CPT code 23040 defines an open shoulder joint exploration performed to inspect the glenohumeral space, evacuate fluid, and remove debris after recurrent dislocation or traumatic injury. Nationally, this code captures a procedure that is both diagnostic and therapeutic, often used when less invasive measures are insufficient or when intra-articular pathology must be addressed directly.

Key payers examined in typical analyses include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. These payers commonly evaluate claims for medical necessity, documentation of prior conservative treatments, and operative reports supporting the indication for open exploration versus arthroscopic alternatives.

Readers will find clinical context describing when open shoulder exploration is used, expected settings of care (operating room or ambulatory surgical center), and the types of documentation payers review. The publication also covers benchmarks and payer policy patterns where available, and highlights policy updates and coding considerations relevant to surgical shoulder care. Data not available in the input will be identified as such in relevant sections.
