Operation Definition

Cutting out or off, without replacement, all of a body part

Procedure Overview

Resection describes the complete surgical removal of an entire respiratory structure without replacing it, and in this body system it most often refers to pneumonectomy, the removal of an entire lung, most commonly performed for lung cancer that cannot be controlled with a smaller resection. It also covers total removal of a lobe when the whole lobe is taken, though partial lobe removal is classified differently.

These are major operations reserved for situations where disease, most often malignancy but sometimes severe infection or destroyed lung tissue, involves an entire anatomically distinct structure, making anything less than complete removal insufficient. Patients undergoing these procedures typically face a lasting reduction in lung capacity, so candidacy is carefully weighed against overall lung function beforehand.

Anatomy & Axis Detail

Upper Lung Lobe, Left

The left upper lobe is larger than its right-sided counterpart and encompasses both the true upper lobe segments and the lingula, since the left lung has only two lobes rather than three. Resection of this lobe is performed most often for lung cancer or, less commonly, for destructive infection confined to the upper portion of the left lung, and the procedure requires ligation of the upper division and lingular branches of the pulmonary artery along with the upper lobe bronchus and vein. Its close relationship to the aortic arch and left pulmonary artery main trunk demands careful hilar dissection to avoid injury to these structures. Complete removal of both the upper lobe proper and lingular tissue should be documented to support coding this as a full lobar resection.

Approach: Open

Open approach means the surgeon cuts through skin, mucous membrane, or other tissue layers to physically expose the target site to view before performing the procedure. It gives direct visualization and hands-on access, distinguishing it from Percutaneous approaches where instruments pass through a small puncture without exposing the site. Open is typical for procedures needing wide access, such as most laparotomies.

Coding & Documentation

The operative report must clearly state that an entire named anatomical unit, a whole lung, a whole lobe, or the whole trachea, was removed, since ICD-10-PCS Resection requires completeness of that structure. A frequent coding error is applying Resection to a lobectomy when only part of a lobe was actually removed, or applying it to a wedge resection of lung tissue, both of which should be coded as Excision because they remove only a portion of the body part.

Commonly Confused With

ExcisionThe essential distinction is with Excision, used whenever only a part of a respiratory structure is cut out rather than the whole named unit, such as a wedge resection or segmentectomy.
TransplantationIt's also distinct from Transplantation, since Resection removes tissue permanently without a replacement organ being implanted in the same family of codes.
