Summary & Overview
CPT 21030: Enucleation/Curettage of Benign Maxillary and Zygomatic Tumors
CPT code 21030 denotes enucleation and/or curettage for removal of benign tumors of the upper jaw (maxilla) and cheekbone (zygoma). This code captures a targeted maxillofacial surgical procedure and is relevant to surgical, dental-maxillofacial, and otolaryngology service lines. It matters nationally because it represents a discrete, often inpatient or ambulatory-surgical setting procedure that drives surgical resource use, anesthesia planning, and post-op care pathways for nonmalignant craniofacial tumors.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find clinical context for when enucleation and curettage are appropriate for benign maxillofacial lesions, typical sites of service, and the procedural scope captured by the code. The publication outlines benchmarks and payment context where available, common billing considerations, and potential policy updates that affect coverage and coding practice.
The report serves clinicians, billing professionals, and policy analysts seeking a concise reference on procedural definition, setting expectations for site-of-service, and the payer landscape nationally. Data not available in the input is noted where specific benchmarks, associated taxonomies, or ICD-10 mappings would normally be provided.
Billing Code Overview
CPT code 21030 describes surgical removal of benign tumors of the upper jaw (maxilla) and cheekbone (zygoma) by enucleation and/or curettage. Enucleation denotes removal of the tumor as a single intact mass; curettage denotes scraping out diseased tissue with a curette.
Service type: Surgical tumor excision of the maxillofacial region (enucleation and/or curettage)
Typical site of service: Hospital operating room or ambulatory surgical center; may also occur in outpatient surgical clinics with appropriate facilities for maxillofacial surgery
Clinical & Coding Specifications
Clinical Context
A 45-year-old patient presents to an oral and maxillofacial surgery clinic with a slowly enlarging, painless mass of the maxillary alveolus and adjacent maxillary sinus. Imaging (panoramic radiograph and maxillofacial CT) shows a well-circumscribed, noninvasive radiolucent lesion consistent with an odontogenic cyst or benign tumor confined to the maxilla and zygomatic buttress. After clinical evaluation and discussion of options, the provider schedules an operative removal under general anesthesia. In the operating room, the surgeon performs enucleation of the lesion with careful curettage of the surrounding bony cavity to remove residual pathological tissue. Hemostasis is obtained, and the site is irrigated and closed. The clinical workflow includes preoperative history and physical, informed consent, anesthesia documentation, intraoperative operative note (describing enucleation and curettage), and a pathology submission if tissue is sent. Typical postoperative care includes pain control, antibiotics if indicated, and outpatient follow-up for wound check and review of pathology results.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
00 | Default state; no modifier | Use when no other modifier applies and standard billing is appropriate |
11 | Primary service | Use when this procedure is the principal reason for the encounter |
22 | Increased procedural services | Use when work, time, or complexity substantially exceeds typical expectations for enucleation/curettage |
23 | Unusual anesthesia | Use when the procedure requires general anesthesia or other anesthesia unexpectedly due to patient condition |
26 | Professional component | Use when billing only the physician professional component separate from technical component (rare for this code) |
50 | Bilateral procedure | Use when identical enucleation/curettage procedures are performed bilaterally in the same session |
51 | Multiple procedures | Use when additional distinct procedures are performed during the same session alongside this procedure |
52 | Reduced services | Use when the procedure is partially reduced or not completed as originally planned |
53 | Discontinued procedure | Use when the procedure is started but discontinued due to extenuating circumstances |
59 | Distinct procedural service | Use to indicate a separate and distinct procedure or site when multiple procedures are billed that might be bundled |
62 | Two surgeons | Use when two surgeons work together as primary surgeons performing distinct portions of the procedure |
73 | Discontinued outpatient before anesthesia | Use when the outpatient procedure is cancelled prior to anesthesia administration |
78 | Unplanned return to OR | Use when the patient returns to the operating room for a related procedure during the postoperative global period |
80 | Assistant surgeon | Use when an assistant at surgery is billed for assisting the primary surgeon |
26 | Professional component | Use when only the physician interpretation or professional portion is billed (repeat of common relevant modifier) |

21050 | Excision, tumor, zygoma (cheekbone), radical | Used when the zygomatic bone requires formal resection rather than curettage |
