalized search results, dynamically generated policy pages, and tailored policy monitoring based on each user's payers, specialties, billing codes, and areas of interest. The same intelligence powers broader payer performance workflows, including reimbursement benchmarking, contract evaluation, payer negotiations, and financial decision-making.
