Gynecologic procedure
About 58346: Heyman capsule uterine insertion
Reports placement of Heyman capsules through the cervix into the uterine cavity to position applicators for intracavitary radiation treatment.
A physician places Heyman capsules through the cervix into the uterine cavity to support intracavitary brachytherapy, commonly in treatment of cervical cancer. The capsules serve as applicators for positioning radiation sources; this code describes their insertion, not the radiation delivery itself. The service may be performed by a gynecologist or radiation oncologist in a setting equipped for the planned treatment.
Report 58346 when the documented procedure uses Heyman capsules, rather than a different uterine or vaginal applicator. The operative record should identify the applicator and document its placement. CMS classifies the service as major surgery: the day-before preoperative visit and 90 days of related postoperative care are included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment is restricted, and co-surgeons and team surgery are not permitted.

58346 billing questions
How does 58346 differ from 57155?
58346 is for Heyman capsule placement. Use 57155 when the physician places a uterine tandem and/or vaginal ovoid applicator instead.
Does 58346 include the radiation treatment?
The code describes placement of the Heyman capsules, not delivery of radiation. Intracavitary radiation source application, when performed and separately documented, is a distinct service.
What documentation supports reporting 58346?
The procedure note should identify Heyman capsules as the applicator and describe their placement in the uterine cavity.
Can modifier 50 be appended?
No. CMS identifies bilateral adjustment as inappropriate for this descriptor and anatomy.
Can an assistant or co-surgeon be paid for this procedure?
CMS applies a statutory restriction to assistant-at-surgery payment. Co-surgeons and team surgery are not permitted.
