Question 1
Patient presents to the emergency department with multiple lacerations due to a knife fight at the local bar. After examination, it was determined these lacerations could be closed using local anesthesia. The areas were prepped and draped in the usual sterile fashion. The surgeon documented the following closures: 7.6 cm simple closure of the right forearm; 5.7 cm intermediate closure of the upper right arm; 4.7 cm complex closure of the right neck; 10.3 cm intermediate closure of the upper chest. What CPT® codes are reported?
Correct Answer:
13132, 12035-59, 12004-59
Explanation:
Rationale: Four lacerations are repaired. The lacerations are separated first by classification (simple, intermediate, complex); then by location. There is one simple closure which is 7.6 for the right forearm (12004). Next the intermediate closures are performed on the arm measuring 5.7 cm and the upper chest measuring 10.3 cm. Trunk (chest) and extremities (arm) are in the same classification and are both intermediate, so the lengths are added together to total 16 cm (12035). The last repair is a complex repair of the neck, 4.7 cm (13132). Subsection guidelines state to append Modifier 59 to indicate that multiple repair procedures are performed
Question 2
Patient presents to the operative suite with a biopsy proven squamous cell carcinoma of the left ankle. A decision was made to remove the lesion and apply a split thickness skin graft on the site. The lesion was excised as drawn and documented as measuring 2.4 cm with margins. Using the Padgett dermatone the surgeon harvested a split-thickness skin graft from the left thigh, which was meshed 1.5 x 1 and then inset into the ankle wound using a skin stapler. Xeroform bolster was then placed on the skin graft using Xeroform and 4-0 nylon and the lower extremity was wrapped with bulky cast padding and double Ace wrap. The skin graft donor site was dressed with OpSite. The surgeon noted the skin graft measured 9cm² in total. What CPT ® and ICD-9-CM codes are reported?
Correct Answer:
15100, 11603-51, 173.72
Explanation:
Rationale: The excision of the lesion is found by looking in the CPT® Index for Skin/Excision/Lesion/ Malignant, you are referred to code range 11600-11646. The lesion is on the ankle (leg) narrowing the code range to 11600-11606. The lesion is 2.4 cm making the correct code 11603. The guidelines for Excision – Malignant Lesions tell us to report reconstructive closure (15002-15261, 15570-15770) separately. In this case a split thickness skin graft was used. Look in the CPT® Index for Skin Graft and Flap/Split Graft which refers us to code range 15100-15101, 15120-15121. 15100 is the correct code choice. The diagnosis is squamous cell carcinoma. Look in the Neoplasm Table for skin/ankle and there is a note to ―see also Neoplasm, skin, limb, lower.‖ Skin/limb/lower gives us a subterm for squamous cell carcinoma (173.72
Question 3
Patient presents with a suspicious lesion on her left arm. With the patient’s permission the physician marked the area for excision. The lesion measured 0.9 cm. The wound measuring 1.2 cm was closed in layers using 4-0 Monocryl and 5-0 Prolene. Pathology later reported the lesion to be a sebaceous cyst. What codes are reported?
Correct Answer:
12031, 11401-51, 706.2
Explanation:
Rationale: Understanding a sebaceous cyst is benign, look in the CPT® Index for Skin/Excision/Lesion/Benign referring you to code range 11400-11471. The lesion is coded based on size and location for 11401. The note also indicates the wound was closed in layers allowing for intermediate closure, also coded based on location and size, 12031. In the ICD-9-CM Index, look under Cyst/sebaceous; or Cyst/skin (sebaceous is a nonessential modifier). Both options direct you to 706.2. Verify in the Tabular List
Question 4
30, 173.30, 238.2, 239.2
Correct Answer:
See solution for the supported answer
Explanation:
Rationale: For basal cell carcinoma, forehead, look in the ICD-9-CM codebook for the Neoplasm Table, then for Skin/forehead and there is note to ―see also Neoplasm, skin, face.‖ Neoplasm, neoplasia/skin/face/basal cell carcinoma refers you to code 173.31. Next, is a basal cell carcinoma, right cheek which also directs you to ―see also Neoplasm, skin, face.‖ (173.31). Because both basal cell carcinomas are coded with the same diagnosis code, it is only reported once. In the Index to Diseases, Nevus/compound has a morphology code of /0. Nevus/dermal/and epidermal also has a morphology code of /0. As noted in the Note box under the main term Nevus, morphology codes with a /0 should be coded to ―Neoplasm, skin, benign.‖ In the Neoplasm Table, look for skin/nose and skin/forehead both code to skin/face. The code from the benign column is used (216.3). Verify code selection in the Tabular List
Question 5
Operative Report Pre-Operative and Post-Operative Diagnosis: Squamous cell carcinoma, left leg Open wound, right leg Personal history of squamous cell carcinoma, right leg INDICATIONS FOR SURGERY: The patient is an 81-year-old white man with biopsy-proven squamous cell carcinoma of his left leg. I marked the areas for excision with gross normal margins of 5 mm, and I drew my planned skin graft donor site from his left lateral thigh. He also had an open wound of his right leg from a squamous cell carcinoma excised four months ago, the skin graft had not taken. We plan on re- skin grafting the area. The patient is aware of all of these markings, and understands the surgery and location. DESCRIPTION OF PROCEDURE: The patient was taken to the operating room. IV Ancef was given. I used plain lidocaine for his local anesthetic throughout the procedure until the skin grafts were inset. The anterior of his leg and the thigh were infiltrated with local anesthetic. Both upper extremities were prepped and draped circumferentially, which included the left thigh on the left side. I excised the lesion on his left leg as drawn into the subcutaneous fat. Hemostasis achieved with the Bovie cautery. I then excised the wound on his right leg to lower the bacterial counts. I took a 1-2 mm margin around the wound and excised the granulation tissue as well. Hemostasis was achieved using the Bovie cautery. I then changed gloves. A split-thickness skin graft was harvested from the left thigh using the Zimmer dermatome. This was meshed one and a half times one. By this time, the pathology returned showing the margins were clear. Skin grafts were inset on each leg wound using the skin stapler. Xeroform and gauze bolster was placed over the skin graft using 4-0 nylon. The skin graft donor site was dressed with OpSite. The legs were further dressed with heavy cast padding and the double Ace wrap. The patient tolerated the procedure well. PROCEDURES: Excision squamous cell carcinoma, left leg with excised diameter of 2.5 cm, repaired with a split-thickness skin graft measuring 5.1 cm² . Excisional preparation of right leg wound repaired with a split-thickness skin graft measuring 3.2 cm² . What CPT® codes are reported? 15100, 11603-51-LT, 15002-5-RT1, 15100, 15100-51-LT, 11603-51-LT, 15002-51-RT 15100, 11403-51-LT, 15100-51-RT 15100, 11603-LT
Correct Answer:
See solution for the supported answer
Explanation:
Rationale: The first excision is for a malignant neoplasm of the left leg measuring 2.5 cm (11603) and repaired with a split thickness skin graft measuring 5.1 sq cm. The second excision is a surgical wound preparation of an open wound to the right leg (15002) which was repaired with a split thickness autograft measuring 3.2 cm² . Split thickness autografts are added together for a total graft size of 8.3 cm² (15100). Becaluse the original surgery on the right leg was four months ago, this surgery is outside of any global period, so no additional modifier is needed. Modifier 51 is used to indicate multiple procedures
