Refer to the supplemental information when answering this question: View MR 623654 What CPTO coding is reported for this case?
Correct Answer: C
CPC Exam Question 47
A patient is brought to the operating room with a right-sided peripheral vertigo. The provider makes a postauricular incision and uses an operating microscope to perform a mastoidectomy using a burr. He next destroys the semicircular canals, the utricle, and saccule completely removing the diseased labyrinth structures. The provider sutures the incision. What CPTcode and ICD-10-CM codes are reported?
Correct Answer: D
Procedure Coding (CPT): 69910 - Labyrinthectomy, complete; transmastoid approach Provider performed: Mastoidectomy Complete destruction/removal of semicircular canals, utricle, and saccule This is a complete labyrinthectomy, not partial 69990 - Microsurgical techniques, requiring use of operating microscope Separately reportable with otologic procedures Modifier -51 not required (add-on code) Diagnosis Coding (ICD-10-CM): H81.391 - Peripheral vertigo, right ear Correct laterality and condition Why Other Options Are Incorrect: 69905 - Partial labyrinthectomy R42 - Symptom code (dizziness), not used when definitive diagnosis exists
CPC Exam Question 48
A patient is diagnosed with a healing pressure ulcer on her left heel that is currently being treated. What ICD-10-CM coding is reported?
Correct Answer: B
ICD-10-CM guidelines state that healing pressure ulcers are coded as the stage documented. L89.624 = Pressure ulcer of left heel, stage 4 Stage 4 ulcers involve full-thickness tissue loss and are commonly referenced in exam scenarios involving treatment of healing ulcers Unspecified stage or laterality codes are not appropriate when documentation supports specificity.
CPC Exam Question 49
Refer to the supplemental information when answering this question: View MR 000281 What anesthesia and diagnosis codes are reported for this case?
Correct Answer: D
CPT Code 00811: Anesthesia for lower intestinal endoscopic procedures, endoscope introduced distal to the splenic flexure; diagnostic, with or without collection of specimen(s) by brushing or washing This code is reported for anesthesia services provided during a colonoscopy that is diagnostic in nature. ICD-10-CM Code D62: Acute posthemorrhagic anemia This is the most accurate postoperative diagnosis. The operative report states "Anemia due to acute blood loss." ICD-10-CM Code N18.6: End stage renal disease This code captures the patient's documented history of ESRD. ICD-10-CM Code Z99.2: Dependence on renal dialysis This code is necessary to report the patient's dialysis status, as it affects the overall risk of the procedure. Why other options are incorrect: 00812: This code is for therapeutic colonoscopies, not diagnostic. D64.9: This code is for anemia, unspecified. D62 is more specific to the patient's condition. K62.5: This code is for lower gastrointestinal bleeding, but the anemia is the primary diagnosis in this case.

CPC Exam Question 50
(Patient is having an orchiectomy. Which part of the body is being performed on?)
Correct Answer: B
The key is the root and suffix:orch/o(or orchi/o) refers to thetestis/testicle, and-ectomymeanssurgical removal. Therefore,orchiectomyis the surgical removal of atesticle(one or both, depending on context). The distractors are nearby male reproductive structures that commonly appear in anatomy questions: thescrotumis the external sac that houses the testes (procedures there might be scrotoplasty or scrotal surgery, not orchiectomy). Theepididymisis the structure attached to the testicle where sperm mature and are stored (removal would be epididymectomy). Theprostateis a gland at the base of the bladder (removal would be prostatectomy). On the CPC exam, terminology questions often use anatomic proximity to tempt you into picking a "nearby" structure-always lock onto the combining form first (orch = testis), then confirm the procedure suffix (-ectomy = removal).
