* ICD-9-CM = International Classification of Diseases, Ninth Revision, Clinical Modification; SPARC = significant pediatric arthritis and other rheumatologic conditions.

† Visit data include the following emergency department visits that were not used to estimate prevalence: 719.4 = 139,000; 729.5 = 108,000; 729.8 = 40,000; 719.0 = 23,000; 728.8 = 15,000; the first two estimates were based on more than 30 records; the latter two were not and should be considered unreliable. The remaining codes with ED visits all had estimates less than 15,000.

‡ Conditions that are not a subset of NADW adult definition.

§ Estimate for 719.4 based on >30 records and has relative standard error less than 30%.; estimates for 726, 729.5, 727.4, 719.0, 728.8, 729.8 and 719.9 are based on >30 records but have relative standard errors greater than 30%. All other estimates are based on less than 30 records.

Note: The following ICD-9-CM codes all contributed less than 3% to either prevalence or visit estimates: 3.23‡, 36.82‡, 56.71‡, 95.6, 95.7, 98.5, 135‡, 272.8‡, 277.2, 279.8‡, 344.6, 353.0, 354.0, 355.5, 357.1, 364.1‡, 443.89‡, 719.1, 719.5, 721, 727.1, 727.2, 727.3, 727.5, 727.9, 728.0, 728.1, 728.2, 728.3, 728.4, 728.5, 728.6, 728.7, 729.3‡ and 733.4‡.
