Summary & Overview
CPT 24200: Subcutaneous Foreign Body Removal to Fascia
CPT code 24200 denotes surgical removal of a subcutaneous foreign body with incision carried to the level of fascia. This procedure is used when a foreign object lodged beneath the skin requires operative extraction that extends to, but does not penetrate, the fascial layer. Nationally, proper coding of this service affects claims processing, site-of-service designation, and expected cost-sharing for patients who present with embedded foreign bodies.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines payer coverage considerations, typical allowed service settings, and common billing practices related to minor outpatient surgical removal of foreign bodies.
Readers will learn the clinical context for using CPT code 24200, where the procedure is commonly performed (outpatient clinic, ambulatory surgery center, emergency department), and which elements of documentation support correct reporting. The summary highlights expected policy topics such as definitions of subcutaneous versus deeper removals, distinctions from procedures that involve tendon or joint structures, and how service location can influence reimbursement. Data not available in the input is noted where applicable, and the report does not recommend clinical actions but provides an operational overview useful for coding, billing, and compliance staff.
Billing Code Overview
CPT code 24200 describes an incision and removal of a subcutaneous foreign body down to the level of fascia. The procedure involves making an incision through the subcutaneous layer of the skin to extract a foreign object that lies beneath the skin but superficial to the underlying muscle fascia.
Service type: Minor surgical procedure — foreign body removal, subcutaneous, to fascia
Typical site of service: Outpatient clinic, ambulatory surgery center, or emergency department
Clinical & Coding Specifications
Clinical Context
A typical patient is a 28-year-old construction worker who presents to an urgent care clinic after sustaining a puncture wound to the forearm from a metal fragment. The patient reports localized pain, mild erythema, and inability to palpate the foreign object beneath the skin. Physical exam demonstrates a small puncture with a palpable subcutaneous foreign body near the antecubital region without signs of deep structural injury. Plain radiographs confirm a radiopaque fragment superficial to the fascia. The provider discusses that removal in a procedure room under local anesthesia is appropriate.
The clinical workflow includes triage and wound assessment, informed consent, time-out, sterile prep and local anesthesia (e.g., lidocaine), a small incision through the subcutaneous tissue, blunt and sharp dissection down to the level of the fascia to locate and remove the foreign body, irrigation, hemostasis, and wound closure. Post-procedure instructions address tetanus status, wound care, signs of infection, and documentation of the removed object. If the foreign body is deeper than fascia or involves tendon/nerve/vessel injury, escalation to the operating room and different coding would be required.
