ICD-10-PCS Code For Eye Left: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group B836 includes procedures performed to image ocular structures in the left eye. These ICD-10-PCS codes are used for inpatient documentation when magnetic resonance imaging of the left eye is performed to evaluate ocular pathology or preoperative conditions. Accurate coding within the ICD-10-PCS B836 group is essential for proper inpatient reimbursement, as it captures the imaging procedure performed and supports clinical documentation accuracy.

Eye, Left Magnetic Resonance Imaging Procedure Overview

This procedure group includes magnetic resonance imaging examinations of the left eye, targeting the ocular structures within the eye body system. Procedures capture multiplanar images developed from radiofrequency signals emitted by nuclei in ocular tissues excited within a magnetic field. Accurate ICD-10-PCS coding for these inpatient imaging procedures ensures the documented exam is correctly represented for case mix assignment and reimbursement.

When to Use

Use a code from this group when an inpatient magnetic resonance imaging study is performed specifically on the left eye to assess pathology, trauma, or preoperative planning. Select the code that corresponds to the left eye MRI procedure documented in the medical record.

ICD-10-PCS Codes

ICD-10-PCS Code	Description
B836Y0Z	Magnetic Resonance Imaging (MRI) of Left Eye using Other Contrast, Unenhanced and Enhanced
B836YZZ	Magnetic Resonance Imaging (MRI) of Left Eye using Other Contrast
B836ZZZ	Magnetic Resonance Imaging (MRI) of Left Eye

Typical Clinical Scenarios

An adult patient is admitted after blunt orbital trauma with worsening periorbital swelling, decreased visual acuity in the left eye, and concern for intraocular or optic nerve injury not adequately assessed by CT; an inpatient MRI of the left eye is performed to evaluate soft-tissue detail, globe integrity, and optic nerve involvement before surgical planning. Typical codes: B836ZZZ
A patient with a history of left-sided ocular melanoma is admitted for preoperative staging and surgical planning; high-resolution left eye MRI with contrast is obtained to delineate tumor extent, extraocular extension, and orbital invasion to guide the operative approach. Typical codes: B836Y0Z, B836YZZ
An inpatient with sudden, painful vision loss in the left eye and suspected inflammatory or demyelinating optic neuropathy (eg, atypical optic neuritis) undergoes MRI of the left eye to identify optic nerve enhancement and surrounding inflammatory changes, aiding urgent treatment decisions and monitoring for complications. Typical codes: B836YZZ, B836ZZZ
