ICD-10-PCS Code For Ribs, 1 To 2: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 0P91 includes procedures performed to drain fluids and gases from ribs, specifically ribs one to two in the upper bones body system. These ICD-10-PCS codes are used for inpatient documentation when a clinician removes collections of fluid or gas from the first or second ribs to treat infection, hematoma, or other pathological accumulations. Accurate coding within the ICD-10-PCS 0P91 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Ribs, 1 To 2 Drainage Procedure Overview

This procedure group includes drainage of the first and second ribs within the upper bones body system. Procedures involve removing fluids or gases from the ribs, often using percutaneous or open techniques to evacuate collections that compromise pain control, respiratory function, or wound healing. Accurate ICD-10-PCS coding of these drainage procedures ensures the inpatient record reflects the clinical intervention and supports appropriate reimbursement.

When to Use

Use a code from this group when a clinician actively removes fluid or gas from rib one or rib two as part of inpatient treatment for infection, hematoma, seroma, or other accumulations. These codes apply when the primary procedure performed is drainage of those specific ribs, whether by needle, catheter, or incision and drainage.

Typical Clinical Scenarios

An elderly patient on anticoagulation presents to the emergency department with acute, expanding chest wall swelling and increasing pain over the first rib after minor trauma; imaging demonstrates a large subperiosteal hematoma dissecting along the first rib causing respiratory compromise. Inpatient drainage is performed to evacuate the hematoma and control the collection originating from rib one, using an open or percutaneous approach depending on stability and surgeon preference. Typical codes: 0P910ZZ, 0P913ZZ
A middle-aged patient with a chronic, draining sinus over the second rib after prior thoracic surgery is admitted for definitive management of persistent osteomyelitis with purulent collection localized to rib two; the plan is incision and drainage with placement of a drainage device to allow continuous evacuation and wound care. A targeted drainage procedure on the second rib is performed to remove infected material and permit sampling for culture. Typical codes: 0P9100Z, 0P9130Z
A younger patient develops an iatrogenic pneumatoceles and localized air collection adjacent to the first rib following complicated chest tube placement and is taken to the operating room for percutaneous endoscopic drainage to evacuate the entrapped gas and inspect the area for ongoing air leak. The percutaneous endoscopic drainage targets the first-rib region to resolve the collection and improve ventilation. Typical codes: 0P914ZZ, 0P9140Z
