01Principles and purposeThe professional or clinical skill and the decisions it supports.
Medical certification serves the bereaved, death registration, mortality statistics and public protection. The certifier must give the cause to the best of their knowledge and belief, based on records, clinical knowledge and available investigations. Certainty beyond reasonable clinical judgment is not required, but convenience, pressure to avoid referral or vague mechanisms must not replace an honest causal account.
Since the 2024 reforms in England and Wales, the attending practitioner discusses the proposed cause with an independent medical examiner. The examiner reviews relevant records, scrutinises the cause and offers the deceased’s representative a conversation. If the coroner does not investigate, the examiner signs the declaration and the office sends the MCCD to the registrar. A death certificate is issued by the registrar and is not the same document as the MCCD.
Key points
- In England and Wales, the statutory medical examiner system has applied since 9 September 2024. Every death not investigated by a coroner receives independent scrutiny by a medical examiner before registration.
- An attending practitioner with valid GMC registration and a licence to practise proposes the cause. Engage the medical examiner early; their role is scrutiny, discussion and communication, not transferring responsibility for honest certification.
- Notify the coroner when there is reason to suspect a violent or unnatural death, an unknown cause, or death in custody or other state detention, and follow the Notification of Deaths Regulations and local coroner process for other prescribed circumstances.
- On APC 1, for deaths after the first 28 days of life, Part 1 traces the immediate cause back to the initiating condition; Part 2 records other significant contributors. APC 2 uses a separate neonatal layout for a live-born child dying within the first 28 days.
- Avoid “cardiac arrest”, “natural causes” alone and organ failure without its cause. DHSC guidance makes a narrow exception for heart failure alone, though its underlying cause should be included when known. This does not make cardiac arrest an acceptable cause.
- The operational rules described here focus on England and Wales. Scotland and Northern Ireland use separate certification and investigation systems; use their current forms, statutory rules and local advice.
02Situations and prioritiesThe context, relevant information and actions that matter most.
The records and clinical course support a disease sequence from underlying condition to direct cause, with no prescribed circumstance requiring coroner notification. Draft the sequence, identify contributors and discuss it with the medical examiner.
If no disease or injury can be stated as the cause, do not use “natural causes” to complete the form. Notify the coroner, who decides whether investigation or post-mortem examination is required.
Trauma, poisoning, self-harm, neglect, exposure, treatment or procedure concerns, occupational disease or another external factor may bring the death within coronial jurisdiction. Provide all relevant facts and let the coroner determine whether the duty to investigate is engaged.
Concerns about care may require referral even when disease appears natural. Record and relay the concern without editing the causal account to avoid scrutiny; the medical examiner conversation gives representatives an independent route to raise concerns.
03Assessment and interpretationHow to gather information, assess the situation and recognise uncertainty.
Consider the information, its meaning and its limitations before deciding what follows.
- 01
Identity and eligibility check - Why
- Confirm the deceased, the practitioner’s attendance and authority to complete the relevant MCCD.
- Interpretation and limitations
- Use the current England-and-Wales definitions and form. If no attending practitioner can be found within a reasonable time, the death must be referred to the coroner rather than certified by an ineligible clinician.
- 02
Record and results review - Why
- Build the causal account from diagnoses, trajectory, procedures and investigations.
- Interpretation and limitations
- Use documented evidence and relevant pending results. Resolve conflicting diagnoses with the treating team or medical examiner; do not omit conditions or events merely because they may prompt referral.
- 03
Coroner notification screen - Why
- Identify statutory triggers and uncertain cases before completing certification.
- Interpretation and limitations
- Ask whether the cause is unknown, violent or unnatural, or the death occurred in custody or state detention, then apply all prescribed circumstances in the current regulations. Discuss uncertainty with the medical examiner and coroner service.
- 04
Causal sequence check - Why
- On the non-neonatal APC 1 form, distinguish the direct causal sequence from other significant contributing conditions.
- Interpretation and limitations
- Read Part 1 upwards to check that each condition could cause the condition above it; Part 2 contains contributors outside that chain. Use the separate APC 2 neonatal layout where applicable, with infant and maternal conditions recorded in their designated places.
04Worked approachesCases with ordered reasoning, an action and a check of the outcome.
01Worked casePneumonia after disabling strokeA patient with a recent large stroke, dysphagia and aspiration develops pneumonia and dies. Records support the sequence, with chronic diabetes contributing but outside it; no external event is suspected.+
- 1Review the timeline, imaging, swallowing assessment and clinical diagnosis, and confirm eligibility as an attending practitioner with a current licence to practise.
- 2Construct part 1 as the direct causal sequence, for example aspiration pneumonia due to dysphagia due to cerebral infarction, using specificity supported by the record.
- 3Place diabetes in part 2 only if it significantly contributed but did not form part of the direct sequence; do not add unrelated history.
- 4Final action: discuss the proposed cause and relevant care with the medical examiner, responding openly to questions and amending only when evidence supports it.
- 5Verification: after examiner scrutiny, confirm the office transmits the signed MCCD to the registrar and that the representative knows the next step.
02Referral approachDeath after a fall and fractureA frail patient dies weeks after a fall causing a fractured neck of femur, surgery and postoperative complications.+
- 1Trace the full sequence and recognise that an external injury may make the death unnatural even when chronic disease and complications also contributed.
- 2Notify or discuss with the coroner using the current local route, supplying the fall circumstances, treatment, complications and concerns without prejudging investigation.
- 3Do not omit the fracture or fall to keep the case on the medical route; the coroner decides whether the statutory duty to investigate is engaged.
- 4If returned for medical certification, agree the evidence-based sequence with the medical examiner and document the coroner’s decision and reference.
03Communication approachFamily questions the proposed causeThe representative says the proposed cause does not reflect a deterioration they repeatedly reported before death.+
- 1Listen without defensiveness, record the concern accurately and explain the distinct roles of attending practitioner, medical examiner and coroner.
- 2Alert the medical examiner before finalisation and provide the complete record, including communication and incident information relevant to scrutiny.
- 3Consider whether the concern creates a reason for coroner notification or a separate safety or candour process, obtaining senior advice where needed.
- 4Communicate what happens next without promising a particular cause or investigation; ensure the concern is not lost after registration.
05Feedback, follow-up and evidenceReview outcomes, seek feedback and identify what to improve.
- Track requests from the medical examiner and respond promptly so bereaved people are not exposed to avoidable delay; escalate missing records, unresolved identity or responsibility questions.
- Review returned or queried MCCDs for recurring errors in causal sequencing, vague terms, omitted external factors, abbreviations or inappropriate part 2 entries.
- Close the loop on pending microbiology, histology or toxicology that could materially alter the registered cause, using the medical examiner, registrar or coroner correction route.
- For professional evidence, document learning from one scrutinised case, focusing on causal reasoning, family communication and referral thresholds without identifiable details.
06Special situationsVariants, exceptions and circumstances that change the usual approach.
Scrutiny covers every non-coronial death
The statutory examiner system is universal for deaths in England and Wales that are not investigated by a coroner. It applies across hospital and community settings and includes an opportunity for the representative to ask questions.
Sequence is explanatory
APC 1 should explain how the initiating condition led to death, using the lowest completed Part 1 line for that initiating cause. The separate APC 2 form organises neonatal, maternal and other factors differently; select the correct form before constructing the account.
Referral is not an accusation
Notifying the coroner supplies facts so an independent judicial officer can decide whether investigation is required. A medical practitioner should not suppress uncertainty or an external factor to avoid perceived blame.
Jurisdiction changes the workflow
Medical examiner forms and the coroner pathway described here apply to England and Wales. Scotland uses the procurator fiscal and its certification review arrangements; Northern Ireland has a separate coroner and registration framework.
07Common pitfallsFrequent interpretation and management errors.
- 01
Confusing heart failure with cardiac arrest. The guidance accepts heart failure alone as a limited exception, with its cause added when known; terminal arrest remains an unacceptable stand-alone cause.
- 02
Using “natural causes” when the cause is unknown, or adjusting the sequence to avoid medical examiner questions or coroner notification.
- 03
Putting every comorbidity into part 1 instead of distinguishing the direct sequence from significant contributors in part 2.
- 04
Telling relatives that the MCCD is the death certificate, or giving firm registration timing before scrutiny and any coronial decision are complete.
