Clinical Context
A 66-year-old patient with treatment-resistant, symptomatic hypertension and/or heart failure refractory to optimal medical therapy is evaluated for implantation of a Baroreflex Activation Therapy (BAT) system. After multidisciplinary assessment including cardiology, electrophysiology, vascular surgery, and anesthesia clearance, the patient is scheduled for an implant procedure. In the operating room or hybrid suite under monitored anesthesia care or general anesthesia, the provider exposes the carotid sinus region in the neck, secures a programmable stimulation lead to the carotid sinus, tunnels the lead subcutaneously to a separate pocket site (commonly subclavicular), connects the lead to an implanted pulse generator, closes all incisions, and performs intraoperative device interrogation and programming. Postoperative workflow includes short-term monitoring for hemodynamic stability, wound care instructions, device programming optimization in follow-up clinic, and coordination of outpatient cardiology and device clinic visits for ongoing therapy management.
Coding Specifications
| Modifier | Description | When to Use |
|---|
24 | Unrelated Evaluation and Management service by the same physician during a postoperative period | Use if an unrelated E/M is provided unrelated to the BAT implant during the global period |
25 | Significant, separately identifiable E/M service by the same physician on the day of a procedure | Use when a significant E/M is performed the same day as 64654 that is separate from the implant
50 | Bilateral procedure | Use if the procedure requires bilateral carotid sinus lead placement and payer allows bilateral reporting
59 | Distinct procedural service | Use when a distinct non-overlapping service is performed the same day that is not usually billed together with 64654
76 | Repeat procedure by same physician | Use when the same BAT implantation procedure is repeated by the same physician during the same postoperative period
77 | Repeat procedure by another physician | Use when another physician repeats the procedure during the same postoperative period
78 | Unplanned return to the operating room for a related procedure during the postoperative period | Use for a return to OR for complications related to the BAT implant
79 | Unrelated procedure or service during the postoperative period by the same physician | Use when an unrelated procedure is performed during the global period
PP | Personal pronoun not a CMS modifier; Data not available in the input. | Data not available in the input.
