Final answer:
The principal procedure code for an abortion performed by hysterotomy depends on the ICD edition and current coding guidelines, which may vary by location. The student should refer to the latest ICD manual for the accurate code.
Step-by-step explanation:
The student has asked for the principal procedure code for the case where Keyana Haulbrook, a 17-year-old female, 12 weeks gestation, underwent an abortion due to a genetic defect in the fetus using a hysterotomy technique. In medical coding, ICD codes (International Classification of Diseases) are used to record diagnoses and in-hospital procedures. The specific code for an abortion performed by hysterotomy will depend on the edition of ICD (e.g., ICD-10) and can vary by location and changes in coding practices.
Since the student has not specified the edition of the coding manual, I am unable to provide the exact code. It is essential for the student to refer to the current coding guidelines and the latest edition of the ICD manual for the accurate procedure code based on the details of the case.
