What Concussion ICD Codes Can I Use?
If you’re looking for Concussion ICD codes, here are nine codes that you can use:
- S06.0X0A - Concussion without loss of consciousness, initial encounter
This ICD-10 code is meant for patients who have sustained a concussion but didn’t lose consciousness when they sustained it. This code comes with the initial encounter label, meaning the patient is currently being treated for it.
- S06.0X0D - Concussion without loss of consciousness, subsequent encounter
This is the same as Item 1, but this time, it has the subsequent encounter label, meaning the patient is in recovery and is still being given active/routine care.
- S06.0X0S - Concussion without loss of consciousness, sequela
This is the same as Item 1, but this time, it has the sequela label, which means that the patient is dealing with the aftereffects of the concussions. Given this, this ICD-10 code should be accompanied by two other ICD-10 codes, one of which should designate the sequela’s nature, while the other should describe the sequela (meaning its effects).
- S06.0X9A - Concussion with loss of consciousness of unspecified duration, initial encounter
This ICD-10 code is meant for patients who have sustained a concussion and lost consciousness. How long they were unconscious since they suffered the concussion is unspecified. Once you’ve confirmed the length of time, which is 30 minutes or less, please use Items 7, 8, or 9. If the time is beyond 30 minutes, you can settle for this.
This code also comes with the initial encounter label.
- S06.0X9D - Concussion with loss of consciousness of unspecified duration, subsequent encounter
This is the same as Item 4, but this time, it has a subsequent encounter label.
- S06.0X9S - Concussion with loss of consciousness of unspecified duration, sequela
This is the same as Item 4, but it has a sequela label this time.
- S06.0X1A - Concussion with loss of consciousness of 30 minutes or less, initial encounter
This is similar to Item 4, but this time, the duration of the loss of consciousness is known, and it’s 30 minutes or less.
- S06.0X1D - Concussion with loss of consciousness of 30 minutes or less, subsequent encounter
This is similar to Item 7, but this time, it has a subsequent encounter label.
- S06.0X1S - Concussion with loss of consciousness of 30 minutes or less, sequela
This is similar to Item 7, but it has a sequela label this time.
