ICD-10-PCS Code For Lumbosacral Disc: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 0SU4 includes procedures performed to supplement biological or synthetic material in the lumbosacral disc in the lower joints. These ICD-10-PCS codes are used for inpatient documentation when biological or synthetic material is placed to reinforce or augment the function of the lumbosacral disc. Accurate coding within the ICD-10-PCS 0SU4 group is essential for proper inpatient reimbursement, as it captures the procedure performed and determines appropriate case mix and payment.

Typical Clinical Scenarios

An elderly patient with progressive neurogenic claudication and imaging-confirmed degenerative disc disruption at L5-S1 causing significant mechanical instability and refractory low back pain is admitted for an elective inpatient augmentation of the lumbosacral disc to restore disc height and provide structural support when conservative care has failed. The procedure is planned and performed to place a biologic or synthetic scaffold into the damaged disc to reinforce its function and alleviate symptoms. Typical codes: 0SU40JZ, 0SU407Z
A middle-aged patient presents urgently after a traumatic burst injury to the lumbosacral junction with partial loss of disc integrity and acute worsening of radicular pain; the surgical team performs an inpatient supplemental implantation of a synthetic spacer into the lumbosacral disc via a percutaneous approach to stabilize the disc and prevent further neurologic compromise. This acute inpatient intervention places reinforcing material into the disc to augment structural support following trauma. Typical codes: 0SU43JZ
A patient with prior discectomy and previous nonautologous graft placement at L4-L5 develops progressive disc collapse and recurrent symptoms during a readmission for revision; the surgeon performs a percutaneous endoscopic supplement procedure to replace or augment the prior material with either autologous tissue or a synthetic substitute to restore disc function and address the failed prior augmentation. The revision inpatient procedure specifically targets the lumbosacral disc to augment it with new reinforcing material. Typical codes: 0SU44KZ, 0SU447Z
