Disorders of visual pathways in (due to) neoplasm, left side

This code describes vision problems or damage to the nerves and pathways that carry visual information from the eye to the brain, specifically on the left side of the body, caused by a tumor or cancer. The tumor is pressing on or affecting these visual pathways, which can result in vision loss or other sight disturbances.

Buddy Documentation Tip

HCC Buddy guidance

Always verify the underlying neoplasm code and sequence it as the primary diagnosis before this code, as this is a manifestation code indicating the visual pathway disorder is due to the tumor

Confirm the laterality is documented as left side in the medical record; if bilateral or right-sided involvement exists, use the appropriate laterality code (H47.521 for right, H47.523 for bilateral)
