Disease relevance of International Classification of Diseases

• OBJECTIVE: To assess the validity of the use of International Classification of Diseases, Ninth Revision, Clinical Modification (ICD) codes to identify hospitalizations with clinical evidence of an episode of acute CHF in data of The Corpus Christi Heart Project, a population-based surveillance program for hospitalized coronary heart disease [1].
• Accuracy of ICD codes 430 to 438.9 (n=678) revealed the highest proportion of incident strokes identified by the acute stroke diagnoses (ICD-9 codes 430, 431, 434, and 436) [2].
• There were claims for migraine drugs (ICD-9 code for triptans or ergot compounds) for just 140 (11.1%) SM and 34 (2.7%) PM sufferers, and migraine analgesics (butalbital and isomethepthene compounds), for 6.3% SM and 2.2% PM sufferers (0.7% of the controls) [3].
• As alcohol abuse has been implicated in rosacea, and alcohol can confound symptoms of depression, an "Alcohol" variable was created by grouping all ICD-9-CM codes related to alcohol dependence and abuse (codes 303, 303.0, 303.9 and 305.0) [4].
• Nearly all (96%) of the 445 matched incident cases in 1994 had claims data (CPT, DRG, or ICD-9 code) indicative of breast cancer [5].

Biological context of International Classification of Diseases

• METHODS: We used the General Practice Research Database (GPRD) to describe DMARD use by patients with RA identified using ICD-9 codes [21].
• METHODS: Eighteen children with a refined phenotype of ADHD, who also met ICD-10 criteria for hyperkinetic disorder (mean age 10.4 years), and 16 normal children (mean age 10.3 years) were compared using magnetic resonance imaging [22].
• SUBJECTS AND METHODS: Fifty-one alcohol-dependent smokers and 327 non-alcohol-dependent smokers diagnosed as ICD-10 and DSM-IV-nicotine dependent, were investigated by means of the Fagerström Test for Nicotine Dependence, the Lübeck Craving-Recurrence Risk Questionnaire and the Lesch Alcohol Dependence Typology (both adapted to smoking) [23].
• Bone mineral density (BMD) testing, diagnosis of osteoporosis, and treatment with any Food and Drug Administration-approved medication for osteoporosis were identified using CPT, ICD-9, and National Drug Codes for the 6-month post-fracture period [24].

Associations of International Classification of Diseases with chemical compounds

• Should caffeine abuse, dependence, or withdrawal be added to DSM-IV and ICD-10 [25]?
• Recent hemiplegic patients (<3 months) suffering from major depressive disorder (determined by International Classification of Diseases, 10th Revision, and Montgomery-Asberg Depression Rating Scale [MADRS] >19) were randomized to receive either 20 mg/d fluoxetine (FLX) or placebo for 6 weeks [26].
