Clinical & Coding Specifications
Clinical Context
A typical patient is a woman aged 30–55 presenting to a gynecology clinic with abnormal uterine bleeding, postmenopausal bleeding, or abnormal cervical cytology. After history, pelvic exam, and transvaginal ultrasound, the clinician recommends diagnostic and therapeutic endocervical curettage of the cervical stump to obtain tissue for histopathology and to remove retained endocervical tissue. The procedure is usually performed in an outpatient procedure room, ambulatory surgical center, or hospital outpatient department under local anesthesia, moderate sedation, or monitored anesthesia care depending on patient factors and institutional protocols. The workflow includes pre-procedure consent and time-out, placement of a speculum, visualization of the cervix, dilation if needed, insertion of a curette to sample endocervical tissue and cervical canal, immediate specimen labeling and submission to pathology, hemostasis and post-procedure recovery, and documentation of findings and specimens. Typical clinical indications include evaluation of abnormal bleeding, follow-up of abnormal Pap/HPV testing when endocervical sampling is required, and sampling when cervical stenosis or scarring is suspected.
