TL;DR: Aetna, a CVS Health company, modified CPB 0411 covering bone and tendon graft substitutes and adjuncts, effective September 26, 2025. Here's what billing teams need to do.
This update to the Aetna bone and tendon graft substitutes coverage policy touches over 640 CPT codes and 71 HCPCS codes — a code set this broad means almost every orthopedic, spine, and wound care practice billing Aetna has exposure here. CPB 0411 in the Aetna system governs coverage for everything from spinal allografts (CPT 20930, 20931) to calcium phosphate injections (CPT 0707T) to platelet-rich plasma procedures (CPT 0232T). The covered-versus-not-covered line in this policy draws hard distinctions, and billing the wrong side of it will generate claim denials fast.

Aetna Bone and Tendon Graft Substitutes Coverage Criteria and Medical Necessity Requirements 2025
The Aetna bone and tendon graft substitutes coverage policy under CPB 0411 splits codes into three distinct buckets: covered when selection criteria are met, not covered for indications listed in the CPB, and related codes used in conjunction with procedures addressed by the policy.
The "covered when selection criteria are met" designation is the one your billing team needs to focus on first. This isn't blanket coverage. Aetna requires that specific medical necessity criteria be satisfied before reimbursement applies. For spinal allografts, CPT 20930 (morselized allograft for spine surgery) and CPT 20931 (structural allograft for spine surgery) fall into this covered group — but "covered if criteria are met" means documentation must support that the criteria were actually met. Thin documentation equals claim denial.
Calcium sulfate antibiotic bead procedures sit in their own group. CPT codes 0707T, 11981, 11982, 11983, and add-on codes +20700, +20701, and +20702 all map to this designation. Prior authorization requirements may apply for these codes under specific Aetna plan types — check the member's plan before scheduling.
The real issue here is that with 640-plus CPT codes in scope, your billing team can't treat this as a quick audit. Medical necessity documentation must align with whatever selection criteria Aetna has established for each specific indication. A missing operative note detail or absent clinical rationale is enough to trigger a denial on a high-dollar graft procedure. If you're not sure how your specific payer mix maps to these criteria, loop in your compliance officer before the September 26, 2025 effective date passes without a review.
Aetna Bone and Tendon Graft Substitutes Exclusions and Non-Covered Indications
The not-covered group in CPB 0411 is long and specific. Aetna has drawn a clear line on several categories of graft-related procedures — calling them out explicitly means your billing team should treat these as hard denials, not appeal targets.
The following codes are not covered for the indications listed in CPB 0411. Billing these to Aetna without a covered alternate indication is a waste of claim submission and appeal resources.
PRP and biologic injections — CPT 0232T (platelet-rich plasma injection, any tissue, including image guidance, harvesting and preparation) and CPT 0481T (autologous white blood cell concentrate/autologous protein solution injection, any site) are both explicitly not covered. PRP billing has been a frequent denial target across payers, and Aetna's position here is consistent with that broader trend.
Emerging cellular and disc therapies — CPT codes 0627T, 0628T, 0629T, and 0630T cover percutaneous injection of allogeneic cellular and/or tissue-based products into the intervertebral disc (unilateral and bilateral approaches). All four are not covered. If your spine practice has been billing these, stop and review your Aetna claims now.
Knee and joint cellular implants — CPT 0565T (autologous cellular implant from adipose tissue for osteoarthritis of the knee) and CPT 0566T (injection of cellular implant into knee joint including ultrasound guidance, unilateral) are both not covered. The same applies to CPT 0737T (xenograft implantation into the articular surface).
Bone quality testing — CPT 0547T (bone-material quality testing by microindentation of the tibia, with results reported as a score) is not covered under this policy. This one catches practices that bill diagnostic adjuncts alongside graft procedures.
Other non-covered codes — CPT 0869T (injection of bone-substitute material for bone and/or soft tissue hardware fixation augmentation), CPT 0841T (digitization of glass microscope slides for pathology consultation during surgery), CPT 38232 (bone marrow harvesting for transplantation, autologous), CPT 38240 and 38241 (hematopoietic progenitor cell transplantation), and CPT 46707 (repair of anorectal fistula with plug, e.g., porcine small intestine submucosa) are all explicitly not covered for the indications in CPB 0411.
This list should go directly into your charge capture review. Any of these codes hitting an Aetna claim after September 26, 2025 without a covered indication will deny.

Aetna Bone Graft Substitute Billing Guidelines and Action Items 2025
| # | Action Item |
|---|---|
| 1 | Pull every Aetna claim from the past 90 days that includes any CPT code in the 0707T, 11981–11983, 20700–20702, 20930–20931, 0232T, 0481T, 0547T, 0565T–0566T, 0627T–0630T, 0737T, 0841T, or 0869T range. Flag any that hit the "not covered" group. If those claims are still within your appeal window, review them before writing off the balance. |
| 2 | Update your charge capture system to flag CPT 0232T, 0481T, 0565T, 0566T, 0627T, 0628T, 0629T, 0630T, 0737T, and 0869T as non-covered under Aetna CPB 0411. These codes should trigger a warning or block when the payer is Aetna. Do this before submitting any claims with dates of service on or after September 26, 2025. |
| 3 | Verify prior authorization requirements for calcium sulfate antibiotic bead procedures (CPT 0707T, 11981, 11982, 11983, +20700, +20701, +20702) at the plan level. The policy covers these when selection criteria are met, but plan-level prior auth requirements vary. A covered code without prior auth still denies. |
| 4 | Document medical necessity explicitly for CPT 20930 and 20931. These spinal allograft codes are covered — but only when selection criteria are met. Your operative report and pre-op documentation must state why morselized or structural allograft was medically necessary. Vague documentation on high-dollar spine cases is the fastest path to a claim denial. |
| 5 | Review your bone graft substitute billing with your compliance officer if your practice uses multiple codes from the "related codes" group (CPT 12001–12057 simple and intermediate repairs, CPT 20615, CPT 20900 and related bone graft codes). These aren't automatically covered or denied — their status depends on the primary procedure and indication. This is exactly the kind of ambiguity that leads to billing errors at scale. |
| 6 | Train your front-end staff on ABN (Advance Beneficiary Notice) equivalents for Aetna plans. For non-covered codes like PRP (CPT 0232T) and cellular knee implants (CPT 0565T, 0566T), patients need to understand their financial responsibility before the procedure. Surprise billing complaints on denied graft claims are avoidable with the right pre-service conversation. |
