Cigna modified MM 0586 covering alveoloplasty, effective December 2, 2025. Here's what billing teams need to do.
Cigna Healthcare updated its coverage policy for alveoloplasty under policy code MM 0586. This policy governs CPT 41874 — alveoloplasty, each quadrant — a surgical procedure for recontouring supporting alveolar bone, often performed in preparation for a prosthesis. If your practice or facility bills 41874 to Cigna, this update affects your medical necessity documentation and claim submission process starting December 2, 2025.

Cigna Alveoloplasty Coverage Criteria and Medical Necessity Requirements 2025
The Cigna alveoloplasty coverage policy under MM 0586 addresses a specific surgical context. Alveoloplasty — also spelled alveoplasty — involves surgically recontouring the alveolar bone that supports the teeth. Surgeons perform this procedure to smooth, reshape, or reduce bone in preparation for a prosthesis, or when residual bone irregularities require correction after tooth extraction.
CPT 41874 is billed per quadrant. That billing structure matters because it directly affects reimbursement — a patient with multi-quadrant involvement generates multiple line items on a single claim. Each quadrant must meet medical necessity on its own. Billing four quadrants without quadrant-level documentation is a direct path to claim denial.
Under MM 0586, Cigna considers CPT 41874 medically necessary when the applicable selection criteria are met. The policy does not list blanket approval. Medical necessity is the controlling factor for coverage, and that determination is made at the claim level based on your submitted documentation.
The policy is clear on one thing: alveoloplasty is a covered service when criteria are met. That means your operative note, procedure report, and diagnosis coding need to tell a coherent story about why the recontouring was clinically required.
As general RCM best practice — not a requirement stated in MM 0586 — verify prior authorization requirements before scheduling. Cigna's medical and dental plan structures can differ significantly. Some Cigna commercial plans route oral surgery procedures through a separate dental benefit. If alveoloplasty is being billed under the medical benefit using CPT 41874, confirm that the patient's plan covers surgical oral procedures under that benefit. When in doubt, loop in your billing consultant or compliance officer before the effective date of any new Cigna plan year.
The real issue with this kind of policy update is the documentation gap. Surgeons often perform alveoloplasty as part of a larger extraction or pre-prosthetic surgery case. When it is bundled into a broader procedure, the alveoloplasty-specific necessity sometimes doesn't get its own documentation. That's a problem when Cigna audits the claim. Write it out separately in the operative note.

Cigna Alveoloplasty Billing Guidelines and Action Items 2025
The following action items apply to any practice or facility billing CPT 41874 to Cigna on or after December 2, 2025.
| # | Action Item |
|---|---|
| 1 | Audit your active Cigna claims for CPT 41874. Pull any claims submitted on or after December 2, 2025. Confirm they include quadrant-specific documentation. A claim that says "alveoloplasty performed" without specifying which quadrant and why fails the per-quadrant billing requirement baked into CPT 41874's descriptor. |
| 2 | Update your charge capture templates. If your EHR or billing software uses a charge capture shortcut for 41874, add a documentation prompt requiring the treating surgeon to specify the quadrant and the clinical indication — bone recontouring for prosthesis preparation, residual ridge irregularity, or other documented necessity. Do this before December 2, 2025. |
| 3 | Confirm benefit structure before billing. For each Cigna patient scheduled for alveoloplasty, verify whether the procedure is covered under the medical or dental benefit. CPT 41874 is a medical code. If the patient's Cigna plan routes oral surgery through the dental benefit, confirm which code set and billing channel that plan requires before submitting. Billing the wrong benefit is a common and avoidable denial. |
| 4 | Check prior authorization requirements by plan. As a general RCM best practice — not a requirement stated in MM 0586 — run a benefits and authorization check for each patient. Cigna's prior authorization requirements vary by commercial plan and employer group. If prior authorization is required and you don't get it, the claim denial will be clean. |
| 5 | Train your surgical documentation team. Alveoplasty billing fails most often at the documentation level, not the coding level. Make sure the surgeon's operative note for CPT 41874 includes the specific quadrant(s) treated, the clinical reason for bone recontouring, the relationship to prosthesis preparation if applicable, and the technique used. Vague notes produce denials. This applies to all Cigna alveoloplasty billing under MM 0586 going forward. |
| 6 | Watch for claim denials tied to this update. Cigna modified MM 0586 — the source data confirms this but does not specify what changed. Expect a possible short-term uptick in denials as their claims processing aligns to the updated version. Pull denial reports for CPT 41874 in the 60 days following December 2, 2025. If you see a pattern, call your Cigna provider rep for clarification on the current criteria. |

CPT, HCPCS, and ICD-10 Codes for Alveoloplasty Under MM 0586
The policy data for MM 0586 includes one CPT code. No HCPCS or ICD-10 codes are listed in the policy document.
Covered CPT Codes (When Medical Necessity Criteria Are Met)
| Code | Type | Description |
|---|---|---|
| 41874 | CPT | Alveoloplasty, each quadrant (specify) |
A note on CPT 41874 billing: The "(specify)" in the descriptor is not decorative. It is a direct instruction to identify the quadrant on the claim. Use standard quadrant modifiers or document the quadrant in the claim narrative as your payer requires. Missing this detail is a denial waiting to happen.
No not-covered or experimental codes are listed in the MM 0586 policy data. No ICD-10-CM diagnosis codes are listed in this policy. You will need to select appropriate diagnosis codes based on the clinical scenario. Talk to your coding team about which ICD-10 codes best support the medical necessity narrative for each case.
