Erythema Multiforme and Toxic Epidermal Necrolysis — VA Rating (DC 7827)
Diagnostic Code 7827 · 38 CFR §4.118
What Is It?
Erythema multiforme is an immune-mediated reaction that produces the characteristic target or bull's-eye lesions on the skin, often with painful erosions of the mouth, eyes, and genitals. Its severe forms — Stevens-Johnson syndrome and toxic epidermal necrolysis — are dermatologic emergencies in which the skin blisters and sheds in sheets. The usual triggers are medications (sulfonamides, anticonvulsants, allopurinol, NSAIDs) and infections, herpes simplex and mycoplasma above all, which is why service-connection arguments so often run through a drug prescribed for another service-connected condition or an infection acquired on deployment. DC 7827 does not use the body-surface-area formula that most skin codes use. It rates by episode count and by function: how many times in the past twelve months you had mucosal, palmar, or plantar involvement, whether that involvement impaired chewing, use of the hands, or walking, and what therapy was required to control it. A note under this code broadens the definition of systemic therapy to include antihistamines and sympathomimetics as well as immunosuppressives — a meaningfully lower bar than the one in §4.118(a).
Rating Criteria
| Rating | Criteria |
|---|---|
| 60% | Recurrent mucosal, palmar, or plantar involvement impairing mastication, use of hands, or ambulation, occurring four or more times over the past 12-month period despite ongoing immunosuppressive therapy. This is the maximum schedular evaluation under DC 7827; alternatively, rate as disfigurement of the head, face, or neck (DC 7800) or scars (DC 7801, 7802, 7804, or 7805), depending on the predominant disability. |
| 30% | Recurrent mucosal, palmar, or plantar involvement not impairing mastication, use of hands, or ambulation, occurring four or more times over the past 12-month period, and requiring intermittent systemic therapy. |
| 10% | One to three episodes of mucosal, palmar, or plantar involvement not impairing mastication, use of hands, or ambulation over the past 12-month period, and requiring intermittent systemic therapy; or, without recurrent episodes but requiring continuous systemic medication for control. |
Evidence Needed
This claim is built on a countable episode history, so the record needs dates. Emergency department visits, urgent care notes, hospital admissions, and dermatology visits that each document a discrete episode are the backbone; four documented episodes in twelve months is the line between 10 percent and 30 percent. A biopsy confirming erythema multiforme, Stevens-Johnson syndrome, or toxic epidermal necrolysis anchors the diagnosis. Photographs of target lesions and of mucosal involvement during an episode are valuable because the findings resolve completely between attacks. Medication records establish both the trigger and the therapy — and note that under this code antihistamines and sympathomimetics count as systemic therapy, not just immunosuppressives. If episodes impair chewing, hand use, or walking, that functional detail has to appear in the record in those terms, because it is the difference between 30 percent and 60 percent.
C&P Exam Tips
You will very likely be examined between episodes, when your skin looks normal — that is the nature of this condition and it is not a reason to lose the claim. Bring a dated episode log listing every attack in the past twelve months with what was involved (mouth, palms, soles, eyes), how long it lasted, what treatment you needed, and what you could not do. Bring photographs from the episodes themselves. State plainly whether attacks have impaired your ability to chew, to use your hands, or to walk, because the examiner will not infer it. Bring the complete medication list, including antihistamines. If prior episodes left scarring, eye damage, or nail loss, ask that those residuals be examined too — they are separately ratable under the scar, eye, and skin codes.
How to File
File on VA Form 21-526EZ as erythema multiforme, Stevens-Johnson syndrome, or toxic epidermal necrolysis under DC 7827. Attach the biopsy or diagnosing dermatology note, a dated episode log, photographs, hospital and emergency records, and the full medication history. If the trigger was a medication prescribed to treat a service-connected condition, file it as a secondary claim and name that condition and the drug. Claim residual scarring under DC 7800 through 7805 and any eye involvement under the appropriate eye code as separate issues in the same claim.
Common Mistakes
The largest mistake is assuming the body-surface-area rules apply. They do not — DC 7827 counts episodes and looks at function, and a veteran who documents skin coverage instead of attack frequency has documented the wrong thing. The second mistake is not writing down episodes as they happen; twelve months later the count is a memory, and the claim turns on whether it was three or four. The third is leaving the functional impairment unstated. "Painful mouth sores" reads as a 30 percent picture; "could not eat solid food for nine days" reads as impaired mastication, which is the 60 percent criterion. The fourth is missing the secondary pathway when the trigger drug was prescribed for a service-connected disability — that is a clean, well-recognized route to service connection that veterans routinely never claim.
Frequently Asked Questions
Is Stevens-Johnson syndrome rated under DC 7827?
Yes. The code heading covers erythema multiforme and toxic epidermal necrolysis, and Stevens-Johnson syndrome sits on the same disease spectrum between the two. All three are rated on the same episode-and-function criteria. Severe cases usually generate substantial residuals — scarring, eye damage, nail loss, chronic dry eye — and those residuals are separately ratable under their own codes.
How does the VA count an "episode"?
As a discrete flare of mucosal, palmar, or plantar involvement documented in the medical record. Four or more in a twelve-month period is the threshold for 30 percent, and four or more that impair chewing, hand use, or walking despite ongoing immunosuppressive therapy is the threshold for 60 percent. Contemporaneous documentation is what makes an episode countable, which is why a dated log plus the visit records matters more here than in almost any other skin claim.
Do antihistamines count as systemic therapy for this code?
Yes. A note under DC 7827 provides that for the purposes of this diagnostic code only, systemic therapy may consist of immunosuppressives, antihistamines, or sympathomimetics. That is broader than the general definition in 38 CFR §4.118(a), and it means a veteran maintained on continuous oral antihistamines can meet the 10 percent criterion on the "requiring continuous systemic medication for control" path even without recurrent episodes.
Can I get service connection if a prescribed drug caused it?
Often yes, on a secondary basis. If the medication was prescribed to treat a service-connected condition and it triggered erythema multiforme, the reaction is a consequence of the service-connected disability under 38 CFR §3.310. Name the primary condition, the drug, the prescribing facility, and the date, and get a medical opinion linking the reaction to the medication.
What about scarring left behind after an episode?
Rate it separately. DC 7827 compensates the recurrent disease process; the permanent scarring it leaves is a different disabling effect and is rated under DC 7800 for the head, face, or neck, DC 7801 or 7802 by area elsewhere, and DC 7804 if the scars are painful or unstable. Eye involvement — corneal scarring, chronic dry eye, symblepharon — is rated under the eye codes and is common after Stevens-Johnson syndrome.
