Question 1
The patient has a torn medial meniscus. An arthroscope was placed through the anterolateral portal for the diagnostic procedure. The patellofemoral joint showed grade 2 chondromalacia on the patellar side of the joint only, this was debrided with a 4.0-mm shaver. The medial compartment was also entered and a complex posterior horn tear of the medial meniscus was noted. It was probed to define its borders. A meniscectomy was carried out to a stable rim. What CPT® code(s) is reported?
Correct Answer:
29881, 29877-59
Explanation:
Rationale: In the CPT® Index, look for Arthroscopy/Surgical/Knee. You are referred to 29871-29889. Review the codes to choose appropriate service. 29881 is the correct code since the tear was in the ―medial meniscus‖. A meniscectomy as well as debridement with a shaver (or chondroplasty) were performed. 29877 would not be reported as this is covered with code 29881. 29880 is not appropriate as the procedure would have had to be performed on both the medial and lateral compartments. The surgery started out as a ―diagnostic procedure,‖ but changed when the physician decided to perform surgical procedures on the knee, rather than only examining the knee for diagnostic purposes
Question 2
A 3-year-old is brought into the ER crying. He cannot bend his left arm after his older brother pulled it. The physician performs an X-ray to diagnose the patient has a dislocated nursemaid’s elbow. The ER physician reduces the elbow successfully. The patient is able to move his arm again. The patient is referred to an orthopedist for follow-up care. What CPT® and ICD-9-CM codes are reported?
Correct Answer:
24640-54-LT, 832.2, E927.0
Explanation:
Rationale: In the CPT® index, look up Elbow/Dislocation/Closed Treatment. You are referred to 24600- 24605, and 24640. Review the codes to choose appropriate service. 24640 is the correct code to report treatment of a dislocated nursemaid’s elbow with manipulation. Modifier 54 is used to report that the ED physician performed the surgical portion of the service only. The patient is referred to an orthopedist for follow-up care. Modifier LT is appended to indicate the procedure was performed on the left side. In the ICD-9-CM Index to Diseases, look up Nursemaid’s/elbow. You are referred to 832.2. Review the code in the tabular section to verify accuracy. According to ICD-9-CM guidelines: A dislocation not indicated as closed or open should be classified as closed. In the ICD-9-CM Index to Diseases (Alphabetic Index) to External Causes of Injury and Poisoning, Section 3, look up Pulling,injury/due to/sudden strenuous movement. You are referred to code E927.0. Review the code in the Tabular List to verify accuracy
Question 3
A 50-year-old male had surgery on his upper leg one day ago and presents with serous drainage from the wound. He was taken back to the operating room for evaluation of a hematoma. His wound was explored, and there was a hematoma at the base of the wound, which was very carefully evacuated.The wound was irrigated with antibacterial solution. What CPT® and ICD-9-CM codes are reported?
Correct Answer:
27301-78, 998.12
Explanation:
Correct answer: 27301-78, 998.12
Question 4
A 22-year-old female sustained a dislocation of the right elbow with a medial epicondyle fracture while on vacation. The patient was put under general anesthesia and the elbow was reduced and was stable. The medial elbow was held in the appropriate position and was reduced in acceptable position and elevated to treat non-surgically. A long arm splint was applied. The patient is referred to an orthopedist when she returns to her home state in a few days. What CPT® code(s) are reported?
Correct Answer:
24565-54-RT, 24605-54-51-RT
Explanation:
Rationale: In the CPT® Index, look for Fracture/Humerus/Epicondyle/Closed Treatment. You are referred to code 24560-24565. Review the codes to choose the appropriate service. 24565 is the correct code to report an epicondyle fracture manipulated (reduced) without a surgical incision to perform the procedure. In the CPT® Index, look for Dislocation/Elbow/Closed Treatment. You are referred to 24600,24605. Review the codes to choose appropriate service. 24605 is the correct code because the patient was put under general anesthesia to perform the procedure. Modifier 54 is used to report the physician performed the surgical portion only. The patient is referred to an orthopedist for follow up or postoperative care. Modifier 51 is used to report multiple procedures were performed. Append modifier RT to indicate the procedure is performed on the right side
Question 5
A 45-year-old presents to the operating room with a right index trigger finger and left shoulder bursitis. The left shoulder was injected with 1 cc of Xylocaine, 1 cc of Celestone, and 1 cc of Marcaine. An incision was made over the A1 pulley in the distal transverse palmar crease, about an inch in length. This incision was taken through skin and subcutaneous tissue. The Al pulley was identified and released in its entirety. The wound was irrigated with antibiotic saline solution. The subcutaneous tissue was injected with Marcaine without epinephrine. The skin was closed with 4-0 Ethilon suture. Clean dressing was applied. What CPT® code(s) are reported?
Correct Answer:
26055-F6, 20610-76-LT
Explanation:
Rationale: In the CPT® Index, look for Trigger Finger Repair. You are referred to 26055. Review the code to verify accuracy. In the CPT® Index, look for Injection/Joint. You are referred to 20600-20610. Review the codes to choose appropriate service. 20610 is the correct code since the shoulder was injected. Modifier F6 is used to report the right index finger that was repaired. Modifier LT is used to indicate the left shoulder joint. Modifier 51 is used to indicate multiple procedures were performed
