CPC Exam Dumps : Certified Professional Coder (CPC) Exam

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

Dacryocystitis is the inflammation of the lacrimal sac, which is part of the tear drainage system located in the inner corner of the eye. The lacrimal sac is connected to the nasolacrimal duct, which drains tears into the nasal cavity. Inflammation in this area can cause pain, redness, and swelling near the inner corner of the eye.

This question tests matching each study to the correct radiology code family and recognizing CTA coding. Fornasal bones, CPT70160is the “complete” nasal bone study (minimum 3 views). Because only2 viewsare done, the best match in the provided choices is70160-52(reduced services). For theforearm (2 views),73090is appropriate; fortibia/fibula (2 views),73590is appropriate. ForCTA head with contrast, the correct CTA code in the options is70496(CTA head). Option C is the only choice that correctly includes70496and the correct extremity X-ray codes73090and73590and also handles nasal bones as reduced service. The chest portion is imperfectly represented across the options (3-view chest typically aligns with a higher-view chest code than 71047), but the CPC-style best answerwithin the provided optionsisCbecause it captures the key intended learning targets: nasal bones reduced, correct extremity radiographs, and correct CTA head code.
