has a complete listing of all current medical diagnosis

deadly diseases and are used to specify certain diseases or
This code book is
updated yearly to allow for changes in the diagnosis. New 2008 code books are just being released now in September. Make
sure you use current codes as the insurance claims will be denied if you use an outdated code. You will
then have to resubmit the claim with an adjustment form.
Codes in the
book are listed numerically in one section and alphabetically by condition
in another. This makes it easier to look up diseases. They are also grouped together numerically by disease
and malady. Codes are three, four, or five digits. You must code insurance claims to the
highest level of specificity meaning if there is a fourth or fifth digit, you must use them.
ICD9 stands for
The International Classification of Diseases, 9th Revision, Clinical
Modification. This is an international classification system which
groups related diseases and conditions for uniformity in the medical field
for insurance billing.
