1. Procedure and CPT® Code Selection:

The scenario describes the excision of a 5 cm tumor located in the left lower quadrant of the abdominal wall. The tumor was excised down to the dermis and subcutaneous layers and removed using electrocautery.

Code 22903 is appropriate for the excision of a soft tissue tumor in the abdominal wall greater than 5 cm, making it the correct CPT® code.

Code 22901 applies to the excision of a soft tissue tumor in the abdominal wall but only for tumors 5 cm or less. Given that the tumor in this case is exactly 5 cm, it meets the threshold for 22903, which is more appropriate here.

2. Diagnosis and ICD-10-CM Code Selection:

ICD-10-CM Code D49.2 is used for a neoplasm of unspecified behavior in the abdominal area, reflecting the fact that the pathology report is pending to determine if the tumor is malignant.

Code C76.2 would be incorrect because it is for malignant neoplasms of unspecified abdominal areas, which we cannot confirm based on the initial excision. Similarly, R19.04 (indicating a mass in the abdominal region) is a symptom code and is not appropriate for a definitive diagnosis when a neoplasm code (D49.2) exists.

3. AAPC and CPT® Coding Guidelines:

Per AAPC coding guidelines, the size of the tumor is critical in selecting the correct excision code for abdominal wall neoplasms. Additionally, if the tumor’s pathology is not confirmed as malignant, it is coded as a neoplasm of unspecified behavior until further details are known.

Therefore, based on CPT® and ICD-10-CM coding guidelines, the verified answer is B. 22903, D49.2.
