AAPC CPC Exam With Confidence Using Practice Dumps

55970 = Female-to-male sex transformation

55980 is for male-to-female transformation

Unlisted codes (58999, 55899) are not used when a specific CPT® code exists

1. Procedure and CPT® Code Selection:

The patient initially underwent a laparoscopic total abdominal hysterectomy for endometriosis of the uterus. However, due to extensive adhesions, the surgeon converted the procedure to an open total abdominal hysterectomy to complete the surgery.

CPT® Code 58150 is appropriate for a total abdominal hysterectomy, including removal of the uterus and cervix, via an open approach. Since the procedure was converted to an open approach, 58150 is the correct code.

The -22 modifier is added to indicate increased procedural services due to the extensive adhesiolysis (removal of adhesions), which extended the surgery duration.

2. Diagnosis and ICD-10-CM Code Selection:

ICD-10-CM Code N80.00 is used for endometriosis of the uterus, which is the primary condition that prompted the hysterectomy.

ICD-10-CM Code N73.6 is appropriate for female pelvic peritoneal adhesions, reflecting the extensive adhesions that necessitated the conversion to open surgery.

3. Rationale for Excluding Other Options:

Code 58571 (in options B and C) is for a laparoscopic approach, which is incorrect because the procedure was converted to an open approach.

The -78 modifier is incorrect in this context because the conversion to open surgery was part of the same operative session and not an unplanned return to the OR.

Diagnosis code N99.4 (in options B and D) pertains to postprocedural pelvic adhesions, which does not apply here as the adhesions were not due to a prior procedure.

4. AAPC and CPT® Coding Guidelines:

AAPC guidelines specify using 58150 for an open total abdominal hysterectomy and adding the -22 modifier for increased complexity or time due to factors like extensive adhesiolysis.

Therefore, the correct answer based on CPT® and ICD-10-CM guidelines is A. 58150-22, N80.00, N73.6.

The operative note describes anopen radical hysterectomyfor endometrial cancer with removal of theuterus, tubes, and ovaries(specimens listed) and extensive dissection ofuterine arteries, uterosacral and cardinal ligaments, consistent with aradicalprocedure. The approach is clearlyabdominal/open(midline vertical incision and abdominal entry), not laparoscopic, so a laparoscopic radical hysterectomy code (such as 58548) is not appropriate. In the answer set,58210represents aradical abdominal hysterectomy(with appropriate extent for malignancy management). In addition, the surgeon performedpelvic lymph node samplingbilaterally, removing lymphatic tissue along the iliac vessels to the obturator nerve region. The correct code in the choices for pelvic lymphadenectomy/sampling is38770. Pelvic washings and extensive exploration are included in the primary surgical service and do not add separate CPT codes in this scenario. Therefore, the correct coding combination is58210 and 38770.
