AAPC CPC - Certified Professional Coder (CPC) Exam

For bronchoscopy coding, you report the CPT code that describes thetype of scopeand thekey procedure performed. When bronchoscopicbiopsiesare performed, the service is reported with the appropriate bronchoscopy-with-biopsy code, and youdo not multiply the code by the number of biopsy samples. CPT codes for endoscopy procedures generally represent theoverall service, regardless of how many specimens are obtained during that one session at the same anatomic site category. In this question set,31628is the correct code representingflexible bronchoscopy with transbronchial lung biopsy(the biopsy component is the coded element).31625describes bronchoscopy with a different work element (not the biopsy service intended here), making it an incorrect distractor. Options that apply “×5” reflect a common novice error—billing per specimen rather than per procedure. On CPC exams, the presence of multiple biopsies is usually included to test whether you understand that endoscopic biopsy codes arenot reported per sample.

Break the term into parts:“oophor-”refers to theovary, and“-ectomy”meanssurgical removal/excision. The modifier“bilateral”meansboth sides(right and left). Put together,bilateral oophorectomymeanssurgical removal of both ovaries. This is commonly confused withsalpingectomy(removal of fallopian tube[s]) andhysterectomy(removal of uterus). CPC terminology questions often use these closely related female-reproductive terms as distractors, so the safest approach is to anchor on the root: “oophor” = ovary, “salping” = fallopian tube, “hyster/uter” = uterus. If it were removal of both tubes, it would bebilateral salpingectomy; removal of uterus (open or laparoscopic) is still a hysterectomy, not an oophorectomy. The “bilateral” part is critical—without it, an oophorectomy could be unilateral (one ovary).

According to the CPT® guidelines for Repair (Closure), an intermediate repair includes the closure of a wound with one or more layers of subcutaneous tissue and superficial fascia in addition to the skin (epidermal and dermal) closure. It also involves extensive cleaning of the wound, which includes copious irrigation and the removal of particulate matter. This description fits the scenario provided in the question.

The scenario describes an emergency basic life support (BLS) ambulance service. The appropriate HCPCS Level II code for BLS emergency transport is A0429.

Modifier QN indicates that the service was provided by an ambulance supplier, and SH indicates the services were provided in an emergency situation.

For the injections, CPT® code 64642 is used for chemodenervation of one extremity; 64643 for each additional extremity, and 64647 for chemodenervation of muscles in the paraspinal region. The modifier -50 is added to 64642 and 64643 to indicate bilateral procedures. According to CPT® guidelines, when multiple sites are treated, each site is coded separately, and appropriate modifiers are used.

The National Correct Coding Initiative (NCCI) was developed by CMS to:

Prevent unbundling

Define procedure-to-procedure (PTP) edits

Identify when modifiers (such as -59) may be appropriate

NCCI edits are critical for accurate CPT® coding and proper reimbursement.

The patient presents for a planned cesarean section for triplets and receives continuous epidural anesthesia. CPT code 01967 is used for neuraxial labor analgesia/anesthesia for planned vaginal delivery, and code 01968 is an add-on code for cesarean delivery following neuraxial labor analgesia/anesthesia. Since this is a planned cesarean section with triplets, both codes 01967 and 01968 are applicable.

22514 = Vertebroplasty, lumbar (L5)

22515 = Each additional vertebral body (sacrum)

Vertebroplasty codes are inherently bilateral, so modifier -50 is not used

This scenario describes an anterior discectomy and arthroplasty at two levels (L3-L4 and L5-S1) using artificial discs. CPT® code 22857 describes total disc arthroplasty (artificial disc), anterior approach, including discectomy to prepare interspace (other than for decompression), single interspace, lumbar. Since the procedure was performed at two levels, the code should be reported twice.

Repair of wound dehiscence → CPT 13160 (complex repair, secondary closure)

Occurs during global period and is unplanned → Modifier -78

Modifier -58 is for staged or planned procedures.
