Resection-Root Operation T​

Resection is similar to excision except it involves cutting out or off, without replacement, all of a body part. Resection includes all of a body part or any subdivision of a body part having its own body part value in ICD-10-PCS, while excision includes only a portion of a body part.

Examples of resection are total nephrectomy, total lobectomy of lung, total mastectomy, resection cecum, prostatectomy, or cholecystectomy.

Resection of a specific anatomical subdivision body part is coded whenever possible, rather than excision of the less specific body part (e.g., right upper lung lobectomy is coded to resection of upper lung lobe, right, and not to excision of lung, right).

The important distinction between excision and resection is if a portion or the entire body part is excised. A body part in ICD-10-PCS is not always an entire organ with some body part values being a subdivision of a particular organ. However, the body part value may be an entire organ, such as the organs of the gallbladder, prostate, or appendix.

When a procedure is performed on the body part, it is necessary to know if the entire body part was excised. A prostatectomy is the removal of the prostate, while a transurethral resection of the prostate removes the section of the prostate causing symptoms.

Some organs such as the liver, stomach, and lung have subdivisions of body parts. The liver contains right lobe and left lobe, the stomach includes the pylorus as a specific body part, and the lung has multiple body parts such as right and left upper lobe, right middle lobe, and right and left lower lobe.

Therefore if the entire right middle lobe of the lung was removed, resection would be assigned rather than excision, because this is a complete body part per ICD-10-PCS.

When an entire lymph node chain is cut out, the appropriate root operation is resection. When a lymph node(s) is cut out, the root operation is excision.
