Medical Billing Code Books
Code Books are a necessary part of medical insurance billing.
You will find that you are frequently looking up codes and you
need up to date code books to accomplish this. Medical billing
codes change every year and when they
are outdated, the insurance companies will no longer accept them and your
claims will be denied for the codes.
What billing code books are available
and required? CPT4, ICD9, HCPCS, and RBRVS are all available.
CPT Code Books
- or Current Procedural
Terminology. Services and procedures performed by physicians are
described by the use of CPT codes. CPT code books are listings of
all procedure codes with an explanation of each code. They are
listed both by number and alphabetically.
These codes are
updated annually and it is important to be aware of the changes each
year. Sometimes the changes are minimal, but sometimes there are a
lot of changes and it impacts a provider greatly.
CPT Code Books also
contain a list of modifiers. Modifiers indicate that a service was
altered in some way from the stated CPT descriptor without changing the
definition. The American Medical Association (AMA) CPT modifiers are
two-digit numeric codes listed after a
ICD9 Code Books - or The International
Classification of Diseases, 9th Revision, Clinical Modification. The
ICD9 coding system is an international classification system which groups
related disease entities and procedures for the purpose of reporting
statistical information. It is a system of descriptions
and codes used to record the occurrence of medical

diagnoses both alphabetically and numerically. These codes are
also updated annually. Again, the updates are very important.
If you use outdated ICD9 codes your claims will most likely be
HCPCS Code Books - or Healthcare Common
Procedure Coding System. HCPCS is a standardized coding system that
is used primarily to identify products, supplies, and services not
included in the CPT codes, such as ambulance services and durable medical
equipment, prosthetics, orthotics, and supplies (DMEPOS) when used outside
a physician's office.
As with the other billing code books, HCPCS are also updated annually.
Unless you are a provider, or a billing service who bills for a provider,
who supplies patients with services or supplies not covered in the
CPT4 code book, you will not use these codes.
You can also
purchase specialized code books. We've seen them for anesthia
If you are a specialty office, or you are a billing
service who bills for only a small group of specialty providers, you may
want to look into these. They are usually less expensive and contain
data only relative to that specialty.
