| 0% | § 4.31 Zero percent evaluations. In every instance where the schedule does not provide a zero percent evaluation for a diagnostic code, a zero percent evaluation shall be assigned when the requirements for a compensable evaluation are not met. | Your psoriatic arthritis is service connected and documented, but at the time of examination it is neither in an active exacerbation nor leaving limitation of motion that any joint code compensates. The lowest compensable rung on this ladder is 10 percent. A zero percent rating pays nothing now, but it establishes service connection and fixes the effective date any later increase runs from. |
|---|
What supports this level- Documented diagnosis of psoriatic arthritis by rheumatologist
- Examination finding no active exacerbation and no compensable limitation of motion
- Range of motion measured and recorded for every affected joint, even when normal
- Continued rheumatology and dermatology records, so a later increase has a documented history
|
| 10% | Note (2): With the types of arthritis, diagnostic codes 5004 through 5009, rate the acute phase under diagnostic code 5002; rate any chronic residuals under diagnostic code 5003. Degenerative arthritis established by X-ray findings will be rated on the basis of limitation of motion under the appropriate diagnostic codes for the specific joint or joints involved (DC 5200 etc.). When however, the limitation of motion of the specific joint or joints involved is noncompensable under the appropriate diagnostic codes, a rating of 10 pct is for application for each such major joint or group of minor joints affected by limitation of motion, to be combined, not added under diagnostic code 5003. Limitation of motion must be objectively confirmed by findings such as swelling, muscle spasm, or satisfactory evidence of painful motion. | Your psoriatic arthritis is not in an active flare, but it has left chronic residuals — limitation of motion of an affected joint that is objectively confirmed by swelling, muscle spasm, or painful motion, yet is not severe enough to be compensable under the diagnostic code for that joint. DC 5009 Note (2) sends chronic residuals to DC 5003, which pays 10 percent for each such major joint or group of minor joints. |
|---|
What supports this level- Documented diagnosis of psoriatic arthritis by rheumatologist
- Confirmed psoriasis diagnosis by dermatologist
- Limitation of motion that is noncompensable under the code for the affected joint
- Painful motion, swelling, or muscle spasm objectively confirmed on examination
- Disease not in an active flare at the time of examination
|
| 20% | One or two exacerbations a year in a well-established diagnosis. | You have psoriatic arthritis with one or two joints affected and occasional flare-ups, in a well-established diagnosis. You have pain and stiffness, but you can still perform most daily activities with medication. |
|---|
What supports this level- Documented diagnosis of psoriatic arthritis by rheumatologist
- Confirmed psoriasis diagnosis by dermatologist
- One or two documented exacerbations per year
- Well-established diagnosis in the treatment record
- Inflammatory markers (ESR, CRP) elevated during flares
- Joint swelling and tenderness on examination
- Imaging showing joint involvement (erosions, joint space narrowing)
|
| 40% | Symptom combinations productive of definite impairment of health objectively supported by examination findings or incapacitating exacerbations occurring 3 or more times a year. | You have psoriatic arthritis with multiple joints affected and frequent flare-ups. Your symptoms significantly limit your physical activities and may require stronger medications such as biologics. |
|---|
What supports this level- Multiple joints with active inflammation
- Dactylitis (sausage digits) documented
- Enthesitis (tendon insertion inflammation) documented
- Incapacitating exacerbations 3+ times per year
- Biologic or DMARD therapy required
|
| 60% | Less than criteria for 100% but with weight loss and anemia productive of severe impairment of health or severely incapacitating exacerbations occurring 4 or more times a year or a lesser number over prolonged periods. | You have psoriatic arthritis with severe joint damage, significant skin involvement, and constitutional symptoms like fatigue and weight loss. You cannot perform most physical work. |
|---|
What supports this level- Joint destruction visible on X-ray or MRI
- Severe psoriasis with extensive skin involvement
- Constitutional symptoms (fatigue, weight loss, anemia)
- Nail dystrophy and joint deformities
- Unable to perform most physical activities
|
| 100% | With constitutional manifestations associated with active joint involvement, totally incapacitating. | You have psoriatic arthritis with completely disabling joint disease and widespread skin involvement. You are unable to work or care for yourself independently. |
|---|
What supports this level- Totally incapacitating joint involvement
- Arthritis mutilans (severe joint destruction)
- Unable to perform activities of daily living
- Continuous biologic therapy with poor response
- Documented total occupational impairment
