In short
Article 5 of Act 45-1935 sets a short clock: if the worker does not present to the doctor within the next five business days after the accident for treatment, nor satisfactorily explain the delay to the Administrator, the Administrator may deprive them of the right to receive compensation. Two things in the same text soften that blow. The first is that the delay can be explained, and when the worker proves it to satisfaction, the Administrator "shall be obliged" to pay the compensation and even the dietas for the time under treatment. The second is that what is lost is the compensation, not the treatment: the Act says the medical assistance the Administrator deems necessary to seek full recovery may not be denied under any circumstance. And Article 36 defines what counts as presenting: going to a Fund dispensary, or to a doctor, hospital or clinic under contract with the Fund, reporting at that appearance that you suffered a work accident.
What is it?
It is Article 5 of Act 45-1935, which governs the injured worker’s examination and medical treatment: the five-business-day window to present, the consequences of missing it, the right to bring your own doctor, the recourse to the Industrial Commission when assistance is inadequate, and the effect of refusing or opposing treatment, whose definition sits in Article 36.
Who can do it?
It applies to the worker injured or ill under the circumstances the Act covers, during the period of disablement. The duty to let oneself be treated and examined by a competent doctor designated by the Administrator, at appropriate times and places, runs through that period.

Step by step
Step 1: Count five business days from the accident
Article 5 puts it this way: if the worker does not present to the doctor "within the next five (5) business days after the occurrence of the accident for treatment, nor satisfactorily explain the delay to the Administrator, the latter may deprive them of the right to receive any compensation". Note the verb: "may". It is not automatic, and the same text opens the door of the explanation. But the clock starts the day of the accident, not the day the pain became serious.
Step 2: What counts as presenting — and the sentence you have to say
Article 36 defines the requirement: it is met "when the worker attends for treatment at a State Insurance Fund dispensary, or before a doctor, hospital or clinic under contract with that Fund when at that appearance they report having suffered a work accident". The last clause is the one that most often fails: going to a contracted emergency room and not saying it was a work accident is not the same as saying it. Say it, and ask that it be written down.
Step 3: If you missed it, explain the delay
The Act does not shut the door: it asks that the delay be satisfactorily explained to the Administrator. And it goes further, placing an obligation on the Fund: "when the worker has proven their delay to satisfaction, the Administrator shall be obliged to pay them the total compensation or the disability including the dietas for the time they were under medical treatment". That is, a proven explanation not only avoids the penalty: it restores payment for the period.
Step 4: Medical care cannot be denied to you
This is the sentence worth memorising. Even when the Administrator exercises the power to deprive you of compensation, "the medical assistance the Administrator deems necessary to seek the worker’s full recovery may not be denied to them under any circumstance". Compensation and treatment are two different things in this Act, and only one of the two is at stake when the deadline is argued.
Step 5: You may bring your own doctor to the examination
Article 5 gives the injured worker the right "to designate at their own expense a doctor or surgeon to be present at their examination or to give them treatment". The Act clarifies that this does not remove the Administrator-designated doctor’s right to visit you at the times they deem appropriate and under reasonable circumstances while you are unable to work. The two rights coexist: yours to have someone you trust present, and the Fund’s to examine you.
Step 6: If the assistance is inadequate, the Industrial Commission orders it
The same article carries the remedy: "if the Administrator does not provide adequate assistance to the worker, the latter may go to the Industrial Commission, which, after investigation by a doctor designated for the purpose, shall order the assistance the case requires and the Administrator shall comply with the Commission’s order". This is not an informal complaint: it is an order the Administrator complies with, preceded by a medical investigation by the Commission itself.
Step 7: Refusing or opposing treatment is broader than it sounds
Article 5 says that "the worker’s refusal or opposition without just cause to submit to the medical examination or treatment provided by the Administrator shall have the effect of depriving them of the right to receive compensation under this Act or to bring or continue proceedings" to obtain it. And Article 36 defines that refusal or opposition as "any voluntary act of the injured person that harms, hinders, prolongs or prevents the treatment provided to them, or that aggravates, or exposes to aggravation, their condition", expressly including disorderly or tumultuous conduct disturbing the hospital’s peace, acts of manifest immorality during hospitalisation making the patient’s stay undesirable, and manifest drunkenness during hospitalisation when it is a contraindication to the treatment, contributes to prolonging it, or comes with acts harming discipline or bothering other patients. Note the three words that protect you: "without just cause".
Where to do it
For treatment, at a State Insurance Fund Corporation dispensary or before a doctor, hospital or clinic under contract with the Fund, reporting right there that it was a work accident. If the assistance given is inadequate, the forum is the Industrial Commission, which investigates with its own doctor and orders.
How long it takes
What to do if something goes wrong
If the five days have passed, do not give the case up: the Act asks you to explain the delay and, if you prove it, obliges the Administrator to pay you even the dietas for the time under treatment. If you were seen at a contracted clinic but did not say it happened at work, tell the Fund as soon as possible and explain what happened, because Article 36 conditions the appearance on that report. If you are denied treatment over a compensation issue, the Act separates the two: necessary medical assistance cannot be denied under any circumstance. If the assistance is insufficient or delayed, the Industrial Commission can order what the case requires. And if you are accused of opposing treatment, the Act requires the refusal to be without just cause.
Common mistakes
- Counting the five days from when the pain worsened: the Act counts them from the occurrence of the accident.
- Going to a contracted clinic without reporting at that appearance that it was a work accident, which is what Article 36 requires for the visit to count.
- Believing that missing the deadline closes the case, when the Act admits a satisfactory explanation of the delay.
- Confusing losing compensation with losing treatment: necessary medical assistance cannot be denied under any circumstance.
- Putting up with inadequate assistance without going to the Industrial Commission, which investigates with its own doctor and orders.
- Not using the right to designate, at your own expense, a doctor to be present at the examination.
Frequently asked questions
How many days do I have to go to the Fund?
Five business days after the occurrence of the accident, for treatment. If you do not go and do not satisfactorily explain the delay, the Administrator may deprive you of the right to receive compensation.
Does going to a contracted hospital’s emergency room count?
Yes, under Article 36, if you attend for treatment before a doctor, hospital or clinic under contract with the Fund and at that appearance report having suffered a work accident. That report is part of the requirement.
I missed the five days. Have I lost everything?
The Act admits an explanation of the delay, and says that if you prove it to satisfaction the Administrator shall be obliged to pay you the compensation including the dietas for the time you were under medical treatment.
Can they take away my treatment?
No. Article 5 says the medical assistance the Administrator deems necessary to seek the worker’s full recovery may not be denied to them under any circumstance.
Can I bring my private doctor?
Yes. The injured worker has the right to designate, at their own expense, a doctor or surgeon to be present at their examination or to treat them, without affecting the Fund doctor’s right to visit them.
What counts as refusing treatment?
Article 36 defines it as any voluntary act of the injured person that harms, hinders, prolongs or prevents the treatment, or that aggravates or exposes their condition to aggravation, and includes disorderly conduct in the hospital, acts of manifest immorality during hospitalisation, and manifest drunkenness in the circumstances the article describes. The Act requires the refusal to be without just cause.
