Pressure ulcer excision with bone involvement → CPT 15937 (sacral, with ostectomy)

Stage 4 pressure ulcer → L89.156 (sacral region with necrosis of bone)

For a patient with a mass in the left lower lung suspected to be cancer that is currently documented as a tumor of uncertain behavior, with existing ovarian cancer with metastases to the liver, the ICD-10-CM codes are:

D38.1: Neoplasm of uncertain behavior of bronchus and lung.

C56.9: Malignant neoplasm of unspecified ovary.

C78.7: Secondary malignant neoplasm of liver and intrahepatic bile duct.

D38.1 is used because the behavior of the lung tumor is uncertain, and C56.9 and C78.7 are used to document the known primary and metastatic cancers.

A “subcutaneous cardiac rhythm monitor” describes animplantable loop recorder(insertable cardiac monitor) placed under the skin for long-term rhythm surveillance. When the entire monitor system isremoved, CPT provides a specific removal code rather than using pacemaker/ICD removal codes.33286is the CPT code forremoval of an insertable cardiac monitor. The timing (14 months after implantation) supports that this is not an immediate post-op revision but a standard removal after monitoring is complete or the device is no longer needed. The distractors represent other cardiac device services:33241is removal of an implantable defibrillator pulse generator (not a loop recorder), and33272/33273relate to other cardiac device procedures rather than removal of an insertable monitor. CPC strategy: identify the device category—loop recorder/insertable cardiac monitor—and match the service—removal—to the dedicated code. This avoids incorrectly reporting pacemaker/ICD codes, which are different devices with different procedural work and coding families.

The CABG procedure involved multiple bypasses, with the use of autologous saphenous vein grafts and the left internal mammary artery, along with an extensive modified MAZE procedure. CPT® code 33535 describes a coronary artery bypass using arterial grafts, including at least three coronary artery bypasses. CPT® code 33259-51 is for the MAZE procedure for supraventricular tachycardia, with the -51 modifier indicating multiple procedures. CPT® code 33519-51 is for an additional vein graft, and CPT® code 33508-51 describes the endoscopic harvesting of the vein.

For ERCP, CPT coding follows the rule that thetherapeutic ERCP code includes the diagnostic ERCP workperformed during the same session. In this case, the key performed service isstent insertion into the biliary duct, which is captured by43274(ERCP with placement of endoscopic stent into biliary or pancreatic duct). You donotseparately report the diagnostic ERCP code43260when the therapeutic service (stent placement) is performed, because the diagnostic component is considered part of the overall ERCP service. Code43276is used forstent removal and/or exchange, which is not described here. Option D is incorrect because it pairs another ERCP service with stent placement, and the scenario does not support multiple distinct ERCP therapeutic services beyond stenting. CPC exam tip: when a single ERCP session includes diagnostic evaluation plus a therapeutic intervention, report themost definitive therapeutic ERCP code—here,43274.

33016 = Pericardiocentesis, including imaging guidance (e.g., ultrasound) when performed.Because the code already includes imaging guidance, you do not separately report 76942.So the correct coding is 33016 only → B.

In this encounter, the correct coding order follows ICD-10-CM guidelines for coding multiple conditions when AIDS (B20) is documented, as it takes precedence. The patient ' s diagnosis of AIDS, documented with code B20, is reported as the primary diagnosis since it is a chronic condition. The M17.31 code is used to document unilateral primary osteoarthritis of the right knee, unrelated to AIDS but causing the patient ' s knee pain.

Explanation of each answer choice:

A. B20, M17.31: Correctly lists AIDS (B20) as the primary diagnosis and osteoarthritis of the right knee (M17.31) as the secondary diagnosis.

B. Z21, M08.861: Z21 represents asymptomatic HIV, not AIDS, which is incorrect here, and M08.861 is the code for juvenile idiopathic arthritis, not relevant in this case.

C. M17.11, B20: Incorrect as M17.11 is for unilateral primary osteoarthritis of the right knee, not left, and does not prioritize B20 as required.

D. M17.31, B20: Incorrect because it does not list B20 as the primary diagnosis, which is necessary per coding guidelines when AIDS is documented.

Thus, the correct answer is A. B20, M17.31.

Open Roux-en-Y Gastric Bypass: The procedure involves creating a small gastric pouch and anastomosing it to the jejunum.

CPT Code 43847: This code describes a surgical gastric restrictive procedure with gastric bypass for morbid obesity, open.

ICD-10-CM Code E66.01: This code represents morbid (severe) obesity due to excess calories.

ICD-10-CM Code Z68.42: This code indicates a BMI of 45.
