- 2. What is Medical coding 1) Medical coding is classifying terms like medications, adverse events, medical history, disease conditions, diagnosis with reference to known standard terms. 2)Assigning a numerical code to clinical data using standard , approved dictionarist and guidelines.
- 3. Primary Objective of Medical coding To understand what is coding and why it is required To understand to be adhered to guidilines To understand methods of coding and coding process. To understand different types of dictionaries used in clinical research To understand about MedDRA and WHO-DD dictionaries To understand the common problems encountered while coding
- 4. Need for medical coding in general and Pharmacovigilance To classify similar verbatim text into predefined categories representing medical concepts for generation of statistical reports To ensure consistent data classification across all protocols globally across all projects To aggregate reported terms in medically meaningful groupings for the purpose of reviewing and summarizing safety data To report adverse event terms via individual case safety reports
- 5. Terms for which medical coding is done Following text items are coded l Adverse events(AE) e.g. Headache, Blurred vision l Concomitant medications e.g. Acetaminophen l Medical history e.g. Hypertension, Diabetes. l Surgical and investigational procedures: e.g. Angioplasty.
- 6. Minimum standards for medical coding To Select dictionaries that meets project and regulatory requirements To understand to be adhered to To understand methods of coding and coding process. To understand different types of dictionaries used in clinical research To understand about MedDRA and WHO-DD dictionaries To understand the common problems encountered while coding
- 7. Methods of medical coding 1)Auto encoding: Auto encoding is an electronic process which compares the text of the investigator term in the clinical trial database to the text strings stored in the dictionary databases 2) Manual Coding: Terms that are not coded by the auto encoder are coded manually by the medical coders using standard dictionaries
- 8. Dictionary category l Dictionaries are hierarchical code files l Dictionaries are of two types 1) Standardized dictionaries 2) Published classification systems
- 9. Standardized dictionaries 1) MedDRA(Medical dictionary for regulatory activities) 2) WHO(World health organization-Drug Dictionary) MedDRA: The terms that used to code from MedDRA are as follows: a) Signs and symptoms b) Diseases c) Diagnosis and therapeutic indication d) Surgical and medical procedures e) Medical history WHO DD: Study drugs, concomitant drugs are used to code
- 10. Published classification system 1) ICD-10-CM(International classification of diseases, ninth revision clinical modification) 2) WHO-ART(World health organization-Adverse Reactions terminology) 3) BNF(British National formulary) ICD-9-CM : The terms that used to code from MedDRA are as follows: a) Cause of death b) Medical History c) Concomitant illness d) Primary diagnosis e) Secondary diagnosis WHO-ART: Adverse events and serious adverse events BNF: Study drugs, concomitant drugs, previous drugs
- 11. MedDRA-Hierarchy SOC(System organ class):Cardiac disorders HLGT(High level group term):Coronary artery disorders HLT(High level term)-Ischemic coronary artery disease PT(Peferred term): Myocardial infraction LLT(Low level term): Heart attack
