CPT code 23333 designates the surgical removal of a foreign body from the shoulder’s subfascial or intramuscular tissue. This procedure-level code captures interventions to extract nonnative material embedded beneath the fascial plane or within shoulder musculature, a clinically important service for preventing infection, persistent pain, and impaired function. Nationally, accurate coding for such procedures affects provider reimbursement, quality measurement, and claims adjudication for shoulder surgery.

Readers will find a concise overview of coding intent, typical sites of service (ambulatory surgical centers and hospital operating rooms), and clinical context for when the code applies. The analysis includes benchmarking and policy implications where available, as well as operational considerations for documentation and claim submission. Data not available in the input will be noted where applicable.

This publication provides clinicians, coding professionals, and policy analysts with clear guidance on the purpose of CPT code 23333, what clinical scenarios it represents, and where it fits in surgical service lines and billing workflows.
