9 of 9 conditions
Lumbosacral or Cervical Strain
A strain or sprain of the muscles and ligaments supporting the neck or lower back, causing pain, stiffness, and reduced range of motion — often from lifting, impact, or repetitive strain during service.
Read the condition guidePreview the guide
Evidence covered in the guide
- C&P or orthopedic exam showing measured loss of range of motion, muscle spasm, or guarding
- Service treatment records documenting the in-service injury, incident, or repetitive strain
- Buddy statements or personnel records corroborating the in-service event (e.g., heavy lifting, vehicle accident, parachute jumps)
Degenerative Arthritis of the Spine
Wear and tear in the spine causing stiffness, pain, or nerve issues.
Read the condition guidePreview the guide
Evidence covered in the guide
- Range of motion tests from VA or ortho
- MRI or X-ray showing degenerative disc disease
- Doctor notes on back pain frequency
Knee, Other Impairment of
This diagnostic code covers knee instability — the knee buckling, giving out, or shifting out of place — separately from pain or arthritis. Since the 2021 rewrite it rates two named things: recurrent subluxation or instability after a ligament sprain or tear, and instability of the kneecap (the patellofemoral complex) after surgical repair. The tier you land on depends less on how bad the instability feels than on what a medical provider has prescribed for it — a brace, a walking aid, both, or neither.

Evidence covered in the guide
- The prescription itself — the note or order from a medical provider prescribing a brace, cane, crutches, or a walker for walking. Since 2021 this is the single fact that separates the three tiers, and buying a brace over the counter is not the same thing.
- An orthopedic evaluation documenting persistent instability with stability testing (Lachman, anterior drawer, pivot shift), and stating whether a ligament tear is complete or incomplete.
- Operative reports where a ligament or the patellofemoral complex was repaired, plus follow-up notes on whether the repair held — a failed repair rates higher than a successful one on the same prescription.
Tinnitus
Tinnitus means you hear ringing, buzzing, or hissing in your ears even when there’s no sound.
Read the condition guidePreview the guide
Evidence covered in the guide
- Consistent reports of tinnitus in VA exams
- History of military noise exposure (e.g., flight line, artillery)
- C&P exam confirmation
Residuals of Traumatic Brain Injury (TBI)
TBI results from head trauma and can cause lasting issues with memory, mood, sleep, and decision-making.

Evidence covered in the guide
- VA TBI screening and exam results
- Neurologist evaluations
- Neurocognitive tests (e.g., memory, attention)
Post-Traumatic Stress Disorder (PTSD)
PTSD is a mental health issue caused by a traumatic event, leading to flashbacks, anxiety, or nightmares.
Read the condition guidePreview the guide
Evidence covered in the guide
- Formal PTSD diagnosis from a VA or private psychiatrist
- C&P exam results showing PTSD symptoms
- Buddy statements confirming trauma or symptoms
Migraine
Severe recurring headaches that may include nausea, light sensitivity, and inability to function.
Read the condition guidePreview the guide
Evidence covered in the guide
- Neurology consult with detailed migraine history
- Headache diary showing frequency and impact
- Employer or family statements about missed work or functional episodes
Ankle, Limitation of Motion
Reduced ability to flex or extend the ankle, usually due to injury or arthritis.
Read the condition guidePreview the guide
Evidence covered in the guide
- An orthopedic exam specifically documenting range-of-motion measurements.
- X-rays or an MRI showing the underlying cause of the limitation.
Tenosynovitis
Tenosynovitis is inflammation of the sheath that surrounds a tendon, causing pain, swelling and catching on movement. Since February 7, 2021 DC 5024 has covered a wider family — the schedule titles it "Tenosynovitis, tendinitis, tendinosis or tendinopathy", so rotator cuff tendinitis, De Quervain's tenosynovitis, lateral epicondylitis, Achilles tendinopathy and trigger finger are all rated here. The code has no percentages of its own: it is rated as degenerative arthritis, on limitation of motion of the affected part.
Read the condition guidePreview the guide
Evidence covered in the guide
- Goniometer range-of-motion measurements, in degrees, for the joint the affected tendon crosses — this is the only thing DC 5024 rates.
- Examination findings recording objective painful motion, localized swelling along the tendon, or crepitus, which is the confirmation DC 5003 requires before the per-joint 10 percent can be assigned.
- Ultrasound or MRI showing tendon sheath thickening, tendinosis or a partial tear, plus injection, splinting, physical therapy or release-surgery records.
