Summary & Overview
CPT 11730: Simple Avulsion of Single Nail Plate
CPT code 11730 denotes the simple avulsion of part or all of a single nail plate — a common minor surgical procedure performed for nail disorders such as ingrowing nails, onycholysis, and other dystrophies. Nationally, this code matters because it captures a frequently used office-based procedural service that affects coding accuracy, billing consistency, and outpatient utilization patterns across payers. Payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare.
Readers will find a concise clinical and coding overview, comparison of how major payers handle coverage and billing for simple nail avulsion, and context on related procedural options. The publication outlines benchmarks for typical sites of service (office, clinic, outpatient procedure rooms), highlights common clinical indications tied to this service, and explains adjacent codes that represent more extensive nail procedures. This resource is intended to aid coding professionals, revenue cycle staff, and policy analysts in understanding where 11730 fits in the procedural spectrum and what to consider when classifying nail procedures for national billing and reporting purposes.
Billing Code Overview
CPT code 11730 describes the simple avulsion (partial or complete) of a single nail plate. This procedure involves removal of part or all of a single fingernail or toenail using straightforward avulsion techniques.
Service type: Minor surgical procedure / nail avulsion
Typical site of service: Office, clinic, or outpatient procedural setting
Clinical & Coding Specifications
Clinical Context
A 28-year-old patient presents to a dermatology clinic with a painful, inflamed great toenail consistent with an ingrowing nail. After examination and brief history confirming episodic pain, local erythema, and failure of conservative measures (soaking and topical antibiotics), the clinician elects to perform a simple nail avulsion of the affected single nail plate under local anesthesia. The patient is placed in a seated position on a clinic procedure chair; the toe is prepped with antiseptic and a digital nerve block is performed when indicated. Using simple avulsion techniques, the provider loosens and removes part or all of the nail plate, controls bleeding with pressure and topical hemostatic measures, inspects the nail bed for retained debris or spicules, and applies a sterile dressing. Post-procedure instructions, wound care guidance, and follow-up are documented. Typical site of service is an outpatient dermatology clinic, pediatric dermatology clinic, podiatry clinic, or ambulatory surgical center for more complex cases. This procedure aligns with management of diagnoses such as L60.0 (ingrowing nail), L60.1 (onycholysis), L60.2 (onychogryphosis), L60.3 (nail dystrophy), and L60.4 (Beau's lines).
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
25 | Significant, separately identifiable evaluation and management service by the same physician on the same day of procedure | Use when a distinct E/M visit is documented the same day as the avulsion (e.g., evaluation preceding decision to avulse). |
52 | Reduced services | Use when a partially reduced avulsion is performed and full service description is not met. |
53 | Discontinued procedure | Use if the avulsion was started but terminated due to patient intolerance or unexpected complication. |
59 | Distinct procedural service | Use when the avulsion is billed with another procedure on the same digit and documentation supports distinct services. |
76 | Repeat procedure by same physician | Use if the same provider repeats the avulsion procedure on the same day. |
77 | Repeat procedure by another physician | Use if a different provider repeats the avulsion on the same day. |
50 | Bilateral procedure | Use when an identical avulsion is performed on both corresponding digits (if payer accepts for this CPT). |
51 | Multiple procedures | Use when other unrelated procedures are billed the same day and payer requires modifier for multiple procedures. |
22 | Increased procedural service | Use when the avulsion required substantially greater effort or operative time than typical and documentation supports increased work. |
59 | Distinct procedural service | (Listed intentionally once in policy tables; see above) |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207NP0225X | Pediatric Dermatology Physician | Pediatric specialists performing nail procedures on children; use when provider’s taxonomy matches. |
207NS0135X | Procedural Dermatology Physician | Procedural dermatologists who commonly perform nail avulsions in outpatient settings. |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
L60.0 | Ingrowing nail | Common indication for single nail plate avulsion to relieve pain and infection risk. |
L60.1 | Onycholysis | Nail plate separation that may necessitate partial or complete avulsion if symptomatic or interfering with treatment. |
L60.2 | Onychogryphosis | Thickened, deformed nail that may require avulsion for symptomatic relief or to allow definitive treatment. |
L60.3 | Nail dystrophy | Non-specific nail abnormalities where avulsion may be performed for diagnostic evaluation or symptomatic management. |
L60.4 | Beau's lines | Transverse depressions of the nail plate; avulsion may rarely be performed if nail pathology warrants direct inspection or treatment. |
Related CPT Codes
| CPT Code | Description | Relationship to This Procedure |
|---|---|---|
11732 | Add-on code for subsequent avulsion (additional nail) | Billed in addition to 11730 when more than one nail plate avulsed during the same session; used as an add-on. |
11750 | Excision of nail and nail matrix, partial or complete | Represents a deeper procedure removing the nail matrix; used when permanent removal or matricectomy is required beyond simple avulsion. |
11765 | Wedge resection (excision of nail fold) | Used when a portion of the nail fold must be excised (e.g., for recurrent ingrown nails) in addition to or instead of simple avulsion. |
