What is the appropriate code for the complete removal of ectopic pregnancy requiring fallopian tube excision?

The appropriate code for the complete removal of an ectopic pregnancy requiring fallopian tube excision is indeed 59151. This code specifically pertains to the surgical procedure for managing an ectopic pregnancy, which involves the excision of the fallopian tube where the ectopic tissue has implanted.

The code 59151 is classified under "Obstetrical Procedures" in the CPT coding system, indicating it concerns pregnancy-related operations, specifically detailing the surgical approach and removal of abnormal pregnancy tissue. The focus on the condition being ectopic and the requirement of tube excision aligns perfectly with this code's definition and intended use.

The other codes listed do not correspond to the right context for this procedure. For instance, codes like 33031 and 33512 pertain to procedures related to cardiovascular surgery, while 46753 is associated with more general surgical drainage procedures and does not specify anything related to obstetrics or gynecological surgical interventions. Thus, 59151 is the most accurate and specific choice for this scenario.
