Complete guide to NHS clinical documentation in the UK — digital clinical records, clinical coding (ICD-10, OPCS-4), SNOMED CT terminology, PRSB record standards, discharge summaries, and documentation software.
NHS clinical documentation is going digital with SNOMED CT mandatory by 2026. Clinical coding accuracy affects hospital income — incorrect coding can cost £500K-2M per trust. This guide covers documentation standards and coding.

| ICD-10 | Disease classification for coding and reporting | All NHS trusts |
| OPCS-4 | Procedure classification for surgical coding | All NHS trusts |
| PRSB discharge summary | Standardised discharge summary structure | All NHS trusts |
| PRSB outpatient letter | Standardised outpatient letter structure | All NHS trusts |

Clinical Coding Process
- Documentation review: Clinical coder reviews medical record, operation notes, discharge summary
- Primary diagnosis: Identify the primary diagnosis (main reason for admission)
- Secondary diagnoses: Identify comorbidities and complications
- Procedure coding: Code all procedures using OPCS-4
- HRG grouping: Codes grouped into HRG for PbR payment
- CDS submission: Submit coded data via CDS to SUS
- Audit: Regular coding audit for accuracy and completeness
Discharge Summary Requirements (PRSB)
- Patient demographics: Name, NHS number, DOB, address
- Admission details: Date, reason for admission, admission method
- Diagnoses: Primary and secondary diagnoses (SNOMED CT coded)
- Procedures: All procedures performed (OPCS-4 coded)
- Clinical narrative: Summary of hospital course
- Medications: Discharge medications with changes highlighted
- Follow-up: Follow-up arrangements, GP actions required
- Pending results: Results not yet available at discharge
- Information given: Patient information and education provided
Frequently Asked Questions
- What is SNOMED CT and why is it mandatory?
- SNOMED CT (Systematized Nomenclature of Medicine Clinical Terms) is the mandatory clinical terminology for all NHS systems. It provides standardised codes for diagnoses, procedures, findings, and observations. SNOMED CT enables interoperability, analytics, and consistent coding. All NHS EPRs must use SNOMED CT by 2026.
- What is clinical coding in the NHS?
- Clinical coding translates clinical diagnoses and procedures into ICD-10 (diagnoses) and OPCS-4 (procedures) codes for PbR payment, SUS submissions, and national datasets. Clinical coders review medical records and assign codes. Coding accuracy affects hospital income — incorrect coding can cost £500K-2M per trust.
- What are PRSB record standards?
- PRSB (Professional Record Standards Body) defines standards for clinical records — discharge summary, outpatient letter, referral letter, clinic letter, diagnostic report, and care plan. PRSB standards ensure records are structured, consistent, and interoperable. All NHS EPRs must meet PRSB standards.
