What 53850 covers

During transurethral microwave thermotherapy, a urologist passes a treatment catheter through the urethra and delivers microwave energy to heat prostate tissue contributing to bladder-outlet obstruction. The procedure is used for men with bothersome lower urinary tract symptoms associated with benign prostatic enlargement, such as weak stream, hesitancy, or frequency. It is generally performed in an outpatient urology setting.

Report this code for the microwave treatment, not for radiofrequency or water-vapor prostate therapy. Documentation should identify the prostate condition, symptoms, and treatment method. The 90-day global includes the day-before preoperative visit and related postoperative care during the 90 days after surgery. When other procedures occur in the same session, the highest-valued procedure is paid in full and additional procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery services are not paid, and co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

53850 billing questions

How does this differ from CPT 53852?

CPT 53850 is for microwave thermotherapy. CPT 53852 is for transurethral radiofrequency thermotherapy.

How does this differ from CPT 53854?

CPT 53854 describes prostate tissue destruction using radiofrequency-generated water vapor. CPT 53850 uses microwave energy delivered through a treatment catheter.

Should modifier 50 be appended?

No. The descriptor and anatomy make bilateral adjustment inappropriate.

What postoperative care is included?

The 90-day global includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.

What happens when another procedure is performed in the same session?

The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction.

What should the record support?

Document the prostate condition and symptoms, and identify microwave thermotherapy as the treatment performed.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
