About coding Conus medullaris spine contusion
The ICD-10-CM code for Conus medullaris spine contusion is S34.139 (Unspecified injury to sacral spinal cord).
Within S34.13, choose S34.139 (Unspecified injury to sacral spinal cord) only when documentation doesn't support a more specific option: complete lesion of sacral spinal cord (S34.131) and incomplete lesion of sacral spinal cord (S34.132).
Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.
