What Concussion ICD Codes Can I Use?

If you’re looking for Concussion ICD codes, here are nine codes that you can use:

  1. 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.

  1. 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.

  1. 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).

  1. 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.

  1. 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.

  1. 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.

  1. 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.

  1. 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.

  1. 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.

Are These Concussion ICD Codes Billable?

Yes. All the aforementioned Concussion-related ICD-10 codes are valid and billable.

Clinical Information About Concussions

A concussion is a traumatic brain injury that temporarily disrupting the brain’s functioning. It’s caused by blows to the head that are strong enough to whip the brain back and forth inside the skull. It’s not limited to blows. Concussions can also be caused by blows to the body that are strong enough to make the head move rapidly and, in turn, move the brain rapidly.

It’s likely for a person to sustain a concussion if they bump their head on something hard if someone strikes their head, or if they get into some other accident that causes whiplash or hits their head, like vehicular accidents.

A person with a concussion will likely feel the following symptoms:

  • They will feel dazed and confused
  • Headaches and pressure in the head
  • Nausea
  • Sudden sensitivity to light
  • Memory problems
  • They will have trouble sleeping
  • They will feel fatigued

Synonyms Include

  • Concussion injury of the brain
  • Concussion with no loss of consciousness
  • Concussion injury of the cerebrum
  • Concussion with less than 1 hour loss of consciousness
  • Concussion with loss of consciousness
  • Traumatic brain injury with no loss of consciousness

Commonly asked questions

How long do concussions last?

More often than not, concussions should go away after a while. It may take a few days or weeks before it goes away, assuming they’re getting medically treated.

How do healthcare professionals treat people with concussions?

Healthcare professionals will prescribe pain relievers to deal with the pain and recommend avoiding activities that may put them at risk of hurting their heads. They also recommend drinking enough fluids, avoiding alcohol, avoiding looking at screens too much, and simply resting until they get cleared.

What happens if a person gets concussions again down the line?

Sustaining multiple concussions, even if far apart from each other, puts a person at risk of developing Chronic Traumatic Encephalopathy (CTE), which is a dangerous brain disorder characterized by loss of impulse control, memory loss, depression, suicidal thoughts and behavior, heightened aggression and irritability, and dementia.
