CPT_Exercises_Answer Key ACCOUNTING QUESTIONS WITH ANSWERS

The patient is seen as an outpatient for a bilateral mammogram. CPT Code: 77055-50 Note that the description for code 77055 is for a unilateral (one side) mammogram. 77056 is the correct code for a bilateral mammogram. Use of modifier -50 for bilateral is not appropriate when CPT code descriptions differentiate between unilateral and bilateral. 2. Physician performs a closed manipulation of a medial malleolus fracture—left ankle. CPT Code: 27766-LT The code represents an open treatment of the fracture, but the physician performed a closed manipulation. Correct code: 27762-LT 3. Surgeon performs a cystourethroscopy with dilation of a urethral stricture. CPT Code: 52341 The documentation states that it was a urethral stricture, but the CPT code identifies treatment of ureteral stricture. Correct code: 52281 4. The operative report states that the physician performed Strabismus surgery, requiring resection of the medial rectus muscle. CPT Code: 67314 The CPT code selection is for resection of one vertical muscle, but the medial rectus muscle is horizontal. Correct code: 67311 5. The chiropractor documents that he performed osteopathic manipulation on the neck and back (lumbar/thoracic). CPT Code: 98925 Note in the paragraph before code 98925, the body regions are identified. The neck would be the cervical region; the thoracic and lumbar regions are identified separately. Therefore, three body regions are identified. Correct code: 98926 Instructor's Guide AC: Basic CPT/HCPCS Exercises Page 2 of 101 6. The surgeon performs a colonoscopy with removal of a polyp by hot biopsy forceps. CPT Code: 45384 The documentation supports this CPT code selection. 7. A 45-year-old patient has a repair of a recurrent, incarcerated inguinal hernia. CPT Code: 49507 The documentation supports the selection of the code for “recurrent” not “initial.” Correct code: 49521 8. The surgeon performs an ERCP with endoscopic retrograde removal of a stone from the biliary duct. CPT Code: 43269 Code 43269 identifies ERCP for removal of a foreign body. Correct code: 43264 9. The surgeon performs an excision of a 1.5 cm deep intramuscular soft tissue tumor of the scalp. CPT Code: 21011 CPT distinguishes between an “intramuscular” soft tissue tumor excision from subcutaneous. Code 21011 is for a subcutaneous tumor, which does not match the documentation. Correct code: 21013 10. The physician performs a fine needle aspiration biopsy of the testis. CPT Code: 54500 Note the parenthetical statement beneath code 54500 that states: “(For fine needle aspiration, see 10021, 10022).” A coder would need further documentation to determine if the biopsy was performed with imaging guidance (CPT code 10022) or without imaging guidance (10021).
