Clinical Context
A typical patient is a 65-year-old man with localized, biopsy-proven prostate carcinoma confined to the gland who elects focal tumor ablation. He presents after multiparametric MRI and targeted biopsy confirm one or more discrete tumor foci suitable for a percutaneous approach. Pre-procedure assessment includes medical clearance, coagulation review, and review of prior imaging (MRI/ultrasound). On the day of service, the patient receives conscious sedation or general anesthesia in an outpatient procedural suite or ambulatory surgery center. Under transrectal or transperineal ultrasound and/or CT/MRI fusion guidance, the interventional urology or interventional radiology team inserts one or more probes percutaneously into the prostate tumor(s). The device delivers irreversible electroporation (IRE) electrical pulses to ablate tumor cells while preserving surrounding structures. Intra-procedural imaging guidance and neurovascular bundle assessment are performed. Post-procedure, the patient is observed for urinary retention, hematuria, and pain, receives discharge instructions, and returns for follow-up PSA monitoring and imaging as indicated.
Coding Specifications
| Modifier | Description | When to Use |
|---|
25 | Significant, separately identifiable evaluation and management service by the same physician on the same day of the procedure | Use when a separate E/M visit for pre- or post-procedure management is medically necessary and documented on the same day as the IRE procedure. |
59 | Distinct procedural service | Use when another procedure performed on the same day is separate and distinct from the IRE ablation and documentation supports separate anatomic site or separate session.
26 | Professional component | Use if only the professional component of an imaging study or interpretation related to the procedure is billed separately from facility services.
TC | Technical component | Use when the facility bills for the technical component of an imaging service used during the procedure.
52 | Reduced services | Use when the procedure is partially reduced or not completed as reported and documentation supports a reduced service.
53 | Discontinued procedure | Use when the procedure is started but discontinued due to extenuating circumstances and documentation supports discontinuation.
GA | Waiver of liability statement on file (ABN equivalent) | Use when the provider obtains a voluntary waiver for services that may be denied by Medicare/other payors, per local policy.
GZ | Unchecked or denied advance beneficiary notice (Medicare) — service expected to be denied as not reasonable and necessary | Use when no ABN/waiver is on file but service is billed and anticipated to be non-covered.
XE | Separate encounter, a service that is distinct because it occurred during a separate encounter | Use to indicate a distinct encounter for a procedure separate from the IRE session when appropriate.
LT | Left side | Use when laterality modifiers are needed and the procedure is performed on the left prostate lobe or targeted left-sided lesion (if payor requires laterality reporting).
