Official Description

Incision and drainage below fascia, with or without tendon sheath involvement, foot; multiple areas

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 28003 involves an incision and drainage operation performed below the fascia of the foot, specifically targeting multiple areas that may be affected by infection. This procedure is typically indicated when there is an accumulation of pus or fluid in the bursal spaces, which can lead to significant discomfort and potential complications if not addressed. During the operation, a surgical incision is made through the skin to access the underlying soft tissues. The surgeon carefully dissects these tissues to expose the fascia, which is a connective tissue layer that covers muscles and organs. Once the fascia is incised, the tendon sheath may also be inspected to assess any involvement in the infection. The infected bursal space is then opened using a scalpel, allowing for the drainage of the accumulated fluid. To ensure thorough cleaning of the area, the site is often flushed with saline or an antibiotic solution, which helps to reduce the risk of further infection. Depending on the extent of the drainage and the surgeon's assessment, drains may be placed to facilitate ongoing fluid removal. After the procedure, the incision may be closed in layers to promote healing or packed with gauze and left open to allow for continued drainage. It is important to note that this code is specifically used for cases involving multiple bursal spaces, while CPT® Code 28002 is designated for procedures involving a single bursal space.

1. Indications

The procedure associated with CPT® Code 28003 is indicated for the following conditions:

  • Infected Bursa The presence of an infected bursa in the foot, which may lead to pain, swelling, and limited mobility.
  • Abscess Formation The formation of an abscess in multiple areas of the foot, requiring surgical intervention for drainage.
  • Fluid Accumulation Accumulation of pus or other fluids in the bursal spaces that necessitates drainage to alleviate symptoms and prevent complications.

2. Procedure

The procedure for CPT® Code 28003 involves several critical steps to ensure effective incision and drainage of multiple areas in the foot:

  • Step 1: Preparation The patient is positioned appropriately, and the surgical site is cleaned and sterilized to minimize the risk of infection. Local anesthesia may be administered to ensure the patient’s comfort during the procedure.
  • Step 2: Incision A surgical incision is made through the skin over the infected bursa. The incision is typically made in a location that allows for optimal access to the affected areas.
  • Step 3: Dissection The surgeon carefully dissects the soft tissues to expose the fascia, which is the connective tissue layer beneath the skin. This step is crucial for accessing the underlying structures.
  • Step 4: Fascia Incision Once the fascia is exposed, it is incised to allow access to the tendon sheath and the infected bursal space. This step may involve careful manipulation to avoid damaging surrounding tissues.
  • Step 5: Drainage The infected bursal space is opened with a scalpel, allowing for the drainage of pus or fluid. This is a critical step in alleviating the infection and associated symptoms.
  • Step 6: Flushing After drainage, the site is flushed with saline or an antibiotic solution to cleanse the area and reduce the risk of further infection.
  • Step 7: Drain Placement If necessary, drains may be placed in the incision site to facilitate ongoing drainage of any remaining fluid and to promote healing.
  • Step 8: Closure The incision may be closed in layers to promote proper healing, or it may be packed with gauze and left open, depending on the surgeon's assessment and the extent of the drainage required.

3. Post-Procedure

After the procedure, the patient may require monitoring for signs of infection or complications. Instructions for care at the incision site will be provided, which may include keeping the area clean and dry, changing dressings as needed, and observing for any unusual symptoms such as increased redness, swelling, or discharge. Follow-up appointments may be scheduled to assess healing and to remove any drains if placed. The expected recovery time can vary based on the extent of the procedure and the patient's overall health.

LT Left side (used to identify procedures performed on the left side of the body)
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.
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.)
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
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.
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).
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.)
GC This service has been performed in part by a resident under the direction of a teaching physician
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.
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
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.
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).
