Route Map
Distinguish Common Illness, Accidents, Occupational Disease, Special Situations, Mutua, Relapse, and Return
Classify the cause and decision maker because payment and review rules change.
Classify the contingency
Common illness and non-work accident use the public-health and common-contingency route. A work accident or occupational disease is a professional contingency and can involve the employer's collaborating mutua. The label affects regulatory base, payment start, evidence, healthcare management, possible benefit surcharge for safety failures, and review. A commuting or remote-work event can still require a fact-specific professional assessment.
The Social Security temporary-incapacity overview also separates special situations. Secondary disabling menstruation starts benefit from day one under its own 60 and 75 percent sequence. Pregnancy interruption and the first day of week 39 of pregnancy use first-day salary followed by the statutory percentages. Qualifying organ or tissue donation pays 100 percent of the regulatory base from day one. These are not generic paid leave labels and require the competent medical process.
Identify the decision makers
The public health service, mutua, INSS or ISM can have roles depending on cause, stage and scheme. The clinician certifies inability and review through the official medical system. The employer receives administrative information needed for work and payroll, not the full diagnosis. The mutua can call the worker to reviews in managed cases. INSS determines benefit and contingency questions and becomes the exclusive medical-control body after 365 days.
A relapse within the statutory relationship to a prior process can count toward the same duration rather than resetting every clock. Obtain the actual classification. A return follows an effective alta, not an employer's informal view that the worker looks recovered. Continued limitations after return can require prevention review, reasonable accommodation, gradual measures or a separate permanent-incapacity assessment.
Use ordinary healthcare for common cases, urgent care for emergencies, the mutua or accident protocol for suspected work causes, contingency determination when classification is disputed, and the decision-specific alta review route. A worker well enough to work without medical incapacity should use treatment or workplace adjustment rather than seek IT only as conflict protection.
Eligibility
Check Registration, Contribution History, Medical Certification, Cause, Work Status, and Continuing Eligibility
Test benefit conditions separately from the clinical need for care.
Check insured status and contributions
The worker normally must be affiliated and in alta or an assimilated situation when incapacity begins. Common illness generally requires 180 contribution days in the preceding five years. Accident, whether work-related or not, and occupational disease do not require a prior contribution period. Special situations have their own conditions. Verify the exact scheme and record rather than relying on months with an employer.
Nationality does not create a different benefit percentage. A Spanish, EU or third-country employee uses the insured employment rules, while immigration permission and absence from work remain separate issues. A student who is genuinely employed can qualify through that employment. A person receiving unemployment, changing jobs, working abroad or with multiple employers needs case-specific coordination.
Confirm medical and work incapacity
Treatment alone is not a baja. The competent clinician assesses whether the condition temporarily prevents the usual work and issues the official record. Describe duties, schedule, exposures and functional limitations accurately. A diagnosis may disable one occupation but not another. Working while officially incapacitated can conflict with recovery and benefit duties, though any compatibility question requires formal advice rather than assumption.
For a suspected work accident or occupational disease, report when, where, how and under whose instruction it occurred. Preserve workplace evidence. A mutua disagreement does not convert the facts; the worker can seek public care where needed and request formal contingency determination.
Separate employee and self-employed administration
Employees commonly receive delegated payment through payroll before direct-payment transitions. The employer, mutua or INSS role depends on days and contingency. A self-employed claimant must use the RETA procedure, identify the managing entity, satisfy current contribution and activity declarations, and remain aware of continuing contribution rules.
Confirm eligibility with INSS, ISM or the responsible mutua using the exact current facts. Do not pay an intermediary for a guaranteed baja. Public clinical and benefit decisions cannot lawfully be bought, and a private certificate does not automatically replace the official Social Security medical process.
Evidence
Preserve Medical Status, Employer Notice, Accident Evidence, Mutua Reviews, Payroll, and Foreign Certificates
Prove incapacity and administration without exposing unnecessary clinical detail.
Preserve official medical dates
Record the baja date, contingency, estimated duration, next review, clinician or body, and later confirmation or alta. Since administrative transmission is electronic, the worker generally does not carry paper medical parts between doctor and employer, but must still follow the employer's lawful absence-notice process. Verify that payroll and the employer received the correct administrative status. Do not email a diagnosis or complete medical history unless a defined professional process requires it.
Keep appointment notices, attendance proof, medical reports, prescriptions, tests, treatment and functional restrictions for the managing body or appeal. A missed mutua or INSS review can suspend or end payment, so preserve notice delivery and any documented serious reason for nonattendance. Request accessible appointment or communication adjustments early.
Build the workplace file
Keep contract, role, schedule, payroll, prior-month contribution base, convenio top-up clause, alta and work-life record. For a work event, record time, location, task, instruction, equipment, witnesses, hazard, immediate report, medical attendance and employer or mutua accident documentation. Preserve photos or messages lawfully without taking unrelated confidential data.
If the employer denies notice, use dated email, portal receipt or witness. If a foreign certificate covers an illness arising abroad, contact the responsible Spanish authority and employer immediately about accepted form, translation, verification and deadlines. A foreign certificate can be evidence but does not automatically dictate Spanish benefit status. Keep originals and submit copies unless expressly required.
Reconcile every system
Compare identity, Social Security number, employer, contingency, dates and bases across health, mutua, INSS, payroll and Importass. Download the Importass contribution-base report, which can reveal a missing or incorrect declared base but does not replace the benefit decision, and preserve monthly payroll separately.
Create a chronology and evidence index for any gap, wrong contingency, missing payment or alta dispute. Redact unrelated medical details from employer-facing material. Provide full clinical evidence only to authorised health, prevention, benefit or court professionals under secure channels.
Action Steps
Seek Care, Notify Work, Attend Reviews, Verify Pay, Resolve Contingency, and Coordinate Return
Complete clinical, work, benefit, and payroll actions in the correct order.
Follow the sequence
-
Seek appropriate care. Use emergency care for immediate danger, the public clinician for common incapacity, and the workplace or mutua accident route where a professional cause is suspected.
-
Describe work and function. Give accurate duties, exposure, dates and limitations. Do not ask a clinician to solve an employment dispute through false certification.
-
Verify the official baja. Record cause, start, estimated duration and next review. Correct identity or employer errors promptly.
-
Notify the employer. Follow the lawful absence channel and timing. State inability and administrative status without volunteering diagnosis. Save delivery proof.
-
Preserve accident evidence. Report a work event, identify witnesses and obtain employer and mutua records. Seek necessary care even if classification is disputed.
-
Attend reviews and treatment. Monitor public health, mutua, INSS or ISM appointments. Request rearrangement immediately with evidence if attendance is genuinely impossible.
-
Audit payroll. Compare benefit days, regulatory base, percentage, payer and convenio top-up with the nómina and bank. Ask for itemised correction.
-
Request contingency determination when needed. The worker can initiate the formal INSS procedure with medical and employment evidence. A general complaint is not the decision.
-
Respond to alta or extension decisions. Use the exact review or disconformity route and deadline shown, because mutua professional alta, INSS 365-day alta and ordinary decisions differ.
-
Coordinate return. Return on the effective date unless a valid review procedure has a different effect. Ask prevention services for restrictions, adjustments or safe reintegration. Document any refusal.
After return, confirm payroll, contribution and holiday corrections. Update benefit, unemployment or immigration bodies only where the status change affects them. If long-term impairment remains, obtain advice on accommodation, rehabilitation or permanent incapacity rather than staying absent without valid certification. Keep the return date, restrictions, contact person and agreed follow-up in writing.
Pay and Cost
Calculate the Regulatory Base, Day-by-Day Percentage, Payer, Convenio Top-Up, and Self-Employed Cost
Price the absence from the correct prior base and contingency.
Apply the statutory sequence
For common illness and non-work accident, the statutory benefit is normally 60 percent of the regulatory base from day 4 through day 20 and 75 percent from day 21. The first three days have no statutory Social Security benefit unless the convenio or employer improves them. In the ordinary employee sequence, the employer bears days 4 to 15 and delegated payment then follows through the responsible system, subject to the actual case.
For work accident and occupational disease, the employer pays full salary for the day of the event or baja and benefit is generally 75 percent of the professional-contingency regulatory base from the following day. The official amount page provides the current special percentages for menstruation, pregnancy interruption, week 39 and organ donation.
Calculate the base carefully
For an ordinary monthly-paid common case, the daily regulatory base generally derives from the prior month's common-contingency contribution base divided by 30. Daily pay, new employment, multiple jobs, part time, professional contingency, overtime and special schemes require their own calculation. Compare the payslip base with Importass and challenge under-contribution.
Read the applicable convenio for a top-up to a higher percentage, first-day cover, hospitalisation or occupational rules. A contractual top-up is separate from statutory benefit and can have conditions. Net payment also reflects tax and contributions.
Budget gaps and administration
Costs can include transport to reviews, medicines, treatment gaps, translation of foreign certificates, professional reports, union or adviser help and delayed-payment cash flow. Official clinical, INSS and mutua procedures are free. Self-employed workers must budget the statutory benefit against continuing or adjusted contribution obligations and possible direct-payment administration.
If delegated payment fails, investigate employer payroll, managing entity and direct-payment eligibility rather than buying an expedited service. Ask for written calculation and payer dates. Never pay an agent who guarantees certification, a higher contingency or an appeal result.
Deadlines
Track Immediate Notice, Reviews, 365 Days, Extension, Payment Change, Holiday, Return, and Appeals
One missed medical or review clock can change both absence and payment.
Control the early calendar
Notify the employer as soon as the absence and expected status are known, following workplace rules. Attend clinician, mutua, INSS or ISM reviews on the stated date. Open electronic and postal notices. A missed review without justified evidence can suspend or end benefit. Track confirmation and estimated-duration dates rather than assuming the original baja lasts indefinitely.
Payroll changes by contingency and day. Record the move from employer liability or delegated payment to later payer stages and any direct-payment application. Preserve every month because corrections can affect contributions and tax.
Understand the 365-day point
Temporary incapacity normally runs up to 365 days. If no alta is issued at exhaustion, the current system can move automatically into a possible extension up to 180 further days where recovery is expected. INSS or ISM has exclusive medical control after 365 days and can issue alta or initiate permanent-incapacity assessment. Do not wait for the employer to explain the legal effect.
The official forms directory separates INSS alta disagreement, mutua professional-contingency alta review, relapse and contingency requests. Some routes use very short business-day periods. File the exact form, decision and evidence, retain the receipt, and verify whether the filing maintains incapacity or requires return.
Protect employment transitions
An alta states the effective return date. Coordinate schedule, equipment and prevention measures before then. If new symptoms arise, seek medical review rather than remain absent informally. Holiday overlapping IT can often be taken later under statutory conditions; agree and document new dates.
A dismissal, contract end, unemployment transition, job change or departure can change payer and benefit interaction but does not automatically erase IT. Employment challenges have separate short deadlines. A benefit complaint, medical review or internal discussion does not automatically suspend dismissal action. Maintain an integrated calendar for medical status, payment, holiday, employer action, immigration and social-court remedies.
Problems and Help
Resolve Certificate Gaps, Missed Reviews, Work During IT, Wrong Contingency, Dismissal, Payment Error, and Alta Disputes
Use the specialist medical or benefit remedy while preserving employment claims.
Fix the exact failure
For a certificate or date gap, contact the issuing health body immediately, preserve appointment and system evidence, notify the employer and obtain advice before working or remaining absent. For a missed review, submit the notice and serious documented reason through the stated channel without delay. For a payment error, build a day-by-day calculation with contingency, regulatory base, percentage, payer, convenio top-up, payroll and bank proof.
Working during IT, travelling contrary to recovery, refusing treatment or missing reviews can jeopardise benefit, but rules are fact-specific. Ask the managing body before compatible activity rather than relying on employer permission or social media.
Separate disputes
If common and professional cause is disputed, request INSS contingency determination with medical, accident and work evidence. If a mutua issues professional-contingency alta before 365 days, use its special review. If INSS issues alta after 365 days, use the separate disconformity route. A generic mutua complaint or ordinary administrative letter does not replace either.
Dismissal during IT is not automatically valid or invalid. Test the stated cause, evidence, disability or health discrimination, retaliation, procedure and timing. Preserve the termination delivery date and use the social-court framework within the employment deadline while the benefit dispute proceeds. Inspectorate can address pressure to work, unregistered employment or safety breaches but does not decide every dismissal or payment claim.
Escalate urgent cases
Immediate health danger, forced unsafe return, violence, coercion or withheld identity requires emergency, prevention, police or specialist help as appropriate. Use union or worker representatives, mutua complaint service, INSS information, health-service patient support, Inspectorate, legal aid and qualified labour or Social Security advice.
Professional help is proportionate for a work-cause dispute, safety surcharge, complex base, long duration, permanent-incapacity transition, dismissal, missing payment, short alta-review deadline or immigration interaction. Bring the decision, full chronology, medical and work evidence index, payroll, bases, appointments, desired remedy and earliest deadline.
