Headline: CPT code 0164T defines an add-on surgical procedure for removal of an additional lumbar artificial disc during the same operative session as primary lumbar total disc arthroplasty.

Lead: CPT code 0164T captures a specific intraoperative action — removal of another artificial lumbar disc at a separate interspace during the same surgery — and is relevant for surgical billing, hospital coding workflows, and payer adjudication for spine arthroplasty cases.

What the code represents and why it matters: CPT code 0164T documents an add-on spinal surgical service that occurs in the context of lumbar total disc arthroplasty. Accurate use of this add-on code affects clinical documentation, operative reporting, and claims submission for multi-level disc procedures. Given the complexity and cost of spinal implant procedures, correct coding has implications for provider reimbursement and claims processing across major payers.

Key payers covered: The analysis addresses national coverage and billing practices for Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Overview of what readers will learn: Readers will find clinical context for when 0164T applies, typical sites of service, common billing modifiers and claims considerations, and how major payers approach adjudication and coverage nuances. The publication also summarizes benchmarking and policy considerations relevant to multi-level lumbar disc arthroplasty.
