S06 is a non-billable ICD-10-CM category code for intracranial injury, so it cannot be submitted on claims. Use a more specific code from this category instead, such as S06.0X0A, S06.0X0D, S06.0X0S, and S06.0X1A.

Coding GuidelinesGuidance

The appropriate 7th character is to be added to each code from block Intracranial injury (S06). Use the following options for the applicable episode of care:

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela

Patient EducationClinical

Traumatic Brain Injury

Traumatic brain injury (TBI) is a sudden injury that causes damage to the brain. It may happen when there is a blow, bump, or jolt to the head. This is a closed head injury. A TBI can also happen when an object penetrates the skull. This is a penetrating injury.

Questions About S06Overview

Is S06 (Intracranial injury) a billable code?

No. This is a category header that groups the codes for intracranial injury, and headers cannot be submitted on claims. Claims for intracranial injury need a more specific code from this category, such as S06.0X0A, S06.0X0D, and S06.0X0S.
