01 / Occupational profile
Your HM occupational profile
Patient handling and lifting
Common occupational factor
Repetitive lifting, transferring, and positioning of patients, and litter-bearing under field conditions for FMF corpsmen, are recognized occupational stressors on the spine and shoulders.
FMF combat load and deployment exposure
Location-dependent
FMF corpsmen assigned to Marine infantry, artillery, or reconnaissance units carry a load and face combat-contact and blast risk comparable to the unit they are embedded with, though this varies by assignment and era.
Traumatic and operational stress exposure
Assignment-dependent
Corpsmen who treated combat casualties, including mass-casualty events, or who lost patients under their care, carry a distinct trauma-exposure profile beyond direct combat contact.
Infectious and bloodborne-pathogen exposure
Common occupational factor
Clinical duties in sick bay or the field regularly involve exposure to bodily fluids, sharps, and infectious materials, including needlestick incidents.
Shipboard shift work and sleep disruption
Common occupational factor
Rotating watch schedules aboard ship, particularly for sick-bay and IDC assignments, disrupt normal circadian rhythm over sustained sea-duty periods.
02 / Your service
What did you actually do?
Your MOS is the starting point. Your actual assignment, era, equipment, location, and duties determine which parts of the occupational history are relevant. Use the Evidence Builder below to select your actual duties and see records that may corroborate them.
Hospital corpsmen provide first-line and follow-on medical care across the full range of Navy and Marine Corps operations. FMF-assigned corpsmen deploy embedded in Marine infantry, artillery, and reconnaissance units, carrying medical gear in addition to personal combat equipment, treating combat casualties under fire, and sharing the same field-living, blast, and combat-stress exposures as the Marines in their unit. Shipboard and shore-based corpsmen work in sick bay or clinical settings, performing patient assessment, wound care, immunizations, and emergency response, often on rotating watch schedules that disrupt sleep, and with routine exposure to bodily fluids and sharps. Independent Duty Corpsmen serve without a physician aboard smaller vessels or in isolated units, carrying expanded clinical responsibility.
Duty content differs sharply by assignment. A Fleet Marine Force (FMF) corpsman attached to a Marine infantry battalion carries a load and combat-exposure profile close to the infantrymen alongside whom they serve, while a corpsman assigned to a hospital ship or a shore medical treatment facility has a very different physical and psychological exposure history.
Duties that may vary by assignment
- FMF assignment: carrying a medical aid bag and personal combat load on foot movements with an infantry, artillery, or reconnaissance unit
- Treating combat casualties under fire, including hemorrhage control, airway management, and medical evacuation coordination
- Shipboard or shore sick-bay duty: patient intake, wound care, immunizations, and emergency response
- Repetitive patient lifting, transferring, and positioning, including litter-bearing in field and shipboard settings
- Rotating watch schedules and shift work disrupting normal sleep patterns, particularly aboard ship
- Routine exposure to bodily fluids, needlesticks, and infectious materials during clinical care

Building your occupational history
Records matter because they can connect a job title to an individual's actual work and circumstances.
Patient handling and lifting
Records that may corroborate it
- · Navy service record page entries and evaluations describing sick-bay or field medical duty
- · Sick call and physical therapy entries for back or shoulder complaints
- · LIMDU or equivalent light-duty documentation
Limit: That the rating commonly involves patient handling does not establish that a specific joint was injured in service; a current diagnosis and nexus are still required.
FMF combat load and deployment exposure
Records that may corroborate it
- · Orders documenting FMF assignment and the specific Marine unit served with
- · Combat Action Ribbon, Fleet Marine Force Warfare insignia qualification, or award citations
- · Post-Deployment Health Assessment / Reassessment (DD 2796/2900) entries
Limit: FMF assignment alone does not establish a specific event occurred; documentation of the deployment and unit history supports, but does not substitute for, evidence of the claimed incident.
Traumatic and operational stress exposure
Records that may corroborate it
- · VA Form 21-0781 stressor statement describing specific casualty-care events
- · Unit after-action reports and command chronologies
- · Behavioral-health treatment entries during or after service
Limit: A described stressor is one element of a PTSD claim. A diagnosis meeting DSM-5 criteria and a link to the stressor under 38 CFR § 3.304(f) are also required.
Infectious and bloodborne-pathogen exposure
Records that may corroborate it
- · Occupational exposure or needlestick incident reports in the health record
- · Immunization and post-exposure prophylaxis records
- · Navy service record page entries documenting clinical assignment
Limit: General exposure risk typical of the rating does not establish a current infectious disease diagnosis without documented incident and clinical follow-up.
Shipboard shift work and sleep disruption
Records that may corroborate it
- · Sea-service history and ship assignment records
- · Watch bill or rotation schedules where retained
- · Sick call entries for sleep-related complaints during or after sea duty
Limit: Sea-duty shift work typical of the rating does not by itself establish a current sleep disorder without a current diagnosis and supporting evidence.
04 / Evidence standard
What your MOS can — and cannot — establish
May help document
Work performed, circumstances of service, consistency of an alleged exposure, and the nature or duration of duties where supported by individual records.
Does not automatically establish
A diagnosis, medical causation, severity, percentage, presumption, or entitlement to service connection.
05 / Medical evidence
Conditions that may be relevant to the occupational history
This is not a list of conditions to claim. A veteran's actual diagnosis and individual service record determine relevance; occupational evidence is not medical causation.
Mental health +
PTSD, depressive, and anxiety disorders
Why the occupation may matter: Direct exposure to combat casualties, patient loss, or personal combat contact during FMF deployment is a documented stressor category for this rating.
Records and clinical evidence: A DSM-5 diagnosis, a described and where possible corroborated stressor, and treatment records showing occupational and social impairment.
Occupational history alone does not establish this diagnosis or its medical relationship to service.
Lumbar spine +
Lumbar strain and degenerative disc disease
Why the occupation may matter: Repetitive patient lifting and, for FMF corpsmen, litter-bearing under load place cumulative stress on the lumbar spine.
Records and clinical evidence: Current imaging, in-service documentation of clinical or field duty, and an opinion addressing cumulative loading.
Occupational history alone does not establish this diagnosis or its medical relationship to service.
Shoulder +
Rotator cuff pathology and shoulder strain
Why the occupation may matter: Repeated patient transfers and positioning load the shoulders over a career.
Records and clinical evidence: Current imaging or exam findings and a nexus opinion addressing repetitive patient-handling demands.
Occupational history alone does not establish this diagnosis or its medical relationship to service.
Neurologic / TBI +
TBI residuals and headaches
Why the occupation may matter: FMF corpsmen embedded with infantry, artillery, or reconnaissance units share the blast-exposure risk of the unit they serve with.
Records and clinical evidence: Documentation of the event through unit records, reported symptoms, and current neurological findings under the DC 8045 facets.
Occupational history alone does not establish this diagnosis or its medical relationship to service.
Sleep +
Insomnia and other sleep disorders
Why the occupation may matter: Rotating watch schedules and combat-related hypervigilance can disrupt sleep during and after service.
Records and clinical evidence: Current sleep-study or clinical diagnosis, documentation of watch rotation or deployment history, and a nexus opinion.
Occupational history alone does not establish this diagnosis or its medical relationship to service.
Hearing +
Tinnitus and hearing loss
Why the occupation may matter: FMF corpsmen exposed to the same weapons and combat noise as their embedded unit face comparable hazardous-noise risk.
Records and clinical evidence: Audiometry or a tinnitus report, unit assignment documentation, and a nexus opinion.
Occupational history alone does not establish this diagnosis or its medical relationship to service.
Infectious / other +
Residuals of documented occupational exposure incidents
Why the occupation may matter: Needlestick or bodily-fluid exposure incidents documented in the health record can support a claim for related residual conditions.
Records and clinical evidence: The incident report, post-exposure treatment records, and current clinical findings tied to the documented event.
Occupational history alone does not establish this diagnosis or its medical relationship to service.
06 / Exposure record
ILER and toxic exposure
For applicable exposure-related claims, VA may review the Individual Longitudinal Exposure Record (ILER) and a toxic exposure risk activity (TERA) memorandum along with deployment and occupational records. An ILER entry does not automatically establish exposure or service connection.
07 / After a decision
Why a HM claim may still be denied
An exposure finding is not the same as a grant. These are examples from the researched guide, not predictions about a particular case.
VA may accept
A duty or event consistent with the service record
But may deny
A diagnosis, medical relationship, or rating element
Record to examine
Decision findings, service and private treatment records, examination rationale, and medical opinions.
FMF stressor described generally without corroborating unit records
A PTSD claim describing casualty care in general terms, without dates, unit, or a documented incident, is harder for VA to corroborate. Unit orders, deployment dates, and after-action reports strengthen the stressor statement.
Back or shoulder claim denied for lack of in-service documentation
Corpsmen, like other medical personnel, sometimes continued working through pain without a service treatment record entry describing it. Lay evidence and evaluation narratives describing patient-handling duty help fill that gap.
Sleep disorder attributed to lifestyle rather than shipboard duty
An examiner may attribute insomnia to non-service factors if the sea-service history and watch-rotation documentation are not part of the record.
Hearing claim denied absent hearing-conservation enrollment
Corpsmen not formally enrolled in a hearing-conservation program, particularly shore or shipboard assignments, may need unit assignment records to establish comparable noise exposure to their embedded unit.
Rating understates severity from a single exam snapshot
A grant may still understate severity when the exam does not account for flare-ups or repetitive-use loss under 38 CFR §§ 4.40, 4.45 and Correia v. McDonald.
Oakridge Claims / Appeals Focused
Already have a VA decision?
The important question is what VA accepted, what it rejected, and why. A decision review considers the decision, examinations, and the complete record — including private and VA records that may need development. Oakridge is appeals-focused — core work is post-decision, but initial and new claims are accepted on a case-by-case basis (no fee for pre-decision work).
Fees for eligible post-decision representation are governed by a written agreement. See fee details. No outcome is guaranteed.
HM questions
Does serving as a corpsman automatically qualify me for PTSD benefits?
No. HM service, particularly FMF assignment, supports that combat-casualty and traumatic exposure was more likely, but a PTSD claim still requires a DSM-5 diagnosis, a described stressor, and a link between them under 38 CFR § 3.304(f).
I was an FMF corpsman — does that prove I was exposed to the same things as the Marines I served with?
It supports it strongly, since FMF corpsmen deploy embedded with the unit. Documenting your specific unit, orders, and deployment dates helps tie your exposure to that unit's combat history.
Can shipboard duty support a hearing-loss claim?
It can, depending on your specific work environment (engineering spaces, flight deck, weapons stations). Sick-bay-only duty typically carries lower baseline noise exposure than these spaces, so documenting where you actually worked matters.
I had a needlestick incident in service — is that automatically compensable?
No. The incident report and post-exposure treatment establish the event. A current diagnosis of a residual condition tied to that specific exposure is still required for service connection.
Does my HM rating prove I have a bad back?
No. It documents duties involving patient handling and lifting consistent with back strain, but a current diagnosis and a nexus opinion connecting it to service are still needed.
Can Reserve or IDC service support a claim?
It can. Independent Duty Corpsmen and Reservists have the same underlying claim elements; duty status (active duty, active duty for training, inactive duty for training) affects which injuries are covered.
What records best show what I did as a corpsman?
Navy service record page entries and evaluations describing your specific assignment, sea-service history and ship assignment records, FMF orders and Warfare insignia qualification if applicable, and any occupational exposure incident reports.
