Carpal Tunnel Syndrome
- Carpal tunnel is rated differently for dominant (major) vs. non-dominant (minor) hand at moderate and higher severity levels.
- EMG/nerve conduction studies are the gold standard for objective documentation of median nerve compression.
- Common in military occupations involving repetitive hand motions, mechanics, clerks, communications operators, and riflemen.
- Can be claimed as secondary to diabetes (diabetic neuropathy affecting the median nerve) or to wrist/hand injuries.
- Carpal tunnel release surgery does not end the claim, residual symptoms after surgery are still ratable.

Overview
Carpal tunnel syndrome is a neurological condition caused by compression of the median nerve as it passes through the carpal tunnel in the wrist. It produces numbness, tingling, weakness, and pain in the hand and fingers, particularly the thumb, index, middle, and ring fingers. It is rated under Diagnostic Code 8515 (paralysis of the median nerve).
The VA rates carpal tunnel differently depending on whether it affects the dominant (major) or non-dominant (minor) hand. For complete paralysis, the major hand receives 70% and the minor receives 60%. At the severe level, the split is 50%/40%, moderate is 30%/20%, and mild is 10% for either hand. This dominant/non-dominant distinction is significant because it affects the final rating.
Carpal tunnel syndrome is common among veterans whose military service involved repetitive hand and wrist motions: mechanics, administrative clerks, communications operators, riflemen, and other MOSs with sustained grip or vibration exposure. It may also develop secondary to conditions that cause swelling or inflammation in the wrist, such as diabetes or rheumatoid arthritis.
Rating Criteria
| Rating | Criteria |
|---|---|
| 10% | Mild incomplete paralysis of the median nerve (either hand). Intermittent numbness and tingling with preserved grip strength. |
| 20% | Moderate incomplete paralysis of the median nerve (minor/non-dominant hand). Regular numbness, decreased grip strength, and difficulty with fine motor tasks. |
| 30% | Moderate incomplete paralysis of the median nerve (major/dominant hand). Regular numbness, decreased grip strength, and difficulty with fine motor tasks. |
| 40% | Severe incomplete paralysis of the median nerve (minor/non-dominant hand). Significant weakness, thenar atrophy, and marked impairment of hand function. |
| 50% | Severe incomplete paralysis of the median nerve (major/dominant hand). Significant weakness, thenar atrophy, and marked impairment of hand function. |
| 60% | Complete paralysis of the median nerve (minor/non-dominant hand). Inability to make a fist, thumb opposition lost, hand inclined to ulnar side. |
| 70% | Complete paralysis of the median nerve (major/dominant hand). Inability to make a fist, thumb opposition lost, hand inclined to ulnar side. |

- 60%
Complete paralysis of the median nerve (minor/non-dominant hand). Inability to make a fist, thumb opposition lost, hand inclined to ulnar side.
- 70%
Complete paralysis of the median nerve (major/dominant hand). Inability to make a fist, thumb opposition lost, hand inclined to ulnar side.
These criteria describe how a VA Compensation & Pension examiner evaluates the condition during a rating exam. They are not a self-test. For mental health conditions under 38 CFR 4.130, a diagnosis must be made by a qualified clinician under DSM-5. Actual ratings depend on the totality of evidence reviewed by the VA.
Evidence Checklist
Required
EMG/nerve conduction study
Electrodiagnostic testing documenting median nerve compression at the wrist, including the severity of nerve dysfunction.
Clinical examination
Physical examination including Phalen's test, Tinel's sign, and grip strength measurements documenting the severity of nerve involvement.
Recommended
Surgical records
If carpal tunnel release surgery was performed, operative reports and post-surgical follow-up documenting residual symptoms.
Occupational history
Documentation of military duties involving repetitive hand/wrist movements, vibration exposure, or sustained gripping.
Helpful
Functional impact statement
A personal statement describing how hand weakness and numbness affect daily tasks such as gripping, writing, and manipulating objects.
Secondary Conditions
These conditions may be claimed as secondary to Carpal Tunnel Syndrome. A nexus is the medical link between a service-connected condition and a related condition. Nexus strength indicates the level of established medical evidence supporting that connection.
Depression
DC 9434, Typical range: 0%, 10%, 30%, 50%
Opposite Hand Carpal Tunnel
DC 8515, Typical range: 10%, 20%, 30%
Thenar Atrophy / Grip Weakness
DC 8515, Typical range: 10%, 20%, 30%, 50%
