Read Codes are a coded thesaurus of clinical terms and have been used in the NHS since 1985.

What does "coded" mean in the above?

Simply stated, a code is a set of symbols understood by a group but not necessarily by outsiders. Doctors have code words for various symptoms and ailments. You can do a google search and read many blogs telling all about it. Apparently a medical practitioner named James Read from England developed the first set of codes. Also, see the "thefreedictionary" medical dictionary of "read code"

Let me first try to explain the necessity and development of Read Codes before I touch upon the meaning of "coded".

Prior to the 1980s, no suitable coding schemes could be found for large parts of patient history, examination findings, preventive care, administrative procedures,laboratory and imaging findings and so on. During the early 1980s Dr James Read developed specific coding schemes for all these areas. The term "coded" is used because each clinical term is assigned a code. Read Codes are a comprehensive list of clinical terms intended for use by healthcare professionals to describe the care and treatment given to patients. Read codes support detailed clinical encoding of multiple patient phenomena including: occupation; social circumstances; ethnicity and religion; clinical signs, symptoms and observations; laboratory tests and results; diagnoses; diagnostic, therapeutic or surgical procedures performed; and a variety of administrative items (e.g. whether a screening recall has been sent and by what communication modality, or whether an item of service fee has been claimed). So, Read Codes are an excellent coding system available to capture a complete medical record, which can be used for audit, analysis and research. They allow coding of all diagnoses, procedures, drugs and administration. The most important use of clinical coding is in the creation of an electronic patient record (EPR).

In 1990, the NHS purchased the Read Codes from Dr James Read and made them the UK standard coding system for the NHS. The NHS then decided to expand the codes to cover all areas of clinical practice to include physiotherapy, nursing and health visiting, and commissioned the Clinical Terms Project. This led to the production of Version 3 Read Codes. Version 2 of Read Codes had approximately 105,000 codes, and version 3 has approximately 270,000 codes. Read Codes are the predecessors of SNOMED CT. Systematized Nomenclature For Medicine – Clinical Terms (SNOMED CT) is a merger of Clinical Terms Version 3 of Read Codes with SNOMED RT – the original SNOMED reference terminology developed by the American College of Pathologists. SNOMED CT is an attempt to produce a worldwide system of clinical coding to enable the development of a complete electronic health record. It covers not only medicine but also veterinary practice.

The coding in the Read Clinical Classification has four-digit alpha-numeric codes using the numerals 0–9 and the letters A–Z. To give an example of coding, "Rubella + pregnancy" is coded as "K2A3". The structure of Read codes allows almost anything to be coded in the computer record. Entering data need to be very specific about coding structure to allow complete and accurate database search results. Chapters A–Q of Read Codes contain diagnostic codes, with chapter R (Symptoms, signs and ill-defined conditions) having codes for “symptomatic” diagnoses. As known to me, the numbers and letters of Read Codes are based on the undermentioned codes:

Numbers: History and symptoms 1; Examination and signs 2; Diagnostic procedures 3; Laboratory procedures 4; Radiology and physics in medicine 5; Preventive procedures 6; Operations, procedures, sites 7; Other therapeutic procedures 8; Administration 9

Letters: Infectious and parasitic diseases A; Neoplasms B; Endocrine, nutritional, metabolic and immunity disorders C; Diseases of blood and blood-forming organs D; Mental disorders E; Nervous system and sense organ diseases F; Circulatory system diseases G; Respiratory system diseases H; Digestive system diseases J; Genitourinary system diseases K; Complications of pregnancy, childbirth and the puerperium L; Skin/subcutaneous tissue diseases M; Musculoskeletal and connective tissue diseases N; Congenital anomalies P; Perinatal conditions Q; Symptoms, signs and ill-defined conditions [D] R; Injury and poisoning S; Causes of injury and poisoning T; External causes of morbidity and mortality U and Unspecified conditions Z.

I hope, I have been successful in giving you an idea of what "coded" signifies in the thesaurus of Read Codes.
