    Hi,
    The use of ‘view’ versus ‘views’ is intended to imply singular versus plural. In your example of AP (anteroposterior) view, this is a singular view, but specific to how the view was obtained, whereas the view 1 example means that it doesn’t matter how the view was obtained.
    The use of ‘view’ for the LOINC codes used to report fluoroscopic time regardless of the body system or the plane in which the fluoroscopic view was obtained.
    There is a Radiology tutorial on the LOINC website as well as the LOINC User’s Guide that will be of help in understanding the nomenclature. Also, please post any other questions or comments here on the forum. We are happy to help.

    Regards,

    The Rad class of LOINC do have some terms for ‘2 or more views’, but not for all studies. This is expressed in LOINC as ‘Views GE2’ in the component of the LOINC term. GE means ‘greater than or equal to.’ You will also see ‘Views LE 3’ which means ‘lesser than or equal to.’ This nomenclature comes from CPT as a means of limiting reimbursement for studies regardless of the number of views. Due to the ambiquity of the terms, these are usually discouraged from being used because; 1) an ordering physician usually does not indicate the number of views for the study, and 2) the Radiologist will specify the exact number of and type of views obtained. However, radiology is often mapped off the hospital chargemaster, which is directly related to billing.
    Hope this helps. Please feel free to request additional LOINC terms if there is something that is needed and you cannot find it.
    Best Regards,
    Pat

    Eric,
    Glad that you were able to find the explanation of the acronyms within the User’s Guide. The Radiology terms can be a bet cryptic. Some of the terms have perpetuated the naming conventions of other standards. Such is the case with the ‘GE’ and “LE’, which were derived from CPT nomenclature.
    A specific presentation is given each Clinical LOINC meeting discussing radiology within LOINC. The slides for these presentations are on the LOINC.org website. It might be helpful to review those slides for a bit of background regarding radiology within LOINC.
    Happy ‘LOINCing!’ (yes, it is a verb!)

    Using CPT codes is not the best method for matching your terms to LOINC, but I can certainly understand why you would think so. The NLM actually has a Rad CPT to LOINC map that was done a while ago but have not published it due to lack of interest. I will let the NLM know of the interest to see if we can post a link here on this forum.
    Some general rules to follow in the meantime are:
    1) Most of the LOINC terms have been built taking into consideration the Radiology section of the CPT (the 70000 series), with the main objective being the Radiology component of the CPT code. Therefore, you may not find LOINC codes, at this time, for the injection of contrast, or the ‘surgical’ component of interventional radiology terms.
    2) CPT does not take into consideration laterality, except with the use of modifiers. LOINC is explicit with this.
    3) CPT is also general in body location, such as Right Upper Quadrant. LOINC is more specific
    4) CPT does not always combine body sites, some LOINC terms do. This has been a debated issue, especially where it applies to CT.

    If you have any specific issues to discuss, this is a great place to post your question. If each of you are having an issue, chances are, others may be having the same problem.
    Also, there are some areas of Radiology that still need to be addressed. Again, your comments and feedback are helpful in providing updates to LOINC.

    No, we do not have a LOINC code for CT Virtual Colonoscopy at this time. We will get a term created as soon as possible.

    Currently there is no LOINC term with a system of Chest+Abdomen+Pelvis. My suggestion would be to use the LOINC term with Abdomen+Pelvis, and another LOINC term for Chest alone.
    We can also discuss this at the next Clinical LOINC meeting to determine if this type of combination should be considered.
