Official Description

Drainage of finger abscess; complicated (eg, felon)

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 26011 refers to the drainage of a complicated finger abscess, specifically in cases such as a felon. A felon is a type of abscess that occurs in the fingertip, affecting the area beneath the nail fold and the undersurface of the nail wall, known as the perionychium. This condition is more complex than a simple abscess due to its anatomical location and the potential for deeper infection. The procedure begins with the cleansing of the skin and the administration of a local anesthetic to ensure patient comfort. Following this, a straight or elliptical incision is made directly over the abscess to allow for effective drainage. The surgeon then uses blunt dissection to open any pockets of pus, facilitating the complete drainage of the abscess. After the pus is removed, the area is irrigated with a sterile solution to cleanse the wound and reduce the risk of further infection. It is important to differentiate this procedure from simpler drainage methods, as the complexity of a felon requires more careful handling and technique to ensure proper healing and recovery.

1. Indications

The procedure associated with CPT® Code 26011 is indicated for the drainage of complicated finger abscesses, particularly in cases where the abscess is classified as a felon. The following conditions may warrant this procedure:

  • Felon A felon is a painful infection that occurs in the fingertip, affecting the area beneath the nail fold and the undersurface of the nail wall, which can lead to significant complications if not treated properly.
  • Complicated Abscess Any finger abscess that presents with significant swelling, pain, or signs of deeper infection may require this more invasive drainage procedure to ensure complete resolution.

2. Procedure

The procedure for CPT® Code 26011 involves several critical steps to ensure effective drainage of the abscess. Each step is essential for the successful management of the condition:

  • Step 1: Skin Cleansing The first step involves thoroughly cleansing the skin over the affected area to minimize the risk of introducing bacteria during the procedure. This is typically done using an antiseptic solution.
  • Step 2: Anesthesia Administration A local anesthetic is then injected into the area surrounding the abscess. This step is crucial for ensuring that the patient remains comfortable and pain-free throughout the procedure.
  • Step 3: Incision Creation Following anesthesia, a straight or elliptical incision is made directly over the abscess. The choice of incision type may depend on the size and location of the abscess, as well as the surgeon's preference.
  • Step 4: Blunt Dissection The surgeon then uses blunt dissection techniques to carefully open any pockets of pus within the abscess. This step is vital for ensuring that all infected material is adequately drained.
  • Step 5: Abscess Drainage Once the pockets of pus are accessed, the abscess is drained completely. This step is critical to relieve pressure and pain associated with the infection.
  • Step 6: Irrigation After drainage, the area is irrigated with a sterile solution. This helps to cleanse the wound and remove any remaining debris or infectious material, promoting a cleaner healing environment.

3. Post-Procedure

Post-procedure care for a patient who has undergone drainage of a complicated finger abscess includes monitoring for signs of infection, such as increased redness, swelling, or discharge from the incision site. Patients are typically advised to keep the area clean and dry, and they may be instructed to change dressings as needed. Pain management may be necessary, and the use of over-the-counter analgesics can be recommended. Follow-up appointments may be scheduled to assess healing and ensure that the infection has resolved completely. It is important for patients to report any concerning symptoms to their healthcare provider promptly.

51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
LT Left side (used to identify procedures performed on the left side of the body)
RT Right side (used to identify procedures performed on the right side of the body)
22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
54 Surgical care only: when 1 physician or other qualified health care professional performs a surgical procedure and another provides preoperative and/or postoperative management, surgical services may be identified by adding modifier 54 to the usual procedure number.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
