ICD-10-PCS Code For Olfactory Nerve: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 00DF includes procedures performed to extract nerve tissue in the olfactory nerve. These ICD-10-PCS codes are used for inpatient documentation when an extraction of all or a portion of the olfactory nerve is performed. Accurate coding within the ICD-10-PCS 00DF group is essential for proper inpatient reimbursement, as it captures the specific procedure performed and supports clinical documentation accuracy.

Olfactory Nerve Extraction Procedure Overview

This procedure group includes extraction procedures performed on the olfactory nerve within the central nervous system and cranial nerves. These procedures involve pulling or stripping out all or a portion of the olfactory nerve by the use of force. Accurate ICD-10-PCS coding for these extractions ensures inpatient records reflect the specific operation and anatomical target, which affects case mix grouping and reimbursement.

Typical Clinical Scenarios

An older adult with a rapidly expanding sinonasal malignancy involving the cribriform plate presents with progressive anosmia, epistaxis, and imaging showing tumor invasion of the olfactory nerve. Because disease control requires removal of involved neural tissue contiguous with the tumor, an inpatient open surgical extraction of the affected olfactory nerve is performed as part of the oncologic resection. Typical codes: 00DF0ZZ
A middle-aged patient with severe traumatic avulsion of the olfactory region after a motor vehicle collision is admitted for acute neurosurgical management of cranial base injuries; intraoperative findings include a nonviable segment of olfactory nerve that must be removed to control cerebrospinal fluid leak and prevent infection. In this acute operative setting, a percutaneous approach to extract the damaged olfactory nerve may be used to address the complication of trauma. Typical codes: 00DF3ZZ
A patient with a chronic, recurrent cerebrospinal fluid leak and persistent sinonasal infection after prior endoscopic skull base surgery is taken back for revision endoscopic debridement; intraoperative assessment shows dysfunctional, fibrotic olfactory nerve tissue that is hindering repair, and the surgeon removes the diseased portion endoscopically to facilitate definitive closure. Typical codes: 00DF4ZZ
