What This Code Means
G57.02 is the ICD-10-CM diagnosis code for lesion of sciatic nerve, left lower limb. Damage or injury to the sciatic nerve on the left side of the body, causing pain, weakness, or numbness in the left leg. G57.02 sits in the ICD-10-CM chapter for diseases of the nervous system (g00-g99), within the section covering nerve, nerve root and plexus disorders (g50-g59).
G57.02 is a billable ICD-10-CM code, but the current payload does not show a mapping under the CMS-HCC V28 or V24 community payment models, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.
Verify documentation specifies left side involvement; do not assume laterality.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for G57.02 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify documentation specifies left side involvement; do not assume laterality
- •Investigate the underlying cause (trauma, compression, inflammation) for more specific coding if available
