Why ACC Declines Claims

Many people are surprised when ACC declines a claim, particularly when they have experienced pain, injury, or disruption to their ability to work.

However, ACC must apply the legal criteria contained in the Accident Compensation Act 2001 when deciding whether a claim should be accepted.

If ACC determines that those legal requirements are not met, the claim may be declined.

Understanding the most common reasons why ACC declines claims can help clarify how the decision-making process works.

ACC Must Apply Legal Criteria

ACC operates under legislation and cannot approve claims unless the injury meets the legal definition of cover under the Accident Compensation Act 2001.

For cover to be accepted, ACC must generally be satisfied that:

• A Personal Injury Exists
• The Injury Was Caused By An Accident Or Another Covered Event
• The Diagnosis Is Supported By Medical Evidence
• The Injury Is Not Better Explained By Non-Accident Causes

If ACC determines that one or more of these requirements are not met, the claim may be declined.

Reason 1 – ACC Does Not Consider The Injury To Be Caused By An Accident

One of the most common reasons ACC declines claims is because ACC determines that the injury was not caused by an accident event.

Under the ACC scheme, an accident usually involves a sudden external event that results in injury.

Examples may include:

• Slips Or Falls
• Workplace Incidents
• Sports Injuries
• Motor Vehicle Accidents

If ACC determines that the symptoms developed without a clear accident event, cover may be declined.

Reason 2 – Degeneration Rather Than Accident

ACC may decline a claim if the symptoms are considered more likely to be caused by degeneration rather than by an accident.

Degeneration refers to changes in the body that occur naturally over time.

Examples may include:

• Degenerative Disc Changes In The Spine
• Age-Related Joint Changes
• Osteoarthritis

In situations where medical imaging shows degenerative changes, ACC may determine that the symptoms are related to those changes rather than to the accident described in the claim.

Reason 3 – Insufficient Medical Evidence

Medical evidence plays a central role in ACC cover decisions.

ACC may decline a claim if the available medical information does not clearly support the diagnosis or the cause of the injury.

Examples may include situations where:

• The Diagnosis Is Unclear
• Medical Records Do Not Describe An Accident Event
• Clinical Findings Do Not Support The Claimed Injury

In these situations ACC may determine that the legal criteria for cover have not been satisfied.

Reason 4 – The Injury Developed Gradually

ACC may decline claims where symptoms developed gradually rather than as a result of a sudden accident.

Some gradual conditions may still be covered if they meet the criteria for a work-related gradual process injury.

Examples may include:

• Occupational Hearing Loss
• Repetitive Strain Injuries
• Diseases Caused By Workplace Exposure

However, if the condition does not meet the legal criteria for a gradual process claim, ACC may decline cover.

Reason 5 – The Symptoms Are Considered A Health Condition Rather Than An Injury

ACC covers personal injuries rather than general health conditions.

In some situations, ACC may determine that the symptoms described in the claim are related to illness or disease rather than to an injury caused by an accident.

Examples may include:

• Medical Conditions That Develop Naturally Over Time
• Illnesses Not Caused By An Accident
• Symptoms Without Evidence Of Physical Injury

When this occurs, ACC may conclude that the claim does not meet the legal definition of personal injury.

What Happens When ACC Declines A Claim

When ACC declines a claim, it means cover has not been accepted.

Because entitlements depend on cover being accepted, a declined claim means the claimant does not have the right to access ACC entitlements.

These entitlements may include:

• Treatment Support
• Weekly Compensation
• Rehabilitation Services
• Lump Sum Compensation For Permanent Impairment

However, in some situations claimants may choose to explore whether additional medical evidence may clarify the cause of the injury.
