2025 Endometrial Cryoablation CPT Code
Bryant Schmitz • Updated Jun 30, 2025 • 89 hits
Endometrial cryoablation (CPT code 58356) is performed by gynecologists to ablate the uterine lining using cryogenic energy, typically with ultrasound guidance, to treat abnormal uterine bleeding or early-stage endometrial pathology. This minimally invasive procedure preserves the uterus while reducing bleeding. This article clarifies appropriate use and billing of CPT code 58356.

Detailed Description of CPT Code 58356
CPT Code: 58356
Code Description: Cryoablation of the endometrium, with or without ultrasonic guidance
Inclusions: Use of cryogenic probe, endometrial ablation via ultrasonic visualization, uterine ultrasound guidance, anesthesia, insertion and removal of instrumentation
Exclusions: Separate hysteroscopic endometrial ablation codes (e.g., thermal), dilation and curettage unless separately indicated, anesthesia services, pelvic ultrasound beyond procedural guidance
Coding & Billing Considerations
Append modifier 51 if cryoablation is performed with other procedures during the same operative session.
Use modifier 59 to differentiate from unrelated procedures on the same date.
Clearly document the use of ultrasonic guidance in the operative note.
Do not report alongside hysteroscopic ablation codes (e.g., 58353–58355) unless different modality used.
Describe cryotherapy technique, probe type, duration, and target area in documentation.
Verify payer policies for emerging technologies and coverage of ultrasonic guidance.
Why Proper Coding Is Important
Accurate coding with 58356 ensures proper reimbursement and reduces the risk of denials associated with experimental or specialized procedures. It supports clinical documentation by reflecting the use of ultrasonic guidance and cryogenic technique. Proper coding safeguards compliance with payer guidelines and clarifies procedural intent for future medical review.
What is a CPT Code?
CPT stands for Current Procedural Terminology. These codes are used by medical professionals to describe procedures and services performed. CPT codes are crucial for the billing process, allowing healthcare providers to communicate with insurance companies and other payers about the procedures performed.
