Inguinal Hernia from Lifting at Work: Accident or Occupational Disease?

An inguinal hernia caused by physical strain reaches your ART (the compulsory workers' compensation insurer) through two different doors, and choosing the wrong one causes more rejections than anything else. If it appeared during a single sudden effort, it is a workplace accident. If it came from years of heavy lifting, it is a listed occupational disease — but only direct, mixed and femoral hernias are on that list. Indirect hernias are expressly excluded.

1. The two legal routes and which one is yours

An inguinal hernia is the protrusion of a loop of bowel or abdominal tissue through the inguinal canal, caused or aggravated by increased intra-abdominal pressure. The workers' compensation system recognises it by two separate routes, with evidentiary requirements that have nothing in common.

The workplace accident route

Article 6, subsection 1 of Law 24.557 defines an accident as "any sudden and violent event occurring by reason of or on the occasion of work". If your hernia appeared — or visibly worsened — in a single episode, lifting, pushing or carrying a specific weight on a given date, your case belongs here. You do not need to establish years of exposure: you need to prove the link between that one effort and the injury. That is why filing notice the same day, with the detail of what you lifted and how much it weighed, is worth more than any later report. On timing, see how long you have to notify the ART.

The listed occupational disease route

Decree 49/2014 added the risk agent "increased intra-abdominal pressure" to the Occupational Disease List, covering direct and mixed inguinal hernias and femoral hernias. The qualifying activities are "tasks whose ordinary performance requires physical load, dynamic or static, with increased intra-abdominal pressure when lifting, moving, shifting or pushing heavy objects".

Two concrete requirements. The limit values for weight and duration during the working day are those in Tables 1, 2 and 3 of Annex I to Ministry of Labour Resolution 295/03. And the period during which those tasks were performed may not be shorter than three years, continuous or discontinuous.

One temporal limit is worth noting: the decree itself states that the diseases it adds apply only to contingencies whose triggering event occurred after their inclusion in the list, that is, from 2014 onwards.

2. Direct, mixed, femoral and indirect: the decisive distinction

Not every inguinal hernia gets the same legal treatment, and this is almost never explained to the worker. A direct hernia passes through the posterior wall of the inguinal canal, generally through wall weakness associated with strain. A mixed hernia combines direct and indirect components. A femoral hernia emerges below the inguinal ligament. Those three are on the list.

The indirect hernia, which follows the inguinal canal and is often congenital in origin, was expressly excluded. That does not make it automatically uncompensable: if a specific, provable effort triggered or aggravated it, it is claimed through the workplace accident route of article 6, subsection 1.

A third, far less travelled door remains: the non-listed disease of article 6, paragraph 2(b). There you must file a reasoned petition with the Jurisdictional Medical Board, aimed at showing the concurrence of risk agents, exposure, clinical picture and activities with direct causal efficacy. The board hears you, the employer and the ART, takes evidence and rules on the basis of scientifically rigorous expert opinions; the Central Medical Board then has 30 days to confirm or overturn.

That is why the medical report you file must identify the hernia type precisely. Wrong framing leads the ART to reject a claim that, through the correct route, would have been accepted. If you also have spinal pathology from the same effort, see herniated disc and the ART.

3. When the ART claims a pre-existing condition with no pre-employment exam

The most common rejection is "pre-existing condition". The statute has an answer. Article 6, paragraph 3(b) of Law 24.557 excludes pre-existing impairments only where they are "established in the pre-employment medical examination". With no such examination, nothing is established.

Decree 49/2014 puts it even more plainly for this risk agent: pre-existing impairments at the start of the employment relationship must be established through the pre-employment examination; and where the examination was not carried out and the worker shows ordinary performance of tasks meeting the exposure conditions and limit values, "the causal connection with the work shall be presumed". That presumption is not absolute: it yields if the ART reliably establishes the congenital or non-work-related character of the condition, or the concurrence of non-work-related contributory factors, which are then disaggregated.

Watch that nuance, because it drives the final percentage. The common provisions of the same annex require the body determining the impairment to establish scientifically whether the injury was caused directly and immediately by the work, and that only work-attributable causal factors are compensated. Meanwhile, none of that suspends medical care or the wage-replacement benefit during Temporary Work Disability once the work's causal influence is shown. If you were rejected anyway, the route is in ART rejection of an accident or occupational disease.

4. How the sequela is rated and how the money is calculated

If a sequela remains after surgery — usually a mesh hernioplasty — the Medical Board fixes a permanent impairment percentage. Since 2 February 2026 that percentage no longer comes from the old schedule: Decree 549/2025 replaced Annex I of Decree 659/96 with a new impairment table, which rates the hernia within the Digestive System chapter, under "Abdominal Wall Injuries". Where more than one digestive sequela arises from the same contingency, the table combines them by the Remaining Capacity method rather than arithmetic addition.

The table applies "to every assessment or determination of work-related impairment not yet issued, regardless of the administrative or judicial stage it is at" (article 3 of the decree). Its application is not discretionary: article 9 of Law 26.773 requires administrative bodies and courts to align their reports, rulings and judgments with the schedule in force. The stated grounds of Decree 549/2025 recall that the Supreme Court has consistently held that deciding a Law 24.557 case without applying the schedule is an unequivocal departure from the statute.

Once the percentage is fixed, the money comes from article 14, paragraph 2(a) of Law 24.557, which applies where impairment is 50% or less:

53 × Monthly Base Income × impairment percentage × (65 ÷ age)

The Base Income is the monthly average of every wage accrued in the year before the first disabling manifestation, indexed month by month by the RIPTE wage index (article 12). The detail is in how ART compensation is calculated. On top of that result comes the 20% add-on of article 3 of Law 26.773 where the harm occurred at the workplace or while you were at the employer's disposal.

There is also a floor the SRT updates every six months: under article 2 of SRT Resolution 39/2026 (Official Gazette, 2 September 2026), between 1 September 2026 and 28 February 2027 compensation under article 14, paragraph 2 may not be lower than ARS 114,354,110 multiplied by the impairment percentage. You always receive the higher of formula or floor.

5. Step by step: from injury to payment

1. File notice the same day: tell the employer and the ART in writing, with as much detail of the effort as possible. What you lifted, how much it weighed, when the pain started, who was nearby.
2. Get treated through the ART: keep every report, prescription, the surgical record and the date of medical discharge.
3. If they reject you: you are entitled to a lawyer whose fees fall exclusively on the ART (article 1, Law 27.348) to open the file before the Jurisdictional Medical Board, a compulsory prior stage that excludes any other intervention. See how representation before the Medical Board works.
4. If you are discharged and pain or restriction remains: the medical discharge challenge is filed in person before the Medical Board with the accident notice and the discharge certificate (SRT Resolution 179/15, as amended by SRT Resolution 41/22).
5. If nobody requests the impairment determination: you can push it yourself from the 21st day counted from the day after Temporary Work Disability ends or treatment concludes.
6. The Medical Board has 60 administrative working days from the first properly completed filing, extendable for duly reasoned factual issues (article 3, Law 27.348). Once the deadline expires, the appeal route opens.
7. Settlement and payment: the Settlement Service may not approve a proposal for less than what strict application of the statute yields (Annex I, article 3). Sums are made available within five days of service of the approval (Annex I, article 4) and deposited into your payroll account (article 17). Article 4 of Law 26.773 also requires notice of the amounts within fifteen days.
8. If you disagree: you may appeal to the Central Medical Board or go straight to the labour court of the jurisdiction where the board sat (article 2, Law 27.348), with a court-appointed medical expert. Contingency-fee agreements are prohibited in those proceedings, and all evidence taken is free for the worker.

On the civil alternative: article 4 of Law 26.773 makes the election mutually exclusive and the systems do not stack. But article 5 clarifies that drawing the temporary disability benefit or receiving benefits in kind does not amount to an election. You can have the surgery and rehabilitation through the ART without burning the ordinary civil route.

6. Mistakes that weaken your claim

• Not reporting the single effort the same day: without that notice it becomes far harder to prove the sudden event article 6, subsection 1 requires.
• Assuming every inguinal hernia is covered: if it is indirect and there is neither a provable single effort nor three documented years of exposure, the ART has a legal basis to reject.
• Not obtaining a report stating the hernia type: direct, mixed, femoral or indirect changes the route and, with it, the evidence you have to produce.
• Attending the Medical Board without your own doctor: the insurer arrives with its own experts. Without representation, the percentage tends to land below the real one.
• Signing the discharge without recording persistent pain: that is the moment to document the sequela, before the file closes. See discharged with zero impairment.
• Not reconstructing the exposure: the listed route needs the actual weights and durations of your post, measured against the tables of Resolution 295/03.
