Post-Concussion Syndrome ICD‑10: Understanding the Code, Symptoms, Causes & Legal Options
Post-concussion syndrome (PCS) is a condition where concussion symptoms continue long after the initial head injury has healed. While most concussions resolve within a few weeks, some people experience headaches, dizziness, cognitive problems, and sensory sensitivity for months—or even years. If your symptoms persist and disrupt your daily life, getting an accurate medical diagnosis is crucial, and that includes proper ICD‑10 coding.
This guide explains the post-concussion syndrome ICD‑10 code (F07.81), what PCS looks like, how it’s diagnosed, and why accurate documentation matters for treatment, insurance claims, and legal cases.
What Is the ICD‑10 Code for Post-Concussion Syndrome?
The ICD‑10 code for post-concussion syndrome is F07.81.
Doctors, neurologists, and hospitals use F07.81 to document PCS in medical records, insurance claims, and referrals. This code indicates that a patient is experiencing ongoing symptoms after a mild traumatic brain injury (mTBI) or concussion.
PCS symptoms may include:
- Chronic tension-type headaches
- Dizziness or balance problems
- Difficulty concentrating
- Short-term memory issues
- Irritability or mood changes
- Fatigue
- Sleep problems
- Light or noise sensitivity
Accurate ICD coding helps ensure patients receive appropriate diagnostic testing, rehabilitation, and follow‑up care.
What Is Post-Concussion Syndrome?
Post-concussion syndrome happens when concussion symptoms last beyond the normal recovery window, which is usually 2–6 weeks. Instead of improving steadily, PCS symptoms can linger or worsen over time.
Common PCS symptoms include:
Physical symptoms
- Headaches
- Nausea
- Fatigue
- Balance issues
- Sleep disruption
Sensory symptoms
- Light sensitivity
- Noise sensitivity
- Blurred or double vision
- Vertigo
Cognitive symptoms
- Slowed thinking
- Difficulty focusing
- Trouble organizing thoughts
- Memory problems
Emotional or behavioral symptoms
- Anxiety
- Irritability
- Mood swings
- Restlessness
- Depression
Some people recover within months, while others experience symptoms for years.
How Long Do Post-Concussion Symptoms Last?
Most concussion symptoms fade in a few weeks.
PCS symptoms can last months or years, depending on:
- Severity of the initial injury
- Number of past concussions
- Pre‑existing anxiety, depression, or ADHD
- Age and overall health
- Quality of medical care and rehabilitation
Some people also experience delayed symptoms—issues that appear weeks after the injury rather than immediately.
Common Causes of Post-Concussion Syndrome
PCS can develop after any incident involving head trauma or rapid head movement. Common causes include:
Auto Accidents
Rear-end collisions, sideswipe accidents, T-bone impacts, and rollovers can all cause concussions—even without a direct blow to the head.
Truck Accidents
Truck collisions often involve high force, creating a greater risk of long-term PCS symptoms.
Motorcycle Accidents
Riders and passengers are especially vulnerable to brain injuries due to minimal physical protection.
Pedestrian Accidents
Even low‑speed vehicle impacts can cause a pedestrian to strike their head or experience acceleration‑deceleration trauma.
Slip and Fall Accidents
A slip, trip, or fall can cause the head to hit the ground or another object, leading to brain injury.
Workplace Accidents
Falls from ladders, machinery incidents, and falling objects commonly cause concussions on job sites.
Sports-Related Injuries
Football, soccer, hockey, and other contact sports carry a higher risk of mild TBIs and repeated head trauma.
How Is Post-Concussion Syndrome Diagnosed?
PCS diagnosis usually includes:
- Medical history review
- Neurological exams
- Balance and coordination testing
- Cognitive assessments
- Neuropsychological testing
- Imaging (CT or MRI) to rule out structural injuries
While imaging scans often appear normal in PCS patients, they are used to exclude more serious conditions.
Treatment Options for Post-Concussion Syndrome
PCS treatment focuses on reducing symptoms and improving daily functioning. Common treatments include:
Medical treatment
- Medications for headaches or mood disorders
- Sleep regulation strategies
- Pain management
Rehabilitation
- Cognitive therapy
- Physical therapy
- Vestibular therapy for dizziness
- Vision therapy
- Balance training
Mental health care
- Cognitive-behavioral therapy (CBT)
- Counseling for anxiety, depression, or PTSD
Lifestyle modifications
- Rest and gradual return to normal activity
- Reduced screen time
- Controlled exercise programs
Many patients improve significantly with structured, multidisciplinary care.
Can Post-Concussion Syndrome Be Permanent?
PCS is usually temporary, but a small percentage of patients experience long-term or chronic symptoms. With proper medical intervention, most people see meaningful improvement over time.
When Is PCS Caused by Negligence?
PCS may be linked to a preventable injury caused by another person’s carelessness, such as:
- A distracted or reckless driver
- A negligent truck operator
- A property owner who failed to fix a hazard
- An employer who ignored known safety risks
When negligence causes a concussion that develops into PCS, victims may have the right to pursue compensation for medical bills, lost income, pain, emotional distress, and long-term care.
FAQ: Post-Concussion Syndrome ICD‑10 & PCS
What is the ICD-10 code for post-concussion syndrome?
The ICD‑10 code is F07.81, used to document PCS in medical and insurance records.
What symptoms qualify as post-concussion syndrome?
Persistent headaches, dizziness, sensory sensitivity, cognitive problems, fatigue, and emotional changes lasting weeks or months after a concussion.
Can PCS develop even after a mild concussion?
Yes. Even mild TBIs can lead to long-term symptoms.
How long does PCS last?
PCS lasts anywhere from a few months to several years, depending on the injury and individual circumstances.
Do I need a lawyer for PCS caused by an accident?
If another party’s negligence caused your injury, a personal injury lawyer can help you pursue compensation for economic and non-economic losses.
