Psoriasis — VA Disability Rating Criteria (DC 7816)

Diagnostic Code 7816 · 38 CFR §4.118

What Is It?

Psoriasis is a chronic immune-mediated disease that drives skin cells to turn over far faster than the body can shed them, building the thick, silvery, sharply bordered plaques that crack, bleed and itch. It favors the elbows, knees, scalp, navel and gluteal cleft, and it also attacks the nails as pitting, thickening and separation from the nail bed. It is systemic rather than cosmetic: up to a third of people with psoriasis develop psoriatic arthritis, and the disease carries recognized associations with cardiovascular disease, metabolic syndrome and depression. Veterans commonly see it begin or worsen in service, and the recognized triggers line up closely with military life — physical trauma to the skin producing new plaques at the site of injury, which dermatology calls the Koebner phenomenon, streptococcal infection, sustained psychological stress, certain medications including beta blockers, lithium and antimalarials, and abrupt withdrawal of systemic steroids. One structural point governs the whole claim. DC 7816 has no rating criteria of its own. The code reads "Evaluate under the General Rating Formula for the Skin" — the shared formula that also governs dermatitis and eczema at DC 7806 and several other codes — so the rating is set by that formula and by nothing specific to psoriasis.

Rating Criteria

Evidence Needed

The formula offers two independent routes to every level, joined by "or", and the strongest files build both. The first route is extent: a dermatologist's estimate of the percentage of total body surface area affected and, separately, the percentage of EXPOSED area affected, recorded during a typical flare rather than during remission. Those are two different numbers and the higher one governs, which matters for the veteran whose disease is confined to the scalp, face and hands. Ask for both to be written down; "moderate involvement" is not a percentage and cannot be scored. The second route is systemic therapy, and it is the route most veterans are under-rated on, because the formula's list is far broader than most people assume: corticosteroids, phototherapy, retinoids, biologics, photochemotherapy, PUVA, or other immunosuppressive drugs. Narrowband UVB light therapy counts. Acitretin counts. Adalimumab, etanercept, ustekinumab, secukinumab and the rest of the biologics count. Methotrexate and cyclosporine count. What decides the level on this route is DURATION over the past 12 months — under 6 weeks is 10 percent, 6 weeks or more but not constant is 30 percent, constant or near-constant is 60 percent — so the evidence is a pharmacy record with dispensing dates, an infusion or injection log, or a phototherapy attendance schedule, not a statement that you are "on a biologic." Add dated photographs from flares, the dermatology treatment history, and any documentation of nail or scalp involvement.

C&P Exam Tips

Schedule the examination during a flare if you have any control over the timing, and if you cannot, bring dated photographs from your worst recent weeks and say plainly that the appointment does not represent your typical state. Ask the examiner to record two separate figures — percentage of total body surface area and percentage of exposed area — because the DBQ asks for both and the higher one drives the rating. The other half of the examination is the medication history, and it is the half veterans most often leave on the table. Bring dispensing dates, not just drug names, because the formula is scored on how many weeks of the past 12 months you were on systemic therapy. Say explicitly if you are receiving phototherapy: narrowband UVB is systemic therapy under this formula, it appears in the regulation by name, and a veteran who reports "just light treatments" can be scored as though they were on topicals alone. The same goes for oral retinoids such as acitretin. If you have joint pain, stiffness that is worse in the morning, swollen fingers or toes, or nail changes, raise them at this examination and ask for a rheumatology referral — the Note to DC 7816 directs that psoriatic arthritis and other clinical manifestations be rated separately, and the skin examiner will not do it for you.

How to File

File under DC 7816 with dermatology records, the medication history with dates, phototherapy attendance records where applicable, and photographs from flares. Where the disease began in service, the service treatment records carry it directly; where it began afterwards, the routes are aggravation of a pre-existing condition, onset traceable to a documented in-service trigger such as skin trauma or streptococcal infection, or secondary service connection from a service-connected condition or its medication. Claim the complications separately, because the regulation tells the VA to rate them that way: the Note to DC 7816 directs that complications such as psoriatic arthritis and other clinical manifestations — for example oral mucosa and nails — be rated separately under the appropriate diagnostic code. Psoriatic arthritis in particular is a distinct claim with its own evaluation and is routinely left unfiled by veterans who assume the skin rating covers it. Note also that 38 CFR 4.118 provides for evaluating skin conditions as disfigurement of the head, face or neck under DC 7800, or as scars, depending on the predominant disability, where that produces the more accurate picture.

Common Mistakes

The most expensive mistake is a narrow reading of "systemic therapy." Veterans read the phrase, think of prednisone or methotrexate, and conclude they do not qualify — while attending narrowband UVB three times a week, which the General Rating Formula lists by name as phototherapy, or taking acitretin, which it lists as a retinoid. The formula's list is corticosteroids, phototherapy, retinoids, biologics, photochemotherapy, PUVA, or other immunosuppressive drugs, and any of them counts. The second mistake is being examined in remission and letting the report stand as the picture of the disease. Psoriasis waxes and wanes; 38 CFR 4.1 and 4.2 require the evaluation to reflect the disability over time, and photographs plus a clear treatment record are how you establish it. The third is accepting an examination that records one percentage instead of two — total body surface area and exposed area are scored separately and the higher governs. The fourth is documenting the drug without documenting the duration, when duration is what separates 10 from 30 from 60 percent. The fifth, and the one that costs the most across a lifetime, is never claiming psoriatic arthritis. It affects a large minority of people with psoriasis, it is progressive and erosive if untreated, the regulation expressly directs that it be rated separately, and it needs a rheumatology diagnosis to get onto the record.

Frequently Asked Questions

Does DC 7816 have its own rating criteria?

No. The code reads "Evaluate under the General Rating Formula for the Skin." That shared formula governs several skin codes, including DC 7806 for dermatitis and eczema, and it sets four levels — 0, 10, 30 and 60 percent — on either the percentage of body area affected or the amount of systemic therapy required over the past 12 months. Knowing this is useful in practice: it means nothing about the rating is psoriasis-specific, and it means the case law and adjudication practice built around DC 7806 applies to your claim too.

Does phototherapy count as systemic therapy?

Yes. The General Rating Formula lists phototherapy by name, alongside corticosteroids, retinoids, biologics, photochemotherapy, PUVA and other immunosuppressive drugs. This is the single most under-used fact on this page. A veteran attending narrowband UVB sessions who reports them as "light treatments" rather than as phototherapy can be scored as though on topicals alone, which is 0 percent. Make sure the attendance record is in the file and the term is used.

Do biologics get me to 60 percent?

Not automatically — the level depends on duration over the past 12 months, not on the class of drug. Systemic therapy for less than 6 weeks in the year is 10 percent, 6 weeks or more but not constant is 30 percent, and constant or near-constant is 60 percent. Because biologics for psoriasis are maintenance therapy given on a continuing schedule, a veteran on one throughout the year is typically describing constant or near-constant systemic therapy. What proves it is the dispensing or infusion record showing the year covered, not the prescription alone.

How does the VA count exposed areas?

Exposed areas are the parts of the body ordinarily visible — head, face, neck and hands. The formula scores total body surface area and exposed area separately at each level, and the higher of the two governs. That matters most for scalp, facial and hand psoriasis, which can occupy a small share of the whole body while covering a large share of the exposed area. Ask for both percentages to be recorded at the examination.

Should I file for psoriatic arthritis separately?

Yes, and the regulation says so. The Note to DC 7816 directs that complications such as psoriatic arthritis and other clinical manifestations — for example oral mucosa and nails — be rated separately under the appropriate diagnostic code. Psoriatic arthritis develops in a substantial minority of people with psoriasis, often years after the skin disease, and it can cause permanent joint damage if it goes untreated. It needs its own diagnosis, usually from rheumatology, and its own claim. A skin rating does not compensate it.

Can psoriasis be connected to service if it started afterwards?

It can, on several routes. Where it began in service the treatment records establish it directly. Where a pre-existing case worsened beyond its natural progression in service, that is aggravation. Where it began afterwards, the argument runs through a documented in-service trigger — skin trauma producing plaques at the injury site, streptococcal infection, or sustained stress — supported by a medical opinion, or through secondary service connection where a service-connected condition or its medication precipitated it. Beta blockers, lithium and antimalarials are recognized medication triggers, which makes the secondary route concrete where one of them was prescribed for a service-connected disability.
