Gulf War Syndrome (GWS), now formally recognized as Medically Unexplained Chronic Multisymptom Illness (MUCMI), describes a collection of chronic, debilitating symptoms experienced by veterans who served in the Gulf War and surrounding regions. While MUCMI is the accepted term, many veterans and resources still refer to these conditions as Gulf War Syndrome, Gulf War Illness, or Chronic Multisymptom Illness (CMI).
This guide provides a comprehensive overview of Gulf War Syndrome symptoms, presumptive conditions, VA disability ratings, and step-by-step instructions on how to file a claim.
What Is Gulf War Syndrome (MUCMI)?
Gulf War Syndrome refers to an umbrella of chronic and unexplained symptoms commonly reported by veterans who served in the Southwest Asia Theater of Operations or Afghanistan. These symptoms often include fatigue, headaches, joint pain, memory issues, and gastrointestinal disorders.
The VA evaluates Gulf War Syndrome (MUCMI) symptoms individually, assigning separate ratings to each condition. However, overlapping symptoms are not rated twice due to the Pyramiding Rule, which prevents duplicate ratings for the same impairment.
How the VA Rates Gulf War Syndrome (MUCMI)
The VA assigns ratings to conditions associated with MUCMI, such as chronic fatigue syndrome, fibromyalgia, and functional gastrointestinal disorders, based on their severity and impact on daily life. Each condition is rated separately unless symptoms overlap, in which case a single rating applies.
Below are common MUCMI-related conditions and their assigned ratings.
Chronic Fatigue Syndrome (CFS)
Chronic Fatigue Syndrome (38 C.F.R. § 4.88a, Diagnostic Code 6354) is rated based on its severity and how it limits your daily activities:
- 100%: Nearly constant and so severe as to restrict routine activities almost completely, making work and self-care exceptionally difficult.
- 60%: Nearly constant and restricts routine daily activities to less than 50% of pre-illness levels, or episodes of incapacitation lasting at least six weeks per year.
- 40%: Nearly constant and restricts routine daily activities to 50-75% of pre-illness levels, or episodes of incapacitation lasting four to six weeks per year.
- 20%: Symptoms are present but restrict routine daily activities by less than 25% of pre-illness levels, or episodes of incapacitation lasting two to four weeks per year.
- 10%: Symptoms wax and wane, causing incapacitation for at least one but less than two weeks annually, or are controllable by medication.

Fibromyalgia
Fibromyalgia (38 C.F.R. § 4.71a, Diagnostic Code 5025) is rated based on the presence of widespread musculoskeletal pain and associated symptoms such as fatigue, sleep disturbances, and headaches:
- 40%: Constant or nearly constant symptoms that are refractory to therapy.
- 20%: Episodic symptoms occurring more than one-third of the time, often triggered by stress or overexertion.
- 10%: Symptoms require continuous medication for control.

Irritable Bowel Syndrome (IBS)
IBS (38 C.F.R. § 4.114, Diagnostic Code 7319) ratings depend on the frequency and severity of symptoms:
- 30%: Abdominal pain related to defecation at least one day per week in the past three months, with two or more of the following: changes in stool frequency or form, urgency, mucorrhea, bloating, or subjective distension.
- 20%: Abdominal pain for at least three days per month, with two or more of the symptoms above.
- 10%: Abdominal pain at least once in the past three months, with two or more of the symptoms above.

Additional MUCMI-Related Conditions and Their Ratings
The following conditions may also fall under the category of MUCMI. Each has unique diagnostic codes and ratings based on severity:
- Headaches (Migraines): Rated 0-50%, depending on frequency and level of incapacitation.
- Sleep Disturbances (Insomnia): If related to mental health, rate under Mental Health Disorders.
- Neurological and Psychological Symptoms: Rated as appropriate under Mental Disorders.
- Skin Conditions (Dermatitis): Rated 0-60% depending on the percentage of body affected.
- Respiratory Conditions: Rate under the applicable respiratory condition codes, such as obstructive sleep apnea.
- Menstrual Disorders: Rated under the appropriate gynecological codes based on symptoms and severity.
- Cardiovascular Signs or Symptoms: Rate under the appropriate cardiovascular codes based on diagnostic findings.
Can You Get 100% VA Disability for Gulf War Syndrome?
Yes, veterans with severe symptoms affecting multiple body systems may qualify for a 100% VA disability rating. This rating often combines individual symptoms evaluated under MUCMI to reflect their collective impact.
Presumptive Conditions for Gulf War Veterans
The VA presumes that certain chronic illnesses are service-connected if they meet specific criteria. These conditions include:
Medically Unexplained Chronic Multisymptom Illnesses (MUCMIs)
- Chronic Fatigue Syndrome (CFS): Severe, unexplained fatigue.
- Fibromyalgia: Widespread muscle pain and stiffness.
- Functional Gastrointestinal Disorders: Includes IBS and functional dyspepsia.
Undiagnosed Illnesses
Must persist for six months or more. Symptoms may include, but are not limited to:
- Chronic fatigue
- Joint and muscle pain
- Headaches
- Memory and cognitive issues
- Respiratory problems
- Skin conditions
Infectious Diseases
Gulf War veterans may also qualify for presumptive service connection for diseases such as:
- Brucellosis
- Coxiella burnetii (Q fever)

- Afghanistan (after September 19, 2001)
Service in operations like Desert Storm, Desert Shield, Operation New Dawn, and Operation Iraqi Freedom also qualifies under the Gulf War presumption.
Gulf War Environmental Exposures
Veterans serving in the Gulf War often encountered harmful environmental hazards that may have contributed to their symptoms, including:
- Burn Pit Toxins: Exposure to smoke and chemicals from burning waste.
- Oil Well Fires: Inhalation of soot and toxic chemicals from over 750 burning wells.
- Nerve Gas Antidotes: Use of pyridostigmine bromide pills.
- Pesticides and Insecticides: Widespread use of chemical repellents.
- Fine Sand Particles: Inhalation of desert sand and particulate matter.
How to File a VA Claim for MUCMI
Steps to File a Claim
- Gather Evidence: Obtain medical records, VA health exam results, and personal statements documenting symptoms lasting six months or more.
- File VA Form 21-526EZ: Submit your claim online, by mail, or through a VA-accredited representative.
- Complete a C&P Exam: Clearly describe how your symptoms affect daily activities, work, and quality of life.
- Include Lay Evidence: Statements from family, caregivers, or coworkers can help demonstrate how your symptoms impact your life.
Why Are Gulf War Syndrome Claims Denied?
According to the Government Accountability Office (GAO), VA denies over 80% of Gulf War-related claims, citing difficulties in evaluating medically unexplained symptoms. Veterans often face longer wait times and require additional evidence to support their claims.
