CPC Exam Dumps : Certified Professional Coder (CPC) Exam

The patient has undergone a left total knee arthroplasty and subsequently received a femoral nerve block for postoperative pain management. CPT code 01402 is used for anesthesia for total knee arthroplasty. Code 64447-59-LT is for a femoral nerve block (single injection) for postoperative pain management, with modifier 59 indicating a distinct procedural service and LT indicating the left side. Therefore, the appropriate codes are 01402 and 64447-59-LT.

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.

“Nephr/o” is the combining form meaningkidney, and “-logy” meansstudy of. Therefore,nephrologyis the medical specialty focused on the kidneys—normal kidney function, kidney diseases, and their medical management. In CPC-style terminology questions, look for the body-system root first (nephr = kidney) and then confirm the suffix. This differs fromurology, which is a surgical specialty addressing the urinary tract and male reproductive system. Endocrinology relates to hormones and glands, neurology relates to the nervous system, and cardiology relates to the heart. A quick word-building check helps avoid distractors: nephrology = kidney; cardiology = heart; neurology = nerves/brain; endocrinology = endocrine glands. On the CPC exam, recognizing common combining forms (nephr/o, ren/o) and suffix patterns (-logy, -itis, -ectomy) is a frequent testing strategy, so anchoring on “nephr” reliably identifies the correct specialty.
