Specialty Billing Built for Cardiac Electrophysiology

Device interrogation codes are selected by two dimensions: device type (pacemaker vs ICD) and modality (remote vs in-person). 93285 is pacemaker remote interrogation, 93286 is ICD remote, 93289 is pacemaker in-person evaluation, 93290 is ICD in-person evaluation, and 93291/93292 are in-person pulse-generator analysis with programming for pacemaker and ICD respectively. Only one interrogation code is billed per session — the correct code depends on the device the patient has and whether the evaluation was remote or in-person. We use a device-type and modality matrix so the single correct 93285-93292 code is selected every time, preventing the common downcoding of in-person programming to the lower-paying remote code.

Yes. A diagnostic EP study (93600 for the bundle-of-His evaluation, or 93615-93619 for inducibility and programmed stimulation) performed in the same session as an ablation is separately reportable because it is a distinct diagnostic service from the therapeutic ablation. It must be billed with modifier 59 (distinct procedural service) to break the NCCI bundling edit that otherwise bundles the diagnostic study into the ablation. Without modifier 59, the diagnostic EP study is denied as bundled. We verify the edit pair and append modifier 59 so the same-session diagnostic EP study is paid rather than denied.

Pacemaker and ICD implant codes (33206-33249) cover the generator pocket, the leads, and the system connection in specific combinations defined by NCCI edits. Single-chamber pacemaker insertion is 33206, dual-chamber 33207, and biventricular/CRT-P 33208; ICD insertion is 33249. Lead placement, generator replacement (33212-33213), and lead revision (33215-33244) are distinct codes that must be sequenced correctly against the primary implant code or they are denied as bundled. We verify the NCCI edit pairs and sequence the implant, lead, and generator codes so each legitimately separate component is paid — and we add assistant-surgeon modifier 80 where a qualified assistant participates in lead extraction or complex implant work.

EP studies and some device evaluation codes have a professional component (interpretation and programming analysis, modifier 26) and a technical component (equipment, testing, and technical staff, modifier TC). When a physician interprets a study performed by a technician or outside facility, only the 26 is billed. When the practice owns the equipment and performs the test, the TC or global component is billed per payer rules — Medicare requires the components split when a facility is involved. We apply the correct 26/TC split per payer on every EP study and device evaluation so neither the technical nor professional revenue is lost to a global-only denial.

Remote device interrogation (93285 for pacemaker, 93286 for ICD) covers monitoring and interrogation of a device from a remote location, typically with a scheduled transmission and physician review. In-person device evaluation (93289 for pacemaker, 93290 for ICD) covers a face-to-face evaluation including device interrogation, and 93291/93292 cover in-person pulse-generator analysis with programming. The two tracks are not interchangeable — a remote check cannot be billed as an in-person evaluation and vice versa — and the reimbursement differs substantially. We confirm the modality performed and the device type, then select the single matching code from 93285-93292 so remote and in-person device checks are paid at the correct rate.
