Obstetrics procedure codes have a first character value of “1”. The second character value for body system is Pregnancy. The root operations Change, Drainage, Extraction, Insertion, Inspection, Removal, Repair, Reposition, Resection and Transplantation are used in the obstetrics section, and have the same meaning as in the medical and surgical section. The obstetrics section also includes two additional root operations, Abortion and Delivery, defined below:
The obstetrics section includes procedures performed on the products of conception only; procedures on the pregnant female are coded in the medical and surgical section (e.g., episiotomy). The term “products of conception” refers to all physical components of a pregnancy, including the fetus, amnion, umbilical cord and placenta. There is no differentiation of the products of conception based on gestational age. Thus, the specification of the products of conception as a zygote, embryo or fetus, or the trimester of the pregnancy, is not part of the procedure code but can be found in the diagnosis code.
The fifth character specifies approaches as defined in the medical and surgical section. The sixth character is used for devices such as fetal monitoring electrodes. Qualifier values are specific to the root operation, and are used to specify the type of extraction (e.g., low forceps, high forceps, low cervical cesarean, etc.), the type of fluid taken out during a drainage procedure (e.g., amniotic fluid, fetal blood, etc.) or the body system of the products of conception on which a repair was performed.
Choose from the sections below for accurate context:
All CHANGE procedures are coded using the approach EXTERNAL
The qualifier DIAGNOSTIC is used to identify drainage procedures that are biopsies
The qualifier DIAGNOSTIC is used to identify extraction procedures that are biopsies
Visual exploration may be performed with or without optical instrumentation. Manual exploration may be performed directly or through intervening body layers
If a device is taken out and a similar device put in without cutting or puncturing the skin or mucous membrane, the procedure is coded to the root operation CHANGE. Otherwise, the procedure for taking out a device is coded to the root operation REMOVAL
Used only when the method to accomplish the repair is not one of the other root operations
The body part is moved to a new location from an abnormal location, or from a normal location where it is not functioning correctly. The body part may or may not be cut out or off to be moved to the new location
The native body part may or may not be taken out, and the transplanted body part may take over all or a portion of its function
