CPT 41830: Removal of Alveolar Process Including Inflamed or Dead Bone

CPT code 41830 denotes surgical removal of part of the alveolar process, including inflamed and necrotic bone. Nationally, this procedure is a focused oral and maxillofacial surgical service used to treat localized jawbone disease that compromises the alveolar ridge and tooth-supporting structures. It is relevant for surgical practices, dental specialists, and payers managing coverage for oral surgery procedures.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, typical sites of service, and the common payer landscape. The publication summarizes benchmark considerations, common billing modifiers (listed separately), and coding relationships when available.

This summary provides clinicians and billing professionals with the information needed to identify the procedure, understand where it is typically performed, and recognize the primary payers involved in national coverage discussions. Data not provided in the input—such as associated taxonomies, specific ICD-10 diagnosis codes, and related procedure codes—are indicated as unavailable and are not included here.

Billing Code Overview

CPT code 41830 describes a surgical procedure in which the provider removes a portion of the alveolar process, including inflamed and necrotic (dead) bone. This procedure addresses localized disease of the jawbone associated with the tooth-supporting alveolar ridge.

Service type: Surgical debridement/removal of alveolar bone
Typical site of service: Oral and maxillofacial surgery setting, commonly performed in an ambulatory surgical center, hospital outpatient department, or dental/oral surgery clinic

Clinical & Coding Specifications

Clinical Context

A 58-year-old patient presents with chronic mandibular pain, persistent gingival swelling, and a non-healing extraction site after prior tooth removal. Imaging (panoramic radiograph or CT) demonstrates sequestrum and areas of necrotic alveolar bone consistent with alveolitis/osteonecrosis. After failed conservative management including antibiotics and local debridement, the oral and maxillofacial surgeon schedules a surgical procedure to remove the infected and nonviable portion of the alveolar process. The patient arrives to the ambulatory surgery center (or hospital outpatient department for complex cases) after standard preoperative assessment, including medical history, medication reconciliation (notably anticoagulants or bisphosphonate exposure), and informed consent. Under local anesthesia with conscious sedation or general anesthesia when indicated, the surgeon elevates full-thickness mucoperiosteal flaps, identifies and removes inflamed and dead bone (sequestrectomy and alveoloplasty as needed), achieves hemostasis, irrigates the site, and closes the wound. Postoperative instructions include analgesia, antibiotics if indicated, and scheduled follow-up for wound inspection and potential staged reconstruction or prosthetic planning. Typical sites of service are the ambulatory surgery center or hospital outpatient department; the service type is surgical—oral/maxillofacial surgical debridement of alveolar process.

Coding Specifications

Modifier	Description	When to Use
`22`	Increased procedural service	Use when work required is substantially greater than typically required (extensive debridement, unusually difficult dissection).
`23`	Unusual anesthesia	Use when the procedure is performed under general anesthesia in a case typically performed under local anesthesia due to extenuating circumstances.
`50`	Bilateral procedure	Use for procedures performed bilaterally in the same operative session (both sides of the mandible/maxilla).
`51`	Multiple procedures	Use when multiple distinct procedures are performed at the same operative session in addition to `41830`.
`52`	Reduced services	Use when the procedure is partially reduced or not completed as planned.
`53`	Discontinued procedure	Use when the procedure is started but halted due to unforeseen circumstances.
`62`	Two surgeons	Use when two surgeons of different specialties work together as primary surgeons due to complexity.
`78`	Unplanned return to the operating room	Use when the patient returns to the OR for a related procedure during the global period.
`80`	Assistant surgeon	Use when a surgical assistant is required and documented.
`81`	Minimum assistant surgeon	Use when a minimal assistant is documented and meets payer requirements.
`82`	Assistant surgeon (when qualified resident unavailable)	Use when a qualified resident is not available and an assistant surgeon is used.
`LT`	Left side	Use to indicate procedure performed on the left side when laterality is reportable.
`RT`	Right side	Use to indicate procedure performed on the right side when laterality is reportable.
`TC`	Technical component	Use when billing only the technical component (applies mainly to diagnostic services; included here for completeness when combined services are split).
