Occupational health examinations and occupational-disease diagnosis in China

Start with symptoms and clinical urgency, not the administrative label

If a worker has acute breathing difficulty, altered consciousness, chemical burns, severe neurological symptoms, collapse, suspected poisoning or another urgent condition, use emergency medical services or the nearest appropriate facility. Tell clinicians the factual substance, process, duration, protective equipment and first aid if known, and bring the product label or safety data without delaying transport. Emergency clinicians diagnose and treat the immediate condition; they do not need a completed occupational-health examination, employer approval or work-injury recognition before providing necessary care.

Preserve ambulance, emergency, laboratory, imaging, consultation, admission and discharge records. Notify the employer and occupational-health contact after urgent needs are addressed and ask for preservation of the worksite, substance, ventilation, monitoring and coworker information. A clinical diagnosis such as dermatitis, hearing loss, asthma, poisoning or a lung abnormality can guide treatment, but it does not by itself establish a disease as a statutory occupational disease. Administrative follow-up should run alongside care, never replace it. Only qualified clinicians should interpret individual results or advise treatment and fitness for work.

Emergency care does not wait for an occupational-health examination, statutory diagnosis or work-injury recognition.

Separate the six records before choosing a provider

An ordinary health check evaluates general health. An occupational-health examination is targeted surveillance for a worker exposed to specified occupational hazards and is performed under filed scope before assignment, during employment or on departure. A suspected-occupational-disease notice records that further statutory evaluation may be necessary. An occupational-disease diagnosis certificate is issued through the specialised legal route. A diagnostic appraisal reviews a disputed diagnosis through the prescribed expert process. Work-injury recognition is the later social-insurance administrative decision.

Write the exact record needed at the top of the appointment request. If the employer says “go for a check,” ask whether it is a statutory occupational-health examination, which exposure and project it covers, whether it is before, during or after employment, and which filed institution will perform it. If a clinician says “possible occupational disease,” ask whether this is a clinical differential diagnosis, a suspected-disease report or a referral to a filed diagnosis institution. Mislabeling a routine visit as statutory diagnosis can create false expectations and lose time.

Understand the employer's prevention and occupational-health duties

The occupational-disease law places primary prevention duties on the employer. These include occupational-health management, hazard identification and declaration where required, workplace monitoring, engineering and personal protection, warning and training, emergency arrangements, and occupational-health surveillance for exposed workers. The employer must create and preserve individual occupational-health monitoring files containing occupational history, exposure history, examination results, diagnosis and treatment information and other prescribed material. A worker has rights to relevant occupational-health information and records under the governing process.

Ask for the employer's exact registered name, worksite, job titles and dates, processes, hazard names, monitoring results for the relevant posts and periods, protective-equipment issue and fit records, training, incident reports and the worker's occupational-health file. Do not ask a manager to invent historical exposure measurements when none exist. Preserve the refusal or explanation and identify alternative evidence such as purchase records, process descriptions, safety data sheets, coworker records, regulatory inspections or technical evaluations. Prevention compliance and an individual diagnosis are related but separate questions; a breach does not automatically prove a disease.

Use the correct before-assignment, during-employment and departure examination

For workers exposed to occupational hazards, the law requires occupational-health examinations at prescribed stages. A before-assignment examination helps identify whether the person can enter the relevant hazardous post and establishes a baseline. Periodic examinations during employment monitor effects of the relevant hazard. A departure examination records health status when leaving the exposed post. Special follow-up or emergency examinations can apply in specified circumstances. The employer bears the examination cost and should arrange the service; the worker should not be charged merely because the examination relates to employment.

Confirm that the examination request lists the actual hazard and project rather than a generic package. Bring prior occupational-health reports, identity information and occupational history requested by the institution. Ask when the written report will be issued, who receives the unit report and individual result, how privacy is protected, and what referral follows an abnormal or suspected finding. A departure examination should not be replaced casually with a standard recruitment physical. If employment is ending, request the examination and records promptly and preserve any refusal, but obtain qualified advice before drawing conclusions about termination rights.

Verify the provider's filed scope, exact category and project

Occupational-health examination institutions operate through a filing system and must have personnel, equipment, quality controls and a principal examiner suitable for their filed work. Provider scope matters. An institution may perform examinations for some hazard categories but not others, or operate multiple campuses with different capabilities. Check the current provincial or municipal health-authority directory for the legal institution name, address, filed categories and projects before a planned examination.

A hospital's reputation, basic-medical-insurance status or work-injury agreement status does not establish occupational-health examination scope. Similarly, an institution filed to examine workers is not necessarily filed to diagnose the suspected occupational disease. Ask the provider to confirm the exact service in writing and retain the appointment or commission form. If the worker has complex symptoms or needs treatment, ask whether a separate clinical department visit is needed; the occupational-health examination should not be treated as a substitute for medical care. Provider directories change, so verify close to the visit.

Read an examination report without turning it into a diagnosis

The institution should issue the prescribed examination report and individual result, explain relevant findings and handle records and privacy under the rules. Possible outputs can include no detected occupational contraindication, a condition requiring review, an occupational contraindication, another disease or abnormality, or suspicion of occupational disease. The exact terminology and follow-up depend on the hazard, standard and findings. Ask the examining institution to explain the administrative category and recommended next step in language the worker understands.

Do not translate “abnormal,” “contraindication” or “suspected” into a definitive occupational-disease diagnosis. Do not use a website or general practitioner to infer exposure causation from a single result. Preserve the complete report, raw test outputs where available, prior comparisons and referral. Ask whether the employer must remove the worker from a hazardous assignment, arrange review or refer for diagnosis, but leave individual fitness and treatment conclusions to the qualified institution and competent process. If a translation is needed, keep the Chinese original and avoid changing medical terminology.

Act on a suspected-occupational-disease finding

When an occupational-health examination institution discovers a suspected occupational disease, the rules require notification to the worker and employer and reporting to the relevant health authority. The employer must arrange diagnosis under the occupational-disease law. During diagnosis or medical observation for a suspected occupational disease, the employer may not terminate the labor contract on that ground, and the employer bears the related diagnosis and medical-observation costs. These protections do not mean the final diagnosis is predetermined.

Obtain the suspected-disease notice, referral, examination report and proof that the employer received it. Ask the employer in writing to identify the diagnosis institution, appointment, cost arrangement and contact person. If the employer does not act, contact a qualified diagnosis institution and the local health authority for the worker-access route rather than waiting indefinitely. Continue clinically necessary care separately. Record any proposed job transfer, leave classification or contract action and seek qualified advice if employment is threatened. This guide cannot determine whether a particular employment action is lawful.

Choose a qualified occupational-disease diagnosis institution

A worker may seek statutory occupational-disease diagnosis at a qualified institution located where the employer is situated, where the worker's household registration is located or where the worker habitually resides. Check the health-authority directory for the institution's filed diagnosis project and disease scope, not only its general name. Contact the institution before travelling to confirm intake, appointment, identity, translation, records, employer notification and whether another local institution is already handling the same diagnosis.

The current catalogue contains twelve broad classes and 135 diseases from 1 August 2025, but it is not a patient checklist. A lay diagnosis name may map to a statutory item only through the applicable diagnostic standard, and an included name still requires the necessary occupational and medical evidence. Ask the institution whether it handles the suspected disease and exposure, what complete materials start the formal period and how supplementation works. Do not shop among institutions for a preferred conclusion or file duplicate cases without disclosing the existing process.

Build the occupational history and exposure evidence file

Diagnosis considers the worker's occupational history, history of exposure to occupational-disease hazards, workplace hazard factors, monitoring and evaluation information, clinical presentation and auxiliary examination results. Build a chronological table covering every relevant employer, site, job, process, task, substance or physical factor, dates, hours or frequency, controls, protective equipment, incidents, coworker exposures and occupational-health examinations. Separate facts remembered by the worker from employer records and technical measurements.

Collect labor contracts, work permits, payroll, job descriptions, assignment and shift records, training, safety data sheets, labels, purchase or inventory records, workplace monitoring reports, technical evaluations, regulatory inspection documents, occupational-health files and complete clinical records. Preserve originals and describe gaps honestly. Do not estimate a concentration as if measured, copy another worker's dose or alter a job title to fit the catalogue. The diagnosis institution weighs evidence under the statutory standard; the website cannot decide whether exposure was sufficient or caused the condition.

Handle employer noncooperation and factual disputes lawfully

The employer must provide occupational history, exposure history, workplace hazard monitoring and other diagnosis information within the prescribed process. If it refuses or the worker disputes the information, the diagnosis institution can use other evidence and request investigation by the local health authority. The health authority may organise investigation or make a determination on workplace hazard factors under the governing procedure. Employer noncooperation therefore should be documented and escalated, not answered by creating substitute measurements.

Disputes over the existence of a labor relationship, job, post, work time or exposure history can require labor dispute arbitration. The diagnostic process can depend on that competent conclusion, which may affect timing. Ask the diagnosis institution for a written list of disputed facts, missing materials and any suspended period. Submit available payroll, direction, access, witness and permit evidence to the correct dispute route. Keep diagnosis, labor arbitration, health-authority investigation and work-injury recognition case numbers separate. Seek legal assistance early when an employer has closed, changed name, moved or denies the relationship.

Track the diagnosis certificate and the appraisal route

Under the diagnosis measures, the institution organises diagnosis after accepting the case and receiving complete materials. It ordinarily issues the occupational-disease diagnosis certificate within thirty days after the materials are complete. The period is linked to completeness and can be affected by investigation, factual disputes or necessary procedures. Ask for the acceptance status, complete-material date, supplementation notice and service method. A counter intake or medical appointment is not necessarily the date on which the thirty-day period begins.

Read the certificate for identity, employer, diagnosis, disease, exposure and date. If a party disputes the diagnosis, the occupational-disease law and measures provide an appraisal route through the designated local health authority and then, where permitted, a further provincial-level appraisal. Preserve the service date because filing periods apply. An appraisal is not a second routine clinic opinion, and a private specialist letter does not replace it. Obtain the current local form, authority, deadline and materials, and use qualified advice for a contested case.

Move from statutory diagnosis to recognition and benefits

A compliant occupational-disease diagnosis or appraisal certificate supplies the statutory medical evidence for the separate work-injury recognition application. The employer ordinarily should file recognition within thirty days after diagnosis or appraisal; if it does not, the worker, close relative or trade union ordinarily may file within one year. Preserve both dates and obtain the recognition receipt. The social-insurance authority does not reinvestigate the medical diagnosis itself as if it were a diagnosis institution, but it still handles jurisdiction, employment, documents and recognition under its legal role.

After recognition, treatment may move into the work-injury medical route, and labor-capacity assessment can follow when the condition is appropriately stable and affects work ability. Benefit responsibility can depend on insurance, employer history and employment changes. Diagnosis costs and appraisal costs are borne by the employer under the occupational-disease law. A diagnosis does not calculate disability or all compensation automatically. Ask each institution for its own next transaction and receipt rather than assuming a one-stop page means one combined approval.

Protect rights across former employers, job changes and missing insurance

Occupational disease can emerge after a worker leaves an exposed post or changes employers. Preserve the occupational-health file and departure examination before leaving. The law provides that a change of employer does not erase occupational-disease treatment rights already enjoyed, and the original employer's division, merger, dissolution or bankruptcy has statutory responsibility rules. When the current and former employers are disputed, build a timeline of exposure, legal-entity changes and insurance participation and obtain specialised advice on the responsible party.

If an employer required to insure the worker did not participate, that omission does not turn a confirmed occupational disease into an ordinary personal illness. The employer can remain responsible for statutory medical and living security and work-injury benefit items under the governing laws. Still complete diagnosis and recognition where required and obtain written agency directions. For a worker who has left China, ask the diagnosis and recognition authorities about physical attendance, records, representation, service and benefit qualification. Do not assume an overseas address cancels rights or that remote processing is always available.

Keep the five administrative states separate

Emergency care and 120 ambulance transport; an accident report; work-injury insurance participation; work-injury recognition; medical treatment or rehabilitation; labor-capacity assessment; benefit and responsible-payer calculation; and employment evidence are separate records and workflow layers. A workplace event can create several of them without completing the work-injury route. An internal accident notification tells the employer what happened. A production-safety report, when legally required, alerts the safety authority and supports rescue and investigation. A hospital record documents presentation, findings and treatment. A work-injury recognition decision determines the administrative character of the accident or statutory occupational disease. A labor-capacity assessment later grades work-function or self-care impairment after recognition and appropriate medical stability. None of these records is a substitute for the others, and the order can matter.

Create a status table with one row for emergency care, employer notice, safety reporting if applicable, recognition application, recognition decision, rehabilitation confirmation, labor-capacity assessment and benefit payment. For each row record the responsible party, authority, submission date, receipt, missing item and deadline. This prevents a sentence such as “the company reported it” from hiding whether the company only completed an internal form, reported a production-safety accident, or actually filed recognition with the social-insurance administrative department. It also prevents a clinician's diagnosis from being described as an insurance decision.

Accident report, medical diagnosis, occupational-disease diagnosis, work-injury recognition and disability assessment are five different records.

Match foreign identity and employment records before a deadline transaction

A foreign employee may have a passport, a newer replacement passport, a Chinese name, an employer-created transliteration, a Foreigner's Work Permit number, a residence document, a social-security number and one or more hospital patient numbers. Compare these before filing. Record the exact legal employer in the labor contract, payroll, work-permit and social-insurance records, and distinguish it from a client, host company, payroll vendor, overseas parent, dispatching company or office brand. A name mismatch does not determine entitlement, but it can block record retrieval, provider settlement or service of a decision.

Keep the original-language document and a careful Chinese translation when a counter cannot work from English. Ask whether the authority requires a translation, company seal, original, certified copy or an identity-update transaction. Do not rewrite an accident narrative simply to make the wording match. Preserve the earlier identifier and evidence of the change. If a bilateral social-security agreement is mentioned, request the exact agreement, covered branch, exemption certificate and valid period; nationality alone does not prove that work-injury insurance is exempt. If an app rejects a passport, use the official counter or authorised representative route rather than assuming the benefit is unavailable.

Build an evidence log without manufacturing a conclusion

Preserve contemporaneous material: messages assigning the task, shift or access records, photographs, machine or vehicle identifiers, witness names, first-aid records, ambulance records, hospital timestamps, diagnoses, invoices, leave certificates, employer notices and system receipts. Export electronic material with dates and context rather than circulating edited screenshots. Keep an untouched original and a working copy. For exposure cases, add job titles, dates, hazard names, protective equipment, workplace monitoring, occupational-health examination results and prior employers. Evidence should help an authority reconstruct facts; it should not be edited to assert a legal or medical conclusion that the evidence itself does not contain.

Ask witnesses to describe what they personally saw or heard, not whether the event was “definitely a work injury.” Ask clinicians to document the clinical history and findings accurately, not to decide employment causation outside their role. Ask the employer to preserve CCTV, access, equipment, safety and payroll records in writing and note the retention risk. If a record is incorrect, use the provider's or employer's formal correction process and retain both the original and correction trail. This website cannot assess causation, diagnose disease, grade disability or tell a person whether to accept a settlement; those questions require the responsible institutions and, where needed, qualified professional advice.
