CPT code 23430 denotes surgical tenodesis of the long head of the biceps tendon, a procedure that removes a damaged tendon fragment and secures the tendon to the proximal humerus to restore shoulder stability and function. This code is nationally relevant because biceps tendon pathology and related shoulder dysfunction are common contributors to pain, loss of function, and surgical demand among adults; accurate coding affects clinical documentation, surgical quality reporting, and reimbursement consistency. Key payers discussed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn clinical context for use of the code, typical sites of service, and common modifiers associated with surgical procedures when available. The publication provides benchmarking and payment context where data exists, summarizes relevant policy updates impacting coverage or prior authorization practices, and outlines coding considerations that affect claim submission and medical record alignment. Data not available in the input is noted where applicable; the focus remains on national implications for providers, payers, and revenue cycle teams.
