TBI CLINICAL GUIDE

TBI and concussion after a Florida car accident.

Traumatic brain injury encompasses a spectrum from brief concussion to severe structural damage. In Florida motor vehicle accidents, mild TBI (concussion) is the most common presentation and the most frequently under-documented. Attorneys who understand Glasgow Coma Scale grading, post-concussion syndrome criteria, and the clinical workup pathway are equipped to build the medical record that supports damages from neurologic injury.

The clinical spectrum of TBI in Florida MVA cases.

Traumatic brain injury (TBI) is defined as an alteration in brain function or evidence of brain pathology caused by an external force. In motor vehicle accidents, the mechanism is typically a combination of direct head impact (against steering wheel, window, or headrest) and inertial forces that cause the brain to move within the skull without direct contact (coup-contrecoup). Both mechanisms can produce concussion without visible structural injury on standard CT.

The Glasgow Coma Scale (GCS) is the primary acute severity classification tool. GCS scores motor response (1-6), verbal response (1-5), and eye opening (1-4), for a maximum of 15. Mild TBI is defined as GCS 13-15 with loss of consciousness less than 30 minutes, post-traumatic amnesia less than 24 hours, and normal CT. Moderate TBI is GCS 9-12. Severe TBI is GCS 3-8. Most Florida MVA TBI cases are mild (mTBI); however, mild does not mean inconsequential. Long-term post-concussion symptoms are more common after mTBI than is generally appreciated.

CT head in the acute setting is the appropriate first study to rule out intracranial hemorrhage (epidural hematoma, subdural hematoma, subarachnoid hemorrhage, intraparenchymal contusion). A normal CT does not rule out TBI; it rules out the acute structural emergencies that require neurosurgical intervention. Standard CT has poor sensitivity for axonal injury, small contusions, and the microstructural changes that produce post-concussion syndrome.

MRI is substantially more sensitive than CT for parenchymal contusion, diffuse axonal injury (DAI), and small foci of hemorrhage (microbleeds visible on gradient echo or susceptibility-weighted sequences). Subacute MRI (ordered 2-4 weeks after the accident when symptoms persist) is the appropriate next imaging step when the clinical picture supports TBI but CT was normal. Advanced MRI techniques including diffusion tensor imaging (DTI) can detect white matter tract injury not visible on conventional sequences, though DTI findings are subject to ongoing evidentiary debate.

Neuropsychological testing is the cornerstone of functional TBI assessment. It quantifies deficits in attention, working memory, processing speed, executive function, and visuospatial skills that may not be apparent on examination or imaging. A neuropsychologist administers a battery of standardized tests and compares performance to normative databases adjusted for age, education, and premorbid function. In PI litigation, neuropsych results provide objective, quantitative evidence of cognitive injury that correlates with the patient's complaints of difficulty concentrating, memory lapses, and occupational impairment.

The TBI evaluation and treatment pathway in Florida PI cases.

  1. Day 0

    Emergency evaluation and GCS scoring

    ED evaluation includes GCS scoring, neurologic examination, and CT head to rule out hemorrhage and structural injury. Post-traumatic amnesia duration is established by history. The ED record's GCS score, CT result, and any notation of loss of consciousness or confusion is the foundational TBI document in every PI case. Attorneys should always obtain the full ED record, not just the discharge summary.

  2. Days 1-14

    Specialist intake within the PIP window

    A neurologist or PI-experienced physician evaluates the patient within the 14-day PIP window. The evaluation documents: current symptoms (headache, dizziness, cognitive complaints, sleep disturbance, mood changes), neurologic examination, and a formal TBI grading. The provider determines whether EMC certification is appropriate for the $10,000 PIP tier. Most mTBI with ongoing symptoms qualifies for EMC.

  3. Weeks 2-8

    Symptom-specific workup

    Based on the symptom profile, the neurologist orders targeted studies: MRI brain (for persistent headache, cognitive complaints, or abnormal exam); audiometric and vestibular testing (for vertigo, balance, or hearing complaints); neuropsychological testing (for memory, attention, or cognitive complaints); ophthalmology or neuro-ophthalmology referral (for visual disturbance).

  4. Weeks 4-12

    Neuropsychological testing

    Formal neuropsychological evaluation typically takes 4-8 hours and includes standardized tests for attention, memory, processing speed, executive function, language, and visuospatial abilities. A psychologist interprets results in the context of the patient's premorbid baseline and current symptom profile. The report provides the most objective quantitative evidence of cognitive deficit available in a TBI case.

  5. Ongoing

    Vestibular rehabilitation

    Dizziness and balance complaints affect 30-40 percent of mTBI patients. Videonystagmography (VNG) and rotary chair testing identify benign paroxysmal positional vertigo (BPPV), semicircular canal dysfunction, or central vestibular pathology. Vestibular physical therapy is an evidence-based treatment. Documentation of vestibular findings and treatment supports functional limitation claims.

  6. Month 3+

    Post-concussion syndrome diagnosis and LOP care

    Symptoms persisting beyond 3 months in an mTBI patient meet criteria for Post-Concussion Syndrome (ICD-10 F07.81). This diagnosis triggers a treatment pathway including cognitive rehabilitation, vestibular therapy, and possible psychiatric or neuropsychiatric co-management. After PIP exhausts, LOP arrangements fund continued neurologic care under the §768.0427 framework.

PIP and LOP billing for TBI neurologic care in Florida.

Neurologic evaluation and TBI management are PIP-covered services under §627.736 when medically necessary. Initial neurologic evaluation (CPT 99205, new patient; CPT 99215, established complex), neuropsychological testing (CPT 96116-96138), MRI brain (CPT 70553 with and without contrast), and vestibular testing (CPT 92540-92548) are all reimbursable at 80 percent of 200 percent of the Medicare fee schedule. Neuropsychological testing is expensive (may exceed $3,000-5,000) and often runs against PIP limits, making EMC certification critical for TBI cases.

The most important PIP billing action in a TBI case is early EMC certification by the treating neurologist or evaluating physician. A mTBI patient with persistent headache, cognitive complaints, and sleep disturbance following a motor vehicle accident meets the statutory definition of Emergency Medical Condition in most clinical presentations. Without the EMC, the $2,500 PIP default cap will be consumed by the initial evaluation and first few treatment visits, leaving neuropsychological testing, imaging, and vestibular evaluation unfunded.

Under §768.0427, LOP-billed neurologic and neuropsychological services are capped at 120 percent of Medicare for uninsured patients at trial. Neuropsychological testing at $4,000-6,000 billed LOP will be reduced to approximately 120 percent of the Medicare allowable. For CPT 96132 (neuropsychological testing, first hour), the Medicare allowable is approximately $150-200; each additional hour (CPT 96133) is similar. Providers and attorneys should factor this framework into LOP charge structures.

What attorneys need in TBI medical records for a Florida PI case.

GCS score and LOC duration from ED records

The ED record is the evidentiary anchor for every TBI claim. It should contain a GCS score (ideally serial scores), notation of loss of consciousness and duration, post-traumatic amnesia, and the CT head result. If the patient was transported by EMS, the EMS run sheet also contains a field GCS.

Neuropsychological test results

The full neuropsychological report, not just the summary, should be obtained. It provides the test battery administered, raw scores, percentile ranks, and normative comparisons. Defense neuropsychologists will scrutinize validity measures (embedded performance validity tests). A report that addresses validity measures directly is more litigation-resistant.

Functional impairment documentation

The treating neurologist should document how cognitive deficits affect work performance, daily activities, and social functioning at each visit. Standardized functional scales (PCSS, RPQ) provide quantitative symptom burden tracking. This documentation supports lost wage and quality-of-life damages beyond medical expenses.

Causation opinion referencing the accident

The neurologist's record should contain a causation statement attributing the TBI 'within reasonable medical probability' to the date-of-loss motor vehicle accident. TBI causation is frequently contested by defense experts. The treating neurologist's causation opinion, supported by clinical findings and test results, is essential for the attorney's damages narrative.

Frequently asked questions.

Can you have a TBI if the ED CT scan was normal?

Yes. Standard CT is insensitive to the microstructural changes that produce concussion symptoms. CT primarily detects macrostructural injuries (hemorrhage, large contusions) that require acute surgical management. A normal CT rules out neurosurgical emergencies, not TBI. Persistent symptoms after a normal CT should be evaluated with MRI and neuropsychological testing.

What is the Glasgow Coma Scale and how is it used in TBI grading?

The GCS scores eye opening (1-4), verbal response (1-5), and motor response (1-6) for a maximum of 15. Mild TBI is GCS 13-15; moderate is 9-12; severe is 3-8. The GCS score recorded at the accident scene or in the ED is the standard acute severity measure. A GCS of 15 does not exclude TBI; many concussion patients present with full consciousness but impaired cognition.

How is post-concussion syndrome diagnosed?

Post-concussion syndrome (ICD-10 F07.81) is diagnosed when three or more post-concussion symptoms persist for at least three months after a documented mTBI. Symptom clusters include cognitive (memory, concentration), somatic (headache, dizziness, fatigue, sleep disturbance), and affective (irritability, anxiety, depression). Diagnosis requires documented mTBI and exclusion of other causes for the symptom complex.

Is neuropsychological testing covered by Florida PIP?

Yes, when medically necessary for TBI evaluation. Neuropsychological testing CPT codes (96116, 96132, 96133, 96136, 96137) are covered at 80 percent of 200 percent of the Medicare fee schedule under §627.736. Given that a full neuropsychological evaluation may cost $3,000-6,000, EMC certification to access the $10,000 PIP tier is essential for TBI cases requiring this evaluation.

What is vestibular therapy and when is it indicated after a concussion?

Vestibular physical therapy treats dizziness, balance impairment, and visual-vestibular mismatch caused by inner ear or central vestibular dysfunction after mTBI. It includes canalith repositioning for BPPV, gaze stabilization exercises, and balance retraining. Indication is persistent dizziness, vertigo, or balance complaints after concussion. VNG testing establishes the baseline before therapy. Most patients with post-traumatic vestibular dysfunction show measurable improvement with 6-12 weeks of targeted vestibular PT.
