Summary & Overview
CPT 23930: Incision and Drainage of Deep Upper Arm/Elbow Abscess
CPT code 23930 represents a surgical incision and drainage procedure targeting abscesses or collected clotted blood within the deep soft tissues of the upper arm or elbow. This procedure is clinically important because timely drainage of deep infections or hematomas reduces complications such as spread of infection, tissue necrosis, prolonged hospitalization, and the need for more extensive surgery. Nationally, this code captures an acute, procedure-driven episode of care that intersects emergency, inpatient, and ambulatory surgical settings.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for the procedure, common sites of service, and the types of benchmarks typically examined for this code, including utilization patterns, place-of-service distribution, and expected clinical indications. The publication also summarizes recent policy or coverage considerations affecting procedural coding and billing for incision and drainage of deep upper-arm or elbow collections.
This resource is intended to inform payers, hospital billing teams, and clinician coders about the clinical scope of CPT code 23930, what the code denotes in practice, and the higher-level topics to review when assessing coverage, payment, and coding compliance for deep soft-tissue drainage procedures.
Billing Code Overview
CPT code 23930 describes an incision and drainage procedure for an abscess or hematoma located in the deep structures of the upper arm or elbow. The procedure involves making an incision to evacuate pus, clot, or other infected or collected material from deep soft tissues.
-
Service type: Surgical incision and drainage of deep upper arm/elbow soft-tissue collections
-
Typical site of service: Ambulatory surgical center, hospital operating room, or emergency department depending on clinical acuity and available resources

Clinical & Coding Specifications
Clinical Context
A 46-year-old male presents to the emergency department with acute progressive swelling, severe pain, erythema, and fluctuance over the medial aspect of the upper arm following blunt trauma sustained two days earlier. The patient is febrile and has limited elbow range of motion. Point-of-care ultrasound demonstrates a localized fluid collection deep to the subcutaneous tissue adjacent to the brachial muscle and near the elbow joint, suspicious for a deep soft-tissue abscess or organized hematoma. The attending orthopedic or general surgery provider obtains informed consent and performs a procedural incision and drainage under local anesthesia with exploration of the deep tissues to evacuate purulent material and clotted blood. Specimens are sent for gram stain and culture; the wound is irrigated, hemostasis achieved, and either left open with packing or a drain placed depending on the depth and contamination. Post-procedure documentation includes the extent of deep dissection, estimated volume of drainage, anesthesia used, complications (if any), and follow-up wound care instructions.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
11 | Provider’s default procedural service | Use when this is the routine, uncomplicated incision and drainage performed by the reporting surgeon. |
22 | Increased procedural services | Use when documentation supports substantially greater work (extensive deep dissection, multiple loculations, prolonged operative time) than typical for 23930. |
23 | Unusual anesthesia | Use when the procedure required anesthesia that is beyond local (e.g., sedation or general) and documentation supports unusual anesthesia for a minor procedure. |
52 | Reduced services | Use when only partial procedure was performed (limited exploration or aborted due to patient instability). |
53 | Discontinued procedure | Use when the procedure was started but terminated for patient-related reasons before completion. |
59 | Distinct procedural service | Use when another non-overlapping procedure is performed on the same limb or same day and is unrelated to the incision and drainage. |
62 | Two surgeons | Use when two surgeons from different specialties actively work together as primary surgeons for a complex deep I&D. |
76 / 77 not listed but related — excluded per input | Data not available in the input. | |
LT | Left side | Use to indicate the procedure was performed on the left upper arm/elbow. |
RT | Right side | Use to indicate the procedure was performed on the right upper arm/elbow. |
50 | Bilateral procedure | Use when identical procedures are performed bilaterally (rare for arms) — apply only if both upper arms required I&D. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
| 207K00000X | Orthopaedic Surgery | Orthopedists commonly manage deep upper-arm/elbow infections and hematomas requiring deep I&D. |
| 2080P0200X | General Surgery | General surgeons perform incision and drainage of deep soft-tissue collections in emergency or OR settings. |
| 208000000X | Emergency Medicine | Emergency physicians frequently perform initial I&Ds in the ED for acute deep abscesses; may consult surgery. |
| 363A00000X | Plastic Surgery | Plastic surgeons may perform complex deep soft-tissue debridement and closure planning for contaminated wounds. |
