A skin abscess is a pocket of pus that forms under the skin. Incision and drainage (I&D) is the key treatment for skin and soft tissue abscesses. This minor surgical procedure involves making an incision in the skin over the abscess to allow for drainage of the pus or pressure. Thorough documentation is crucial for accurate coding and reimbursement of abscess treatments. Comprehensive documentation supports the medical necessity of the incision and drainage procedure, and provides a full description of the services rendered. By meticulously reviewing clinical notes to capture all necessary details, a medical coding company can ensure accurate code assignment for abscess incision and drainage (I&D) procedures.
Ensure accurate CPT and ICD-10 code selection for I&D procedures and maximize reimbursement!
Simple versus Complicated I&D
The complexity of the I&D procedure is a key factor for accurate code assignment. “One of the most common errors is selecting the wrong CPT code based on the complexity of the procedure. Simple procedures should not be coded as complicated ones and vice versa,” notes an AAPC article.
The documentation should clearly indicate if the procedure was simple or complex. The complexity of the procedure is determined by the provider. In general, I&Ds are considered complicated if they involve wound packing, drain insertion, and/or probing and deloculation. Additionally, when multiple skin or subcutaneous I&Ds are performed during the same encounter, CPT guidelines require coding them as a single complicated procedure rather than reporting multiple simple I&Ds.
Thorough Documentation is Key for Accurate Coding
The CPT/ICD-10 codes for incision and drainage (I&D) procedures depend on various factors. In addition to relevant medical history, physical examination, and results of pertinent diagnostic tests or procedures, the American College of Emergency Physicians (ACEP) states that, to determine the appropriate codes, the documentation should specify the following:
- The location of the lesion
- The lesion’s depth, and type
- The presence of complicating conditions
- Multiple lesions
- Whether the procedure was simple or complex
- Signs and symptoms that justified the I&D procedure
- Detailed wound characteristics, such as pre-procedure size, exact location, and lesion type (e.g., abscess, paronychia, hidradenitis suppurativa, furuncle, carbuncle, lymphangitis, hematoma, or cyst).
- The method of incision or puncture, the amount and quality of drainage, any probing and deloculation performed.
The medical record documentation should also indicate whether the wound was packed, a drain was inserted, a vessel loop was placed, or the wound was left open.

ICD-10 Codes
Claims should be submitted with valid ICD-10 diagnosis code(s) that support medical necessity. The diagnosis code(s) must best describe the patient’s condition for which the service was performed. Here are some examples of ICD-10 codes for I&D services:
- J34.0 Abscess, furuncle and carbuncle of nose
- K12.2 Cellulitis and abscess of mouth
- K61.31 Horseshoe abscess
- K61.39 Other ischiorectal abscess
- K61.5 Supralevator abscess
- K68.11 Postprocedural retroperitoneal abscess
- L02.01 Cutaneous abscess of face
- L02.11 Cutaneous abscess of neck
- L02.211 Cutaneous abscess of abdominal wall
- L02.212 Cutaneous abscess of back [any part, except buttock]
- L02.213 Cutaneous abscess of chest wall
- L02.214 Cutaneous abscess of groin
- L02.215 Cutaneous abscess of perineum
L02.216 Cutaneous abscess of umbilicus - L02.31 Cutaneous abscess of buttock
- L02.411 Cutaneous abscess of right axilla
- L02.412 Cutaneous abscess of left axilla
- L02.413 Cutaneous abscess of right upper limb
- L02.414 Cutaneous abscess of left upper limb

Reporting Diagnostic Tests
- For diagnostic tests, report either the test results (if known) or the symptoms that justified performing the test.
- Ultrasound interpretation is a separately billable service used to diagnose and locate cysts, hematomas, seromas, or abscesses. Specific ultrasound codes exist for:
- Soft tissues of the head and neck
- Non-vascular extremity structures
- Body areas such as the abdomen, chest/upper back (CPT 76604), and scrotum contents
- To bill for ultrasound services:
-
- Permanent image retention is required.
- Documented findings must support the medical necessity of the study.
- Use the -26 modifier to indicate professional component interpretation.
Complying with Local Coverage Determination (LCD) Requirements
Procedure codes may be impacted by NCCI or OPPS packaging edits, which impact Medicare billing. CMS advises reviewing NCCI and LCD guidelines to ensure compliance. The medical record must clearly document the medical necessity of services covered under the LCD.
The guidance further states that providers who frequently bill for repeated I&D of the same area may need to submit additional documentation, such as photographs, operative reports, or progress notes. When a patient undergoes multiple I&D procedures for an abscess in the same location, the medical record must clearly explain the medical necessity of repeated treatment, including the reasons for persistent or recurrent infection and the preventive measures taken
Coding Expertise Matters
When performed safely and effectively, incision and drainage (I&D) procedures provide significant relief from abscess-related symptoms. Accurate documentation is essential to distinguish between simple and complicated I&D procedures. It should include all relevant details, such as the size and location of the abscess (es), the type of incision(s), and any complications encountered during the procedure.
Partnering with professional medical billing and coding services is a practical way to ensure accurate claim submission for I&D procedures. Experts with in-depth knowledge of CPT and ICD codes can minimize coding errors and optimize reimbursement. They carefully review clinical notes to capture all necessary details for precise coding and stay updated on changes to CPT codes and guidelines to maintain compliance with current standards.
