ObstetricsThe hospital department label commonly used for maternity care; it identifies a service route and does not determine an individual care plan.Obstetrics departmentThe pregnancy, childbirth and postpartum clinical route within an institution; its administrative journey continues in the separate maternity and newborn administration center.Occupational-disease diagnosisA diagnosis made through a legally qualified occupational-disease route using occupational history, exposure and medical evidence; work-injury recognition is a separate administrative step.Occupational-health examinationA qualified occupational-health examination linked to stated occupational exposure and timing; it is not an ordinary check-up, occupational-disease diagnosis or work-injury decision.Online clinician authenticationThe institution's real-name control and displayed electronic professional credentials for the person providing the online service; a profile photo or marketplace badge is not enough.Online consultation appointmentA provider-issued booking for a named online service, patient identity, department, format and time; it does not guarantee clinical eligibility, prescription or completion.Online consultation process recordThe text, image, audio or video material retained by the accountable institution for an online encounter under the applicable minimum period; it is not always a patient-downloadable file.Online first visitA direct-to-patient internet encounter without a qualifying prior diagnosis for that issue; it is generally outside the national model except for specifically approved limited pilots.Online follow-upAn internet diagnosis encounter considered only after prior records show a clear diagnosis and the receiving physician decides the current visit meets the follow-up conditions.Online follow-up eligibilityThe receiving physician's decision on whether prior records and the current encounter meet the regulated follow-up boundary; registration or document upload alone does not decide it.Online pharmacyA licensed online drug seller that must follow identity, prescription, pharmacist and transaction-record rules.Online real-name registrationThe patient-account process linking truthful identity information to the online encounter; national rules do not guarantee every platform accepts a foreign passport or phone number.Online-to-offline handoffThe documented connection from a stopped or completed online encounter to the exact physical institution, campus, department, appointment and record needed for the next step.Ophthalmic medical-service price itemA nationally organized eye-care service-project category implemented through provincial and local price rules; it is not one nationwide patient price or insurance benefit.Ophthalmology departmentThe medical department responsible for eye diagnosis and treatment within its registered scope; the department name does not identify the right visit or classify urgency online.Optical prescriptionA responsible provider's dated written optical parameters and context, kept separate from an eyeglasses or contact-lens order and never interpreted by this glossary.Optical shopA commercial eyeglasses or optical-product route whose business identity, trained staff, measuring equipment, order, receipt and after-sales terms require verification.Oral and maxillofacial surgeryA provider-defined specialist department whose referral, campus, appointment and service scope must be confirmed without using the label for online symptom triage.Orthodontic applianceA provider-prescribed individualized product whose identity, supply, replacement and continuing-care plan must be confirmed by the responsible dental team.Orthodontic record packThe originating provider's available plan, visit history, images, scans or models, appliance information, payment record and handoff note for a receiving orthodontic service.Orthokeratology fitting recordThe medical institution's one-person fitting file containing provider-controlled assessment, consent, lens information and follow-up records; it is not a self-use guide.Orthokeratology lens (OK lens)A registered medical-device product fitted through a qualifying medical institution and responsible ophthalmology team; this term does not establish suitability or instructions.OTC medicineA non-prescription product identified by the regulated OTC mark; OTC does not mean suitable for every person.Outbound visa medical formA destination, consulate, employer or school form whose current edition, required issuer, fields, language, validity and submission route must be confirmed before booking an examination.Outpatient careCare provided without inpatient admission, normally through a registration route.Outpatient chronic and special-disease benefitA locally administered basic-medical-insurance benefit for a recognised disease;

it can change independently of the building's hours.Outpatient special-disease benefit recognitionThe insured-place decision that a participant meets the current local disease and evidence standard; a clinical diagnosis or prescription does not create it automatically.Outpatient special-disease benefit renewalThe local review and recording process used before or after a stated expiry; submission does not prove the renewed status is active.Outpatient special-disease benefit validityThe period recorded for a recognised benefit, kept separate from insurance entitlement, prescription validity, clinical follow-up and provider-selection periods.Outpatient special-disease manual reimbursementA document-based fallback permitted by the insured place for qualifying self-paid expenses; self-payment or a failed terminal does not guarantee approval.Outpatient special-disease provider selectionThe recorded choice of one or more qualified treatment institutions where the local disease route requires it; an appointment or referral does not update the selection.Outpatient special-disease recognition institutionA medical institution currently authorised to assess and record recognition for an exact disease; general medical-insurance designation does not prove this function.Outpatient special-disease treatment institutionA provider qualified and, where required, selected for treatment under the recognised benefit; recognition authority and treatment capability may differ.Outside medical recordsRecords issued by another provider that a receiving hospital may verify for source, completeness, security, language and format before use.Overseas physical-examination validationReview of an overseas examination form and supporting original reports by the responsible China route; missing or unacceptable items may require local examination.Overseas vaccination historySource records issued outside China and presented unchanged to the responsible provider for professional review; a translation or family summary does not convert them into a Chinese record.
Need the complete adult-vaccination or travel-health route?
The adult vaccination and travel health center separates clinic access, domestic records, International Travel Health Care Centers, ICVPs, border checks, destination requirements and outbound medical forms. It does not recommend a vaccine or confirm one journey’s live requirement.
Need the complete diagnostic-service route?
The diagnostic tests, imaging and pathology center connects provider checks, orders, identity, costs, reports, image data, pathology material and clinician-led follow-up. It does not choose a test or interpret a result.
