Sperm Washing for Artificial Insemination
Sperm washing for use in artificial insemination. Covers sperm preparation techniques that separate motile sperm from seminal plasma, debris, and non-motile sperm — required before IUI to reduce risk of uterine cramping and improve sperm quality.
Billing Notes
58323 is frequently omitted in IUI billing — it is a distinct, separately billable component from the IUI procedure (58322). Always bill 58323 alongside 58322 when sperm washing is performed, which is standard practice for IUI.
Diagnosis Codes
N97.x (infertility), N46.x (male factor), Z31.1 (AI encounter)
Common Denial Reasons
- Not billed — bundled into IUI fee incorrectly
- Not covered as a separate service by payer (rare but occurs)
- Missing documentation of processing method
Payer Notes
Most commercial payers with IUI coverage also cover sperm washing as part of the service. Bill 58323 on the same date as 58322.
