ICD-10-PCS Code For Respiratory System: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 6ABB includes procedures performed to perfuse therapeutic fluid in the respiratory system. These ICD-10-PCS codes are used for inpatient documentation when extracorporeal or systemic perfusion of the respiratory organs is performed to deliver or exchange therapeutic fluid. Accurate coding within the ICD-10-PCS 6ABB group is essential for proper inpatient reimbursement, as it captures the procedure performed and the anatomic target which determine case mix and payment.

Respiratory System Perfusion Procedure Overview

This procedure group includes perfusion procedures directed at the respiratory system, where therapeutic fluid is circulated extracorporeally or systemically to the respiratory organs. These procedures target the physiological systems body system and involve controlled diffusion or exchange of therapeutic substances to the respiratory system. Accurate coding of these perfusion procedures is important for inpatient reimbursement because it documents the specific operation and anatomic target that determine case mix and payment.

When to Use

Use a code from this group when therapeutic fluid is perfused to or through the respiratory system as part of extracorporeal or systemic therapy. Codes are appropriate when documentation indicates perfusion as the principal operation on the respiratory organs during the inpatient encounter, rather than another type of procedure or manipulation unrelated to perfusion activities.

ICD-10-PCS Code	Description
6ABB0BZ	Perfusion of Respiratory System Donor Organ, Single

Typical Clinical Scenarios

An adult donor is evaluated in the hospital after brain death for organ procurement; the respiratory donor organ (lungs) requires targeted perfusion with a therapeutic preservation solution to assess function and optimize viability prior to retrieval and transport, so extracorporeal perfusion of the respiratory system donor organ is performed as part of the organ preservation protocol. Typical codes: 6ABB0BZ
A middle-aged patient brought in urgently after near-drowning with severe pulmonary injury where a donor lung is being prepared for immediate transplant into the recipient; the procurement team performs extracorporeal perfusion of the respiratory donor organ to deliver protective fluids and evaluate graft suitability under time-sensitive conditions. Typical codes: 6ABB0BZ
During a planned living-donor lung lobectomy intended for transplantation, the donor respiratory organ segment designated for transfer is perfused ex vivo with preservation solution to maintain tissue viability and reduce ischemic injury before implantation into the recipient; this procedure is done in the inpatient surgical setting as part of the transplant workflow. Typical codes: 6ABB0BZ
