Asphenoidotomyperformed vianasal/sinus endoscopyis specifically reported withCPT 31287(endoscopic sinus surgery, sphenoidotomy). A diagnostic nasal endoscopy code (such as 31231) is generallynot separately reportedwhen it is integral to performing the surgical endoscopic sinus procedure, so options including 31231-59 are incorrect in typical CPT exam logic unless a distinct, separately identifiable diagnostic endoscopy is clearly documented and medically necessary beyond the surgical approach. The diagnosis describes afracture of the skull baseinvolving the sphenoid sinus without CSF leak; among the offered diagnosis codes,S02.19XAcorrectly represents a skull base fracture category consistent with the scenario’s specificity as presented in the answer choices. Code31291represents a different sinus procedure (not sphenoidotomy). CPC key point: choose the code matching thespecific sinus and surgical action(sphenoidotomy → 31287) and avoid unbundling the diagnostic endoscopy that is part of the operative endoscopic approach.

Atranstympanic(intratympanic) injection involves placing medication through the tympanic membrane into the middle ear space. CPT69801is used to report this transtympanic injection/tympanocentesis-type service as represented in CPC-style questions. Because the physician performed the injection inboth earsduring the same session, the appropriate bilateral reporting method in this answer set ismodifier -50to indicate abilateral procedure. Reporting69801 × 2is a common trap; many payers require either modifier 50 or RT/LT rather than two units, and the CPC exam typically follows modifier logic as presented in the options. Modifier-22(increased procedural services) would require unusual extra work beyond typical complexity and is not supported by the vignette. Reporting only a single unilateral code (option A) would underreport the bilateral nature. Therefore, the best answer is69801-50, reflecting the same service performed on paired organs during the same encounter.

00813 = Anesthesia for colonoscopy

QK = Medical direction of 2–4 cases

99100 = Extreme age

99140 = Emergency anesthesia

Frozen section pathology coding rules:

88331 – Frozen section, first tissue block, each specimen

88332 – Frozen section, each additional tissue block, same specimen

Breakdown:

Specimen 1

Block 1 → 88331 × 1

Block 2 → 88332 × 1

Specimen 2

Block 1 → 88331 × 1

Block 2 → 88332 × 1

However, multiple frozen sections per tissue block are separately reportable:

Total first blocks = 4 frozen sections → 88331 × 4

Total additional blocks = 3 frozen sections → 88332 × 3

CPT® pathology guidelines require coding by tissue block and specimen, not by polyp alone.

The documented study is atransvaginal pelvic ultrasound, which is coded with76830(ultrasound, transvaginal). Because the service is billed by anindependent radiologist providing only the interpretation, the correct reporting is theprofessional componentwith modifier-26(interpretation and report), not the global code. That makes76830-26the correct CPT selection. Code76817is fortransvaginal ultrasound in pregnancy/obstetric contexts, which is not supported here (the patient is menopausal and no pregnancy evaluation is described). For diagnosis, the chief complaint isuterine cramping, and the options provide pelvic pain codes;N94.89(other specified conditions associated with female genital organs and menstrual cycle) is the best match among the choices provided for uterine cramping/pelvic symptom documentation.N94.9is less specific (“unspecified”), so when a more specific option is available in the answer set, selectN94.89. Therefore, the correct combination for the interpreting independent radiologist is76830-26, N94.89.

The correct answer is B. Modifier 32. Modifier 32 identifies a mandated service, meaning the service was required by a third-party payer, governmental body, legal authority, employer, or other regulatory entity rather than being performed solely at the physician’s independent clinical discretion. In professional coding, this modifier communicates the reason the service was rendered and helps distinguish required examinations or evaluations from routine medically indicated services. Typical examples include services requested for insurance review, workers’ compensation requirements, legal determinations, disability evaluation, or other administrative mandates.

The other modifiers do not match the scenario. Modifier 23 is used for unusual anesthesia circumstances. Modifier 76 reports a repeat procedure or service performed by the same physician or other qualified health care professional. Modifier 24 is appended to an unrelated evaluation and management service performed during a postoperative global period. None of these indicate that the service was required by an external payer or regulatory authority.

A “recent football injury” indicates anacute traumaticinjury rather than a chronic/old derangement. Acute meniscus tears are coded from theS83.2-category (tear of meniscus, current injury), not theM23.-category (derangement of meniscus due to old tear or injury). The question specifiesmedial meniscus,left knee, and implies aninitial encounterfor the acute injury, so the correct code must include laterality and the 7th characterAfor initial encounter.S83.232Acorresponds to acurrent tear of the medial meniscus, left knee, initial encounter.S83.242Ais a different meniscus specification (not medial).M23.202/M23.204are derangement codes typically used forold tearsor chronic conditions, not an acute recent sports injury. CPC exam tip: “recent injury” →S-codes, “old tear/derangement” →M23. Mnemonic:S = Sudden (acute),M = Mature (old/chronic).

60220 = Total lobectomy, unilateral thyroid

60500 = Parathyroidectomy (single gland)

Modifier -59 is appropriate to indicate a distinct procedure

11403 = Excision of benign lesion, trunk, 2.1–3.0 cm

Simple closure is included in excision codes

No separate closure code is reported.

Correct answer: A

The CPT code 10005 is for fine needle aspiration biopsy, including ultrasound guidance, for the first lesion. CPT code 10006 is for each additional lesion with ultrasound guidance. Since the provider aspirated tissue from three nodules, the coding should be 10005 for the first nodule and 10006 x 2 for the additional two nodules.
