Official Description

Incision and drainage, shoulder area; deep abscess or hematoma

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

An incision and drainage procedure for a deep abscess or hematoma in the shoulder area involves a surgical intervention aimed at alleviating the accumulation of pus or blood within the soft tissues surrounding the shoulder. The shoulder area encompasses the anatomical regions overlying the clavicle, scapula, and the humeral head and neck. The specific approach taken during the procedure is determined by the precise location of the abscess or hematoma. During the procedure, the surgeon dissects the soft tissues to locate the pocket of pus or blood. Once identified, the wall of the abscess or hematoma is incised to allow for the drainage of the accumulated fluid. In cases where a large abscess is present, additional probing may be necessary to break down loculations, ensuring that all infected material is effectively drained. Following the drainage, the site is typically flushed with an antibiotic solution and/or normal saline to reduce the risk of infection. Depending on the clinical situation, the abscess or hematoma site may be left open for continued drainage, packed with gauze to facilitate healing, or closed surgically. It is important to note that this procedure is distinct from the incision and drainage of an infected bursa, which is described under CPT® Code 23031, where the bursal sac is incised and the fluid is similarly drained and flushed.

1. Indications

The procedure of incision and drainage of a deep abscess or hematoma in the shoulder area is indicated for the following conditions:

  • Deep Abscess The presence of a localized collection of pus within the soft tissues of the shoulder, which may cause pain, swelling, and potential systemic infection.
  • Hematoma Accumulation of blood within the shoulder tissues, often resulting from trauma or injury, leading to swelling and discomfort.

2. Procedure

The procedure involves several critical steps to ensure effective drainage and management of the abscess or hematoma:

  • Step 1: Preparation The patient is positioned appropriately to allow access to the shoulder area. The skin over the surgical site is cleaned and sterilized to minimize the risk of infection.
  • Step 2: Incision A surgical incision is made over the area where the abscess or hematoma is located. The size and location of the incision are determined based on the depth and extent of the abscess or hematoma.
  • Step 3: Dissection The surgeon carefully dissects the soft tissues to reach the pocket of pus or blood. This step requires precision to avoid damaging surrounding structures.
  • Step 4: Drainage Once the abscess or hematoma is accessed, the wall is incised, allowing the pus or blood to drain out completely. In cases of large abscesses, probing may be performed to break down loculations and ensure thorough drainage.
  • Step 5: Flushing After drainage, the cavity is flushed with an antibiotic solution and/or normal saline to cleanse the area and reduce the risk of infection.
  • Step 6: Closure The site may be left open for continued drainage, packed with gauze to promote healing, or closed with sutures, depending on the clinical judgment of the surgeon.

3. Post-Procedure

Post-procedure care involves monitoring the surgical site for signs of infection, such as increased redness, swelling, or discharge. Patients may be advised on wound care, including how to keep the area clean and dry. Pain management may be necessary, and follow-up appointments should be scheduled to assess healing and determine if further intervention is required. If the site was left open, instructions on how to care for the packing and when to return for packing changes or closure will be provided.

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.
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.
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.
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).
