SSR 12-2p in 2026: How SSA Evaluates Fibromyalgia, the 1990 vs 2010 ACR Criteria, and the Longitudinal Evidence That Wins These Claims

Published May 31, 2026 by Anthony Albert, Benefits Research Director at Disability Exchange. Reading time: 15 minutes.

Fibromyalgia is one of the hardest impairments to win at SSA. The pain is real. The fatigue is real. The brain fog is real. But almost none of it shows up on an X-ray or in a blood test. For years, disability examiners denied fibromyalgia claims by default because the impairment didn't fit the agency's usual playbook of objective findings. In 2012, SSA finally published Social Security Ruling 12-2p, the first and still only ruling that tells adjudicators how to handle fibromyalgia. It's the rule book your case rises or falls on.

The ruling did two things. It told adjudicators that fibromyalgia can be a medically determinable impairment when a licensed physician diagnoses it under either the 1990 American College of Rheumatology criteria or the 2010 ACR Preliminary Criteria. And it told them that because fibromyalgia symptoms wax and wane, they have to look at a longitudinal record, not a single visit, before deciding whether the impairment is severe and lasting. That second piece is where most claims get won or lost in 2026.

The Statutory and Regulatory Setup

Fibromyalgia isn't in the Listing of Impairments. There's no listing 14.07 or 1.20 you can meet to get a step-three approval. That means every fibromyalgia case has to be decided at step four or step five of the sequential evaluation, on residual functional capacity. SSR 12-2p doesn't change that. What it does is tell adjudicators how to decide whether fibromyalgia counts as a medically determinable impairment in the first place, what evidence is relevant, and how to weigh longitudinal records.

The implementing guidance for adjudicators is in POMS DI 24515.076, which tracks the ruling almost word for word and adds workflow guidance for disability determination services. The ruling itself is published at SSR 12-2p on the SSA rulings website.

The five-step evaluation still applies. The SSR 12-2p change is mostly at step two (severe impairment) and step four (RFC). At step two, an adjudicator can't reject fibromyalgia as not severe just because labs and imaging are normal. At step four, the RFC has to account for pain, fatigue, and cognitive limits that come with the impairment, not just for what's visible on testing.

What SSR 12-2p Requires for a Medically Determinable Impairment

The threshold question is whether fibromyalgia counts as a medically determinable impairment (MDI) under 20 CFR 404.1521. If it doesn't, the claim ends at step two and no RFC analysis happens. SSR 12-2p says fibromyalgia is an MDI when three conditions are met:

1. A licensed physician (MD or DO) diagnoses fibromyalgia
2. The diagnosis is supported by either the 1990 ACR criteria or the 2010 ACR Preliminary Criteria
3. The diagnosis isn't inconsistent with other evidence in the record

The licensed-physician requirement matters. A nurse practitioner's chart note saying "patient reports fibromyalgia" doesn't satisfy SSR 12-2p. Neither does a chiropractor's letter. The diagnosis has to come from an MD or DO who has examined the patient, ruled out other conditions, and recorded the findings.

The 1990 ACR Criteria

The original ACR criteria, published in 1990, require two findings to be present at the same time:

1. A history of widespread pain in all four quadrants of the body (right side, left side, above the waist, below the waist) plus the axial skeleton (cervical spine, anterior chest, thoracic spine, or low back), lasting at least three months.
2. At least 11 of 18 tender points on physical examination, tested with approximately nine pounds of digital pressure, located bilaterally at:
   • Occiput (suboccipital muscle insertions)
   • Low cervical (anterior aspects of C5 to C7)
   • Trapezius (midpoint of upper border)
   • Supraspinatus (above scapular spine near medial border)
   • Second rib (just lateral to second costochondral junction)
   • Lateral epicondyle (2 cm distal to epicondyle)
   • Gluteal (upper outer quadrant of buttocks)
   • Greater trochanter (posterior to trochanteric prominence)
   • Knee (medial fat pad proximal to joint line)

The 1990 criteria also require that other disorders that could explain the symptoms are excluded. In practice, that means the physician has ordered or reviewed labs to rule out rheumatoid arthritis (RF, anti-CCP), lupus (ANA), polymyalgia rheumatica (ESR, CRP in someone over 50), inflammatory arthritis (ESR, CRP, joint imaging), thyroid disease (TSH), and other conditions whose pain and fatigue could mimic fibromyalgia.

The 2010 ACR Preliminary Criteria

The 2010 ACR criteria don't require tender point counts. They use a symptom-based approach with two scored scales:

Widespread Pain Index (WPI). Count the number of body areas (out of 19) where the patient has had pain over the last week. Areas include shoulder girdle (left, right), upper arm (left, right), lower arm (left, right), hip/buttock (left, right), upper leg (left, right), lower leg (left, right), jaw (left, right), chest, abdomen, upper back, lower back, neck.

Symptom Severity (SS) scale. Three core symptoms scored 0 to 3 each (fatigue, waking unrefreshed, cognitive symptoms) plus a 0 to 3 count of additional somatic symptoms (muscle pain, IBS, fatigue/tiredness, thinking or remembering problems, muscle weakness, headache, abdominal pain or cramps, numbness or tingling, dizziness, insomnia, depression, constipation, upper abdominal pain, nausea, nervousness, chest pain, blurred vision, fever, diarrhea, dry mouth, itching, wheezing, Raynaud, hives, tinnitus, vomiting, heartburn, oral ulcers, loss of taste, change in taste, seizures, dry eyes, shortness of breath, loss of appetite, rash, sun sensitivity, hearing difficulties, easy bruising, hair loss, frequent urination, painful urination, bladder spasms). Max SS score is 12.

The 2010 criteria are satisfied if either:

• WPI of 7 or higher AND SS score of 5 or higher
• WPI of 3 to 6 AND SS score of 9 or higher

Plus the symptoms have been present at a similar level for at least three months, and other disorders that could explain the symptoms have been ruled out.

SSR 12-2p accepts both criteria sets. Most practicing rheumatologists in 2026 use the 2010 criteria because tender point exams have largely been retired in clinical practice, but the 1990 criteria are still recognized for older records and for SSA evidentiary purposes.

The Longitudinal Record Requirement

This is the part of SSR 12-2p that decides most claims. The ruling tells adjudicators that fibromyalgia symptoms wax and wane, so a one-time exam isn't enough to evaluate the impairment. They need a longitudinal record that shows the impairment over time.

Practically, that means 12 months or more of treating records that include:

• Visit notes showing symptoms over time, not just at one point
• Multiple treatment attempts (medications, physical therapy, lifestyle changes)
• Response to treatment (or lack of response)
• Functional limits documented at each visit (sleep, fatigue, cognitive function, pain location, pain intensity)
• Any specialist referrals or co-occurring impairment workups

A six-month gap in treatment can be used by an adjudicator to argue the impairment isn't severe enough to need continuous medical care. Patients with insurance gaps, transportation problems, or limited rheumatology access in their area should document the reason for gaps in writing through the rep brief or through statements to the ALJ. This is consistent with SSR 18-3p on failure to follow prescribed treatment, which gives claimants the chance to explain treatment gaps for good cause reasons including financial hardship.

What the Treating Source Should Document

The strongest fibromyalgia claims have treating-source records that look like a deliberate evidentiary build-out, even if the doctor wasn't thinking about disability when writing them. Here's what an SSA-friendly fibromyalgia chart looks like:

Most treating physicians don't document functional limits at every visit. They document symptoms and treatment. That leaves a gap that the representative has to fill with a treating-source opinion at the time of the SSDI application, usually a Residual Functional Capacity questionnaire. The questionnaire asks for specific limits and the physician's clinical basis for each one.

How RFC Translates Fibromyalgia Into a Disability Finding

Once SSR 12-2p establishes fibromyalgia as an MDI, the claim moves through the five-step sequential. Step three rarely matters because fibromyalgia isn't a listed impairment. The case decides at step four (can you do past relevant work) or step five (can you do other work in the national economy).

The RFC for a typical fibromyalgia claimant who wins includes some or all of:

• Sit, stand, or walk no more than 4 to 6 hours total in an 8-hour day
• Lift no more than 10 to 20 pounds occasionally, less frequently
• Need for unscheduled breaks of 10 to 15 minutes every 1 to 2 hours
• Off-task more than 15 percent of the workday due to pain and fatigue
• Absent from work more than 2 days per month due to flares
• Limited ability to maintain attention and concentration on simple tasks for 2-hour blocks
• Limited fingering and handling on bad days

At an ALJ hearing, the vocational expert is asked about each of these limits. The two RFC limits that usually decide the case are the off-task percentage and the absence rate. A claimant who would be off-task more than 15 percent of the day, or absent more than 2 days per month, is generally considered unemployable in competitive work according to most vocational expert testimony. If the RFC includes those limits and they're supported by the medical record, the claim wins at step five.

The treating-source opinion under 20 CFR 404.1520c isn't entitled to controlling weight anymore (the old treating physician rule was replaced in 2017), but it remains highly relevant if it's supported by the longitudinal record and consistent with the rest of the evidence. A well-written RFC questionnaire from a treating rheumatologist is still the single most important piece of evidence in a fibromyalgia SSDI case.

Co-Occurring Impairments That Strengthen Fibromyalgia Claims

Most winning fibromyalgia claims aren't just fibromyalgia. They include at least one or two co-occurring impairments that add to the combined limits at step three and step four. Common pairings:

• Depression or anxiety disorder. The mental impairment is evaluated under the 12.04 or 12.06 listings, sometimes meeting or equaling. Even when not meeting a listing, the mental RFC limits (concentration, persistence, pace) combine with the fibromyalgia physical RFC.
• Chronic migraine or headache disorder. Adds documented absent-from-work days during migraine episodes. Often supported by neurology records and medication trials.
• Irritable bowel syndrome (IBS). Adds unscheduled bathroom break frequency to the RFC. SSR 12-2p specifically lists IBS as one of the symptoms relevant to the 2010 ACR criteria.
• Chronic fatigue syndrome (CFS/ME). Many patients meet criteria for both fibromyalgia and CFS. SSR 14-1p covers CFS evaluation and uses a similar longitudinal-record approach. The combined effect is often more disabling than either alone.
• Cervical or lumbar spine impairment. Adds objective imaging support to a case that's otherwise largely symptom-based. Evaluated under the revised listings 1.15 and 1.16.
• Sleep apnea. Adds documented fatigue, decreased cognitive function, and a polysomnography-based diagnosis. Pairs well with the "waking unrefreshed" element of the 2010 ACR criteria.

SSA evaluates the combined effect of all medically determinable impairments at every step of the sequential. A claimant whose fibromyalgia alone produces a marginal RFC may have a clearly disabling RFC when fibromyalgia, depression, and migraines are evaluated together. The representative's job at the hearing is to make sure the ALJ considers the combined effect, not just the most-documented impairment.

Worked Examples

Example 1: Carla, California, Rheumatologist-Diagnosed Fibromyalgia with Depression

Carla is 52, worked as a hospital admissions clerk for 18 years. She started having widespread pain at 47, was diagnosed with fibromyalgia by a rheumatologist at 48 under the 2010 ACR criteria (WPI 12, SS 9). She also has major depressive disorder with a current GAF of 50. Her rheumatologist sees her every 8 weeks, has tried duloxetine, milnacipran, pregabalin, and amitriptyline with partial response. Her psychiatrist has been treating the depression for three years.

The treating rheumatologist completed an RFC questionnaire noting sit/stand/walk limits, 20 percent off-task, 3 absences per month, and limited handling on bad days. The psychiatrist documented marked limits in concentration and moderate limits in adapting. Carla's claim was approved at the ALJ hearing on the combined RFC. The vocational expert testified that no jobs exist in the national economy for someone who is off-task 20 percent of the time and absent 3 days a month. See California disability data for more on ALJ approval rates.

Example 2: Tomas, Texas, Internist-Diagnosed Fibromyalgia Without Rheumatologist Access

Tomas is 45, worked construction for 22 years. He developed widespread pain and fatigue at 41, was diagnosed by his family medicine physician under the 2010 ACR criteria after a workup that ruled out RA, lupus, and thyroid disease. He doesn't have access to a rheumatologist in his rural area. His PCP documented the WPI and SS scores at each visit, ordered exclusion labs, and managed him on duloxetine and gabapentin.

The initial denial said "diagnosis not supported by acceptable medical source." On reconsideration, his representative submitted the PCP's complete chart with the WPI/SS documentation and a statement from the PCP explaining the diagnostic process. At the ALJ hearing, the judge accepted the PCP as an acceptable medical source (the family medicine physician is an MD, satisfying SSR 12-2p's licensed-physician requirement), and the RFC limited Tomas to less than sedentary work. Approved at hearing. See Texas SSDI data.

Example 3: Priya, Florida, Tender-Point Exam Under 1990 Criteria

Priya is 39, formerly a teacher. Her rheumatologist diagnosed her under the 1990 ACR criteria at 36, with 14 of 18 tender points on physical examination and widespread pain in all four quadrants for over six months. She has co-occurring IBS, migraines, and an anxiety disorder. She's been on multiple medications, in cognitive behavioral therapy for two years, and on a graded exercise program with limited improvement.

Her initial claim was approved on the medical record alone. The DDS examiner found her impairments severe at step two, found that her combined RFC (less than sedentary plus moderate concentration limits) precluded her past work as a teacher and any other work in the national economy. Approved at initial. See Florida disability statistics.

Example 4: Marcus, New York, Long Treatment Gap Argued as Severity

Marcus is 49, worked retail management. Diagnosed with fibromyalgia at 44 by a rheumatologist, then lost his health insurance at 45 after job loss and went 14 months without specialist care. He saw his PCP twice during that gap and was on samples and over-the-counter medications. After getting Marketplace coverage at 46, he resumed rheumatology care and was finally able to file SSDI at 47.

The initial denial cited the treatment gap as evidence the impairment wasn't severe. On appeal, his attorney pulled records from the PCP visits during the gap, submitted bank records showing the insurance loss timeline, and provided a representative brief arguing the gap was due to financial hardship under SSR 18-3p good cause analysis. The ALJ accepted the explanation, focused on the longitudinal record from before and after the gap, and approved the claim. See New York SSDI processing data.

State-by-State Patterns

• California Strong rheumatology access in urban areas. ALJ approval rates for fibromyalgia claims among the higher in the country at hearing level
• Texas Mixed rheumatology access; rural claimants often diagnosed by family medicine physicians. Initial approval rates lower than national average
• Florida Moderate rheumatology density. High volume of fibromyalgia claims; ALJ backlog varies significantly by region
• New York Strong specialist access. Hearing level approval rates higher when treating-source RFC opinions are well-documented
• Illinois Solid rheumatology coverage in Chicago metro; varies in downstate counties

Common Mistakes That Sink Fibromyalgia Claims

1. Insufficient longitudinal record. Fewer than 12 months of treating records, or large gaps without documented good-cause explanation, lets adjudicators argue the impairment isn't severe and lasting.
2. Diagnosis by a non-physician. Nurse practitioners and chiropractors can support the record but cannot anchor the diagnosis under SSR 12-2p. Without an MD or DO diagnosis, the claim can be denied at step two.
3. Missing exclusion workup. If labs don't rule out RA, lupus, thyroid disease, and other mimics, the adjudicator can say the diagnosis isn't reliable. Make sure CBC, ESR, CRP, TSH, ANA, RF, and anti-CCP are in the record.
4. Symptom-only chart notes without functional documentation. Visit notes that describe symptoms but never document how long the claimant can sit, stand, or work create an evidentiary gap that hurts at step four.
5. No treating-source RFC opinion. A treating physician who's willing to fill out an RFC questionnaire is the single most valuable evidence asset. Many claims fail because nobody asked the rheumatologist for a written opinion.
6. Inconsistent Function Reports. If the SSA-3373 says the claimant cooks daily but the medical record says they can't stand for more than 15 minutes, adjudicators use the inconsistency to discount credibility under SSR 16-3p.
7. Relying on the consultative exam. CE doctors see the claimant once. A bad CE day or a good CE day misrepresents the longitudinal picture. Patients should bring symptom diaries and treating physician contact info to the CE.
8. Skipping co-occurring impairments. A pure fibromyalgia claim is harder to win than a combined fibromyalgia plus depression plus migraines claim. Document everything.

What to Do Right Now

1. Confirm your fibromyalgia diagnosis is from a licensed physician (MD or DO). If not, ask your PCP or a rheumatologist to formally diagnose under SSR 12-2p criteria.
2. Pull at least 12 months of treating records. If there are gaps, document the reason in writing.
3. Make sure the exclusion labs are in the chart: CBC, ESR, CRP, TSH, ANA, RF, anti-CCP, basic metabolic panel.
4. Ask your treating rheumatologist or PCP to complete a Residual Functional Capacity questionnaire with specific sit, stand, walk, lift, off-task, and absence limits.
5. Document all co-occurring impairments: depression, anxiety, IBS, migraines, chronic fatigue, sleep apnea.
6. Keep a daily symptom diary for at least 30 days before applying. Include pain levels, fatigue, fibro fog episodes, sleep quality, and activity limits.
7. Get a Third-Party Function Report from a spouse, parent, or close friend who sees you on bad days.
8. If denied at initial, file the reconsideration within 60 days. Plan for the ALJ hearing as the level where the claim will likely be decided.
9. Retain a representative for the hearing level. Fibromyalgia hearings benefit from skilled cross of the vocational expert on off-task and absence limits.

Bottom Line

SSR 12-2p is the rule book for fibromyalgia SSDI claims. It tells adjudicators that fibromyalgia can be a medically determinable impairment when a licensed physician diagnoses it under the 1990 or 2010 ACR criteria with proper exclusion of other disorders. It tells them they need a longitudinal record because symptoms wax and wane. And it tells them to evaluate the impairment through the standard five-step sequential, with pain, fatigue, and cognitive limits accounted for in the RFC.

What it doesn't change is the basic difficulty of winning a fibromyalgia case at the initial level. Most fibromyalgia approvals happen at the ALJ hearing, where the claimant can testify, the vocational expert can be questioned on off-task and absence rates, and the combined effect of fibromyalgia plus depression or anxiety or migraines can be presented as a whole.

If you're filing now, the highest-impact things you can do are: get a clean MD-diagnosed record under the 2010 ACR criteria, build a continuous 12-month-plus treating history with documented exclusion labs, get a treating-source RFC opinion with specific function-by-function limits, and document every co-occurring impairment. Those four pieces are what move fibromyalgia claims from denials to approvals in 2026.
