What Is a Medical Reporting Organisation? A Plain-English Guide

 

A medical reporting organisation (MRO) sits between solicitors and medical experts in personal injury claims. It manages the instruction, coordinates the medical examination, and delivers the finished report back to the legal team.

For anyone new to personal injury or medico-legal work, the term can feel like industry jargon. This guide explains what an MRO does, why it exists, and how the role is regulated in England and Wales.

What Does a Medical Reporting Organisation Do?

An MRO acts as an intermediary. When a solicitor needs a medical report to support a personal injury claim, they can instruct an expert directly or go through an MRO.

The MRO handles the practical work:

• Sourcing a suitably qualified medical expert
• Booking the examination
• Managing communication between the claimant, expert, and solicitor
• Quality-checking the report before it reaches the legal team
• Issuing the invoice, which usually bundles the expert's fee with an agency fee

This structure saves solicitors time. Rather than searching for available experts case by case, they submit an instruction and the MRO takes it from there.

Why Do MROs Exist?

MROs became central to the personal injury sector after whiplash claims came under closer regulatory scrutiny. The government wanted to reduce the risk of solicitors and experts having financial relationships that could affect the independence of a medical report.

In response, the Ministry of Justice (MoJ) created MedCo, an online portal that randomly allocates medical experts for whiplash-related claims. The call for evidence that shaped this system identified a clear need for a formal definition of a medical reporting organisation. 

The Official Definition of an MRO

The MoJ defines an MRO, for MedCo registration purposes, as an organisation whose principal function is to provide medico-legal reporting services, and which is independent, properly staffed and resourced, and directly and solely responsible for handling instructions received through the MedCo portal.

That last point matters. The criteria specifically bar MROs from outsourcing their core functions to a parent company or third-party provider. An MRO that receives an instruction has to carry out the work itself, not simply forward it elsewhere for a fee.

The MoJ tightened this definition in 2016 to close a loophole that had allowed shell companies to register as MROs while passing the actual work to a linked organisation. The rule exists to stop clearing houses masquerading as fully functioning MROs.

MedCo Registration and Qualifying Criteria

Every MRO handling MedCo-portal work must go through a formal registration and audit process. Applicants must also hold a valid ICO registration number, which MedCo verifies against the Information Commissioner's Office register before approval.

New applicants are automatically treated as Regional, or Tier 2, MROs, since the Qualifying Criteria require a minimum of two years' trading history before an organisation can apply for High Volume National, or Tier 1, status. Tier 1 MROs offer national coverage; Tier 2 MROs typically operate regionally or serve a narrower specialism. MROs must also declare any direct financial links to law firms or claims management companies. This declaration exists to keep the appearance of independence intact, which is one of the qualifying tests under the MoJ criteria.

MRO Fees: What the Courts Have Said

MRO invoices typically combine two elements: the medical expert's own fee and the organisation's agency charge for coordinating the work. Historically, these two figures were often presented as a single lump sum, which made it difficult for the paying party to check that costs were reasonable.

A 2023 county court ruling addressed this directly. In Northampton General Hospital NHS Trust v Hoskin, the court found that a breakdown was needed to distinguish what had been paid to the consultant expert from what was retained by the MRO as an agency fee. The judge held that the relevant Civil Procedure Rules practice direction requires copies of the expert's own fee notes, alongside written evidence of any other disbursement claimed. In effect, MROs need to itemise their invoices clearly, and paying parties are entitled to ask for that breakdown.

MRO vs Direct Instruction: What's the Difference?

Solicitors can bypass an MRO and instruct an expert directly. Both routes are legitimate; the right choice depends on the case.

Using an MRO suits solicitors who:

• Handle high volumes of similar claims
• Want a single point of contact for scheduling and quality control
• Need access to a wide panel of experts across specialisms
• Prefer a bundled invoice rather than managing separate expert payments

Direct instruction suits solicitors who:

• Have an established relationship with a specific expert
• Are handling a complex or high-value claim requiring close oversight of the brief
• Want to avoid any additional agency fee on top of the expert's charge

Neither approach guarantees a better report. What matters is that the expert remains independent and that the report meets the requirements of CPR Part 35 and Practice Direction 35.

Who Uses Medical Reporting Organisations?

• Solicitors and insurers instructing reports for personal injury claims
• Medical experts (GPs, orthopaedic consultants, psychologists, and others) who join an MRO's panel to receive instructions
• Claims management companies referring cases into the legal process
• Defendant insurers, who may also request breakdowns of MRO invoices during cost assessment

The Bottom Line

A medical reporting organisation is a regulated intermediary, not just an admin layer. Its structure exists to protect the independence of medical evidence in personal injury claims, and its fees are increasingly subject to scrutiny in court.

Understanding how MROs are defined and regulated helps solicitors choose the right instruction route, and helps experts understand what a panel membership actually involves.

 FAQs

What does MRO stand for in a legal context?

MRO stands for medical reporting organisation. It refers to an intermediary that manages instructions for medical reports between solicitors and medical experts in personal injury claims.

Is an MRO the same as a medical expert?

No. An MRO coordinates the instruction and manages the process; the medical expert examines the claimant and writes the report. Courts have confirmed that an MRO's fees are not the same as an expert's fees.

Do all personal injury claims go through an MRO?

No. Solicitors can instruct experts directly. MROs are commonly used for whiplash and RTA claims processed through the MedCo portal, but direct instruction remains an option for other cases.

How is an MRO regulated?

MROs registering to use the MedCo portal must meet the MoJ's Qualifying Criteria, covering independence, staffing, financial transparency, and a ban on outsourcing core functions to third parties.

Can MROs’ fees be challenged?

Yes. Following the 2023 Hoskin ruling, paying parties can request an itemised breakdown separating the expert's fee from the MRO's agency charge.

Conclusion

A medical reporting organisation plays a defined regulatory role, not just an administrative one. Its structure exists to protect the independence of medical evidence in personal injury claims, and its fees are now open to greater scrutiny following recent case law.

For solicitors, understanding what a medical reporting organisation does, and how it's regulated, helps in choosing the right instruction route for each case. For experts, it clarifies what panel membership with an MRO actually involves. Either way, the term is worth understanding properly rather than treating it as background jargon.
