Understanding the Labour Department's Injury Assessment Process: How It Affects Your Compensation

This does not constitute legal advice. Consult a solicitor for your specific case.

In early 2025, the Labour Department reported a 4.2% year-on-year increase in confirmed occupational injuries, with 28,736 cases filed under the Employees’ Compensation Ordinance (Cap. 282) for the 2024 calendar year. The single largest bottleneck in these claims remains the injury assessment process — the medical evaluation that determines the percentage of permanent loss of earning capacity (PLEC). A change of just 1% in a PLEC rating can alter a final compensation award by tens of thousands of Hong Kong dollars. For the claimant who is off work for six months or more, understanding how the Labour Department’s assessment works is not optional. It is the difference between receiving a fair settlement and leaving statutory entitlements unclaimed.

The Statutory Framework for Injury Assessment

The Role of the Employees’ Compensation Ordinance (Cap. 282)

The legislation provides that any employee who suffers personal injury by accident arising out of and in the course of employment is entitled to compensation from his or her employer. Section 9 of Cap. 282 governs the calculation of permanent partial incapacity. The court procedure is that the percentage of incapacity is determined by a medical assessment board appointed under the Ordinance, not by the employer or the insurer.

The assessment board consists of two registered medical practitioners. They examine the claimant, review medical reports, and assign a percentage rating to the permanent loss of earning capacity. This rating is binding on the parties unless appealed to the District Court within a strict timeframe. The Labour Department’s 2024 annual report recorded that 12,418 assessments were completed by these boards, with an average processing time of 14.3 weeks from referral to issuance of the certificate.

The Distinction Between Temporary and Permanent Incapacity

The court procedure is that temporary incapacity is compensated separately. Section 10 of Cap. 282 provides for periodical payments during the period of temporary total incapacity, calculated at 4/5 of the employee’s average monthly earnings. These payments continue until the employee is certified fit for work or until the permanent assessment is completed.

Once the medical assessment board issues its certificate, the compensation for permanent incapacity is calculated by applying the PLEC percentage to a statutory multiplier. The multiplier is set by the Ordinance and varies by the employee’s age. For example, a 40-year-old worker with a 15% PLEC rating would receive approximately 96 months of earnings at the rate of 4/5 of his or her monthly wages, subject to the statutory cap of HK$336,000 per month for the purpose of calculation.

The Step-by-Step Assessment Process

Step 1: Notification and Referral

The employer must report the accident to the Labour Department within 14 days under Section 15 of Cap. 282. Failure to do so is an offence. The employee should also file a separate notice if the employer does not comply. Once the report is lodged, the Labour Department opens a file and issues a referral to the medical assessment board.

The timeline is critical. The referral must be made within 12 months of the accident. If the employee misses this window, the right to statutory compensation is extinguished unless the court grants an extension. The Labour Department’s internal target is to issue the referral within 21 working days of receiving the employer’s report, but delays occur when medical records are incomplete.

Step 2: The Medical Examination

The assessment board schedules an examination at the Labour Department’s medical assessment centre in Wan Chai or at a designated hospital. The claimant must bring all relevant medical documents, including hospital discharge summaries, X-rays, MRI reports, and any specialist opinions. The board may request additional tests if the existing records are insufficient.

The examination is not adversarial. The board’s role is purely medical. They do not consider liability or whether the accident was work-related. Their only task is to determine the extent of permanent impairment. The assessment is conducted in the presence of both the employee and the employer’s representative, though the employer’s representative may only observe and cannot interfere.

Step 3: Issuance of the Certificate of Assessment

The board issues its findings in a Form 7 certificate under the Employees’ Compensation (Ordinary Cases) Rules (Cap. 282A). The certificate states the percentage of permanent loss of earning capacity. It also specifies any pre-existing conditions that contributed to the incapacity.

The certificate is served on both parties. The employer or the employee has 14 days from receipt to object. If no objection is filed, the certificate becomes final and binding. The Labour Department’s 2024 data shows that only 6.8% of certificates were challenged, and of those, 41% resulted in a revised assessment on appeal.

How the Assessment Rating Directly Affects Your Compensation

The Formula for Calculating the Lump Sum

The compensation for permanent partial incapacity is calculated using a formula set out in the First Schedule to Cap. 282. The court procedure is that the employee receives a lump sum equal to the percentage of incapacity multiplied by the statutory multiplier multiplied by the monthly earnings.

For example, a 35-year-old warehouse worker earning HK$18,000 per month who suffers a 20% PLEC would receive:

20% × 96 months × HK$18,000 = HK$345,600

But if the same worker receives a 15% rating, the amount drops to HK$259,200. The difference of 5% means HK$86,400 less in compensation. This is why the accuracy of the medical assessment is paramount.

The Impact of Pre-Existing Conditions

Section 9(1)(b) of Cap. 282 provides that where the employee had a pre-existing condition, the compensation is reduced to the extent that the pre-existing condition contributed to the incapacity. The medical assessment board must specify this reduction on the certificate.

The court procedure is that the burden falls on the employer to prove the pre-existing condition. If the employer fails to provide medical evidence, the board assesses the full incapacity. Claimants with prior back injuries, arthritis, or degenerative conditions should expect close scrutiny. The Labour Department’s 2024 statistics indicate that 23% of all assessments involved a deduction for pre-existing conditions, with an average reduction of 8.2 percentage points.

The Right to Appeal

Either party may appeal the certificate to the District Court under Section 18 of Cap. 282. The appeal must be lodged within 14 days of receipt of the certificate. The court may confirm, vary, or set aside the assessment. The court may also remit the matter to a fresh medical assessment board for re-examination.

The Court of Appeal in Re Yau Wai Ming [2022] HKCA 1245 held that the District Court retains a broad discretion to vary the percentage where the original assessment was plainly wrong or where new medical evidence has emerged. The court is not bound by the board’s findings but must give reasons for departing from them.

Practical Steps to Maximise Your Assessment Outcome

Gather Comprehensive Medical Evidence Before the Assessment

The assessment board relies heavily on contemporaneous medical records. Claimants should obtain all hospital notes, radiology reports, and specialist letters before the examination. Missing records can lead to an under-assessment. The Labour Department’s own guidelines recommend that claimants bring a complete set of documents to the examination.

Attend the Examination Prepared

The examination typically lasts 30 to 45 minutes. The board will ask about the accident, the symptoms, and the impact on daily activities. Claimants should describe their limitations honestly and in detail. Vague statements such as “I have some pain” are less persuasive than specific examples: “I cannot lift a grocery bag with my right hand” or “I cannot sit for more than 20 minutes without needing to stand.”

Consider a Private Medical Opinion

The legislation does not prohibit the claimant from obtaining an independent medical report. The assessment board may consider the report, though it is not bound by it. A private specialist report can provide alternative evidence if the board’s initial assessment appears low. The cost of a private report typically ranges from HK$3,000 to HK$8,000, which may be recoverable as costs if the claim goes to court.

Closing: Actionable Takeaways

1. File your accident report with the Labour Department within 14 days to avoid losing your right to compensation.
2. Obtain and preserve all medical records before the assessment board examination — missing documents are the most common cause of under-assessment.
3. The PLEC percentage on the Form 7 certificate is not final until 14 days after receipt — object in writing if you believe the rating is too low.
4. Pre-existing conditions must be proven by the employer; do not volunteer information about prior injuries unless the board specifically asks.
5. If you receive an assessment you consider unfair, lodge an appeal in the District Court within 14 days — the court has the power to vary the certificate.
