What 58323 covers
Sperm washing processes a semen specimen to separate sperm from seminal fluid and other material and concentrate sperm for insemination. Fertility laboratory personnel typically prepare the specimen for a reproductive endocrinologist or other clinician performing artificial insemination in a fertility clinic or related setting. The washing service prepares the sample; it does not describe placing it in the reproductive tract.
Report 58323 when sperm washing is performed for artificial insemination, supported by documentation of the specimen preparation and its intended use. When insemination is also performed, report the applicable insemination service separately; same-session multiple-procedure payment reduction may apply, with the highest-valued procedure paid in full and other procedures reduced. The 0-day global period includes same-day preoperative and postoperative care. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

How to choose
58323 billing questions
How is 58323 different from 58321 or 58322?
58323 covers washing the sperm specimen. Codes 58321 and 58322 describe the insemination route: intracervical and intrauterine, respectively.
Can 58323 be reported with an insemination code?
When sperm washing and insemination are both performed and documented, report 58323 for preparation and the applicable code for the insemination. Same-session multiple-procedure payment reduction may apply.
What documentation supports 58323?
Document that a semen specimen was washed and prepared for artificial insemination. The record should distinguish this preparation from the insemination procedure itself.
Should modifier 50 be appended?
No. Bilateral adjustment is not appropriate for this service, so modifier 50 should not be used.
What is included in the global period?
The 0-day global period includes same-day preoperative and postoperative care.
