As anyone who has read even a few posts knows, HPV is a very complicated issue!
As an HPV awareness advocate, nothing is more upsetting than to have inaccurate information disseminated, especially to newly diagnosed individuals. This occurs a lot on websites where there are no restrictions on what is posted and these sites are not certified by HONCode (an organization which certifies that the site adheres to standards of ethics and the dissemination of ACCURATE medical information). Unfortunately dissemination of inaccurate information also occurs on forums and blogs.
Several decades ago, it became obvious that the original classification of cervical abnormalities created by George Papanicolaou (the man who developed the Pap smear) was not reproducible and a cause for confusion amongst both pathologists and clinicians.
As a result, a pathologist named Ralph M. Richart developed the currently used nomenclature of CIN (cervical intraepithelial neoplasia) as a means to unify the medical community in not only its understanding of the level of disease but the adequate treatment of it as well.

Dr. Richart, a pathologist at Columbia Presbyterian Medical Center in NYC is credited with the current system of CIN vocabulary and is credited with over 270 articles relating to this subject as well as it's relation to HPV, HIV, screening methods etc.

As an aside, the medical community has several other systems which unify the understanding not only of procedures (CPT codes) but diagnoses (ICD-9 codes). A mistake in coding (particularly with ICD-9 codes) can be very detrimental to a patient ranging from denial of payment, refusal to issue life insurance, denial of insurance claims and many others.
Dr. Richart, in conjunction with Dr. Thomas C. Wright, also from CPMC in NYC, have worked together in this area for decades and are indeed the pioneers of the current intraepithelial neoplasia "IN" system (it is applicable regardless of origin and applies to VIN, VaIN, and AIN as well as CIN).
I am honored in a sense to say, that since my diagnosis with HPV in 1987 until 2002, it has been both Dr. Richart and Dr. Wright who have been responsible for the diagnostic pathology not only of every biopsy I have had, but also for interpretation of every in situ hybridization for HPV DNA which has been run on my biopsies as well.
If anyone can put an end to the debate over whether CIN3 and CIS (carcinoma in situ) are one and the same, it certainly would be Dr. Richart, after all it's HIS system we're talking about here. Obviously there will be those in the medical field who continue to utilize outdated methods of terminology/characterization but this does not mean they are correct. If anything, they should be responsible to bring themselves up-to-date and utilize (and understand!) the current system for the betterment of all patients and the patient's subsequent care.
So, in an effort to end this confusion once and for all and given that he worked on my case for 15 years, I called Dr. Richart today. He confirmed that CIS was a part of the “old” system of grading and really should not be utilized any longer (this is why he developed the “IN” nomenclature). He also stated that functionally, the IN3 diagnosis and CIS diagnosis are one and the same! In fact, there is only one diagnosis code which covers both these terms and that is 233.1.
He went further to agree, that any insurance company which is covering an individual on a cancer policy, and whose language states that they cover a CIS but are rejecting a CIN3 need to have their doctors get this straightened out with the insurance company so they can receive their benefits.
So, hopefully those who have remained confused claiming that an IN3 diagnosis (regardless of site of origin, CIN, VIN etc) was NOT the same as CIS, you can rest assured that the creator of the IN system makes clear that it is!
