Clinical & Coding Specifications
Clinical Context
A 32-year-old woman with a history of unexplained infertility presents to a reproductive endocrinology clinic after 12 months of unsuccessful conception while attempting timed intercourse. Her partner provides a semen sample that is processed in the laboratory to concentrate motile sperm (wash and preparation). The patient is scheduled for intrauterine insemination via the cervical canal where the prepared live sperm will be placed at or just beyond the cervical os using a catheter. The clinical workflow includes pre-procedure counseling, confirmation of no active infection, ovulation timing (natural cycle or with ovulation induction medications such as clomiphene or letrozole), semen collection and processing in the andrology lab, and the insemination procedure performed in an outpatient clinic exam room or a procedure room. Post-procedure instructions are given and a follow-up pregnancy test is arranged in approximately 2 weeks.
