Korea's disability registration system recognizes 16 distinct disability types, each defined by its own diagnostic criteria, assigned to a specific category of specialist physician, and reviewed centrally by the National Pension Service on the Ministry of Health and Welfare's behalf before a local government issues (or refuses) a disability registration card. A pancreatic disability category was added to the list effective July 1, 2026 — the first new type added in years, reflecting the Ministry's ongoing revisions to the underlying notice (보건복지부고시 제2025-228호). This office has represented applicants through first-time registration filings, the separate foreigner/overseas-Korean registration track, and the objection-and-appeal process that follows a denial — including citing reported administrative-appeal rulings and court decisions on how much weight a treating physician's diagnosis should carry against the pension service's file-based review.
Korean law divides disability into a physical category and a mental category, each split further into external and internal (physical) or developmental and psychiatric (mental) sub-groups:
Physical — external body function (6 types): 지체장애 (physical/limb disability — amputation, joint, functional-limb, spinal, or deformity-related), 뇌병변장애 (brain-lesion disability from stroke, cerebral palsy, or brain injury), 시각장애 (visual — acuity loss, visual-field defect, double vision), 청각장애 (hearing — hearing loss or balance dysfunction), 언어장애 (speech, voice, or language disability), and 안면장애 (facial disfigurement from scarring, depression, or thickening deformity).
Physical — internal organ function (7 types): 신장장애 (kidney — dialysis or transplant), 심장장애, 간장애 (liver), 호흡기장애 (respiratory), 장루·요루장애 (ostomy), 뇌전증장애 (epilepsy), and the newest addition, 췌장장애 (pancreatic — endocrine dysfunction).
Mental — developmental and psychiatric (3 types): 지적장애 (intellectual disability, IQ 70 or below), 자폐성장애 (autism spectrum), and 정신장애 (covering schizophrenia, schizoaffective disorder, bipolar disorder, recurrent depressive disorder, organic mental disorders from neurological damage, OCD, Tourette's, and narcolepsy).
The 2019 reform abolished the old Grade 1–6 system in favor of two bands: "severe" disability (formerly Grades 1–3) and "not severe" disability (formerly Grades 4–6). Every type's classification table below still maps to one of those two bands, not a numeric grade.
Each disability type is locked to a specific specialist category, and going to the wrong one wastes the application. A few examples pulled directly from the Ministry's diagnostic-institution table: amputation-type physical disability needs a physician with X-ray facilities; most other physical disabilities need rehabilitation medicine, orthopedics, neurosurgery, neurology, pediatrics (neurology subspecialty), or rheumatology; brain-lesion disability needs rehabilitation medicine, neurosurgery, neurology, or pediatric neurology; visual disability needs ophthalmology with visual-field and diplopia testing capability; hearing disability needs an ENT specialist with a soundproof audiometry booth; intellectual disability needs psychiatry, neurology, rehabilitation medicine, or pediatric neurology; autism needs psychiatry specifically; kidney disability for dialysis needs a physician who has treated the applicant for 3+ months (or, absent that, 1+ month with a confirmed 3-month dialysis record); epilepsy needs 6+ months of continuous treatment at a neurology, neurosurgery, psychiatry, or pediatric-neurology practice; and pancreatic disability needs an endocrinology-subspecialty internist or pediatrician who has treated the applicant continuously for 3+ months.
Timing rules matter as much as the specialist. Most physical disabilities can only be diagnosed once the underlying condition has "stabilized" — generally after 6 months to 2 years of treatment, except where stabilization is self-evident (limb amputation, spinal fusion, eye enucleation, total laryngectomy, congenital intellectual disability). Brain-lesion disability from stroke or injury needs 6+ months of treatment; Parkinson's needs a full year. Psychiatric disability needs 1–2 years of consistent treatment with no clear sign of improvement. Pancreatic disability specifically requires 6+ months of active multi-dose insulin therapy or insulin pump use with no improvement, documented by two C-peptide measurements at least 3 months apart within the last 6 months (or one measurement within 3 months for a re-assessment), each showing a fasting glucose of 140 mg/dL or higher alongside the qualifying C-peptide result.
Registration isn't always permanent for a given type, either. Several categories, including pancreatic disability, are re-assessed roughly every 2 years after the first determination — though after three consecutive re-assessments confirming the same disability, or after a procedure that makes the condition irreversible (a full pancreatectomy, for example), the type is exempted from further re-assessment. Applicants filing for a type subject to periodic re-assessment should plan for the next filing window rather than treat the first registration as final.
Filing goes through the applicant's local eup/myeon/dong administrative welfare center. The universal starting document is a "disability-severity assessment medical certificate" (장애정도심사용진단서) dated close to the filing date — issued only by a physician in the specialist category matched to the applicant's claimed disability type — plus type-specific supporting evidence:
Applications are normally filed by the individual, but a legal guardian, a designated caregiver, or someone holding the applicant's power of attorney can file on their behalf, and for a bedridden individual living alone, a public official can initiate the filing directly with the individual's consent.
Foreign residents can register as disabled in Korea, but eligibility is restricted to specific visa/status categories: F-5 permanent residents, F-6 marriage migrants, F-4 overseas Koreans with a domestic residence report, F-2 recognized refugees (effective since March 20, 2018) and designated "persons of special merit," and 재외국민 (Korean nationals registered as overseas residents). Each category files at a different jurisdiction: F-5 holders and Korean-national spouses file where they reside; F-4 holders file where their domestic residence is reported; 재외국민 file where their resident registration is on record; recognized refugees file where they reside.
The evidentiary rule is strict: medical records produced overseas are not accepted for a disability-severity assessment except where the disability is unmistakably permanent — limb amputation, deformity-type disability (dwarfism, a 5cm+ leg-length discrepancy), spinal fusion, congenital cerebral palsy, eye enucleation, an organ transplant (kidney, heart, lung, liver), or an irreversible ostomy. In those specific cases, a notarized Korean translation of the foreign surgical or treatment record can substitute for domestic treatment history, though supplementary documentation may still be requested. Registered foreign nationals also have their eligible status re-verified every 6 months, and registration can be revoked if their status lapses (for example, if they relocate abroad).
Workplace injuries are a recurring reason foreign workers end up filing this claim — an accident on the job leaves a permanent limb, hearing, or organ impairment, and once the visa status is one of the qualifying categories above, registering unlocks the same domestic support system a Korean national would receive. Because this office holds both a licensed immigration-affairs-agency registration and an 외국어번역행정사 (certified foreign-language translation) credential, it can handle the visa-status confirmation, the notarized translation of any qualifying overseas medical record, and the registration filing itself as one engagement rather than three separate ones.
An applicant who receives a "does not qualify" (미해당) notice has 90 days from the notice date to file a single objection (이의신청) — it can only be filed once. The review is reconstituted with different physician-reviewers than the original assessment to strengthen its independence, and submitting additional evidence documenting the disability's actual severity materially helps the outcome. If the objection is also denied, the applicant has another 90 days from that notice to escalate to an administrative appeal (행정심판, filed with the provincial Administrative Appeals Commission) or an administrative lawsuit (행정소송, filed with an administrative court) — the two channels most cases actually get resolved through, based on the reported rulings below. A one-page objection form is not enough on its own; it needs to be filed together with concrete supporting evidence capable of actually reversing the "not qualified" finding, and a well-documented objection also strengthens a later appeal if the objection itself is denied.
Three outcomes from this space are worth knowing before assuming a denial is final. In a Suwon District Court ruling, an applicant scored an IQ of 60 on testing but was found "not qualifying" by the local government based on the National Pension Service's review, which leaned on indirect materials — a school-life record and a "borderline" secondary assessment — rather than the applicant's own treating psychiatrist's direct diagnosis. The court overturned the denial, holding that the pension service's consulting physicians evaluated only indirect records without ever examining the applicant directly, while the treating physician who had actually observed and tested the applicant found an IQ of 70 or below. A companion Incheon District Court ruling reached the same result on similar facts, both reinforcing that a directly-treating physician's clinical opinion outweighs a paper-only consulting review.
In a Gyeonggi Administrative Appeals Commission case (2023경기행심1029), an applicant denied intellectual-disability registration despite IQ scores of 77 (2016), 66 (2017), and 61 (2022) won on appeal — the commission noted the applicant's unusually high processing-speed score paired with low verbal-comprehension and perceptual-reasoning scores didn't fit the typical pattern used to discount low IQ results, and that uneven school grades alone don't prove the absence of intellectual disability. The denial was reversed to a "severe" disability classification. But a similar-looking case (2023경기행심886) went the other way: an applicant with a post-accident IQ of 68 was denied because their pre-accident IQ had been 92, they'd passed some subjects and even a driving-test and a computer certification after the accident — the commission held the cognitive decline, while real, didn't reach the disability threshold, and the objection was dismissed. The dividing line in these paired cases is evidentiary depth — a single IQ number rarely wins or loses a case on its own; what moves the outcome is whether the file also documents functional impact in daily life, consistent testing trends, and, where relevant, a medical opinion tying the decline to a specific documented cause.
Registration unlocks more than a card — it opens income-support and cost-offset programs. As of January 2025, the 장애인연금 (disability pension) for severely-disabled adults aged 18+ pays up to ₩432,510/month (a basic payment of ₩342,510 plus a supplemental payment of ₩30,000–90,000 depending on income tier), adjusted annually for inflation and available to applicants under an income/asset threshold (₩1.38M/month for a single-person household in 2025). Adults with a non-severe disability receive a separate disability allowance of ₩60,000/month, and disabled children under 18 receive up to ₩220,000/month. Registration also connects to a broader welfare structure this office routinely helps clients navigate alongside the registration itself — medical and rehabilitation support, education and childcare accommodations, employment and business-loan programs, utility discounts, tax benefits, and community rehabilitation-facility services.
Disability Classification & Registration Guidance
Get in touch about thisThe six grades were consolidated into two bands: "severe" disability (roughly the old Grades 1–3) and "not severe" disability (roughly the old Grades 4–6). Every disability type's classification table is now written in terms of these two bands rather than a specific number. Benefit eligibility — including the disability pension amount — is generally tied to which band you fall into, so the underlying medical severity still matters as much as it did before 2019, just expressed differently.
Generally, foreign-produced medical records aren't accepted for the disability-severity assessment. The exception is when the disability is unmistakably permanent and self-evident — limb amputation, certain deformity-type disabilities, spinal fusion, congenital cerebral palsy, eye enucleation, an organ transplant, or an irreversible ostomy. In those cases, a notarized Korean translation of the original surgical or treatment record can be submitted instead of a domestic treatment history, though the reviewing agency may still request supplementary documents.
You have 90 days from the notice date to file a one-time objection (이의신청), which is reviewed by a different set of physician-reviewers than the original assessment. If that's also denied, you have another 90 days from that second notice to escalate to an administrative appeal with the provincial Administrative Appeals Commission or an administrative lawsuit in administrative court. Missing either 90-day window generally closes that avenue, so timing the filing is as important as the substance of the evidence.
Reported court rulings say yes, when the pension service's consulting physicians only reviewed indirect materials — like a school-life record — without ever examining the applicant directly, while the applicant's treating physician had actually observed and tested them. Two separate district courts overturned "does not qualify" decisions on exactly this reasoning. That doesn't guarantee every case wins, but it's a strong argument to raise in an objection or appeal when the denial rests mainly on a paper review.
Pancreatic disability (췌장장애) became the 16th recognized type effective July 1, 2026, covering severe, treatment-resistant endocrine dysfunction of the pancreas. It requires 6+ months of active multi-dose insulin therapy or insulin-pump use with no improvement, confirmed by two C-peptide test results at least 3 months apart. It doesn't retroactively change any existing registration under a different type — it's a new filing option for applicants whose condition fits this specific criteria who weren't previously eligible under any other category.
For severely-disabled adults 18+, the disability pension currently pays up to ₩432,510/month, combining a basic payment adjusted for inflation with an income-tiered supplemental payment; a separate disability allowance and a disability-child allowance apply to non-severe adults and to children under 18. Registration also opens access to medical and rehabilitation support, education and childcare accommodations, employment programs, utility discounts, tax benefits, and community rehabilitation-facility services — most of which require the disability card as a prerequisite to even apply.
