K58.2 Diagnosis Code
Christain Cobb
Other symptoms in the intestines may for instance be abdominal cramps, flatulence and a pulling or twinge in the abdomen. You were examined due to your bowel complaint. No changes that are typical for other diseases of the intestines were found in the course of this. In your case, what is known as irritable bowel syndrome was detected.
With irritable bowel syndrome, the intestines react differently than usual. The intestines are constantly expanding and contracting in order to convey intestinal contents. This is not usually noticeable. With irritable bowel syndrome on the other hand, you may have symptoms when the intestines expand. It is also possible for the intestinal contents to be conveyed slower than usual. The symptoms may lessen after the bowel movement. You may also have the feelings of not being able to excrete everything during your bowel movement.
Various influences can cause irritable bowel syndrome or make it worse. Sometimes, irritable bowel syndrome develops after a stomach bug. Psychological influences such as constant stress may also encourage bowel complaints.

This Billing and Coding Article provides billing and coding guidance for Local Coverage Determination (LCD) L33671 (Diagnostic Colonoscopy). Please refer to the LCD for reasonable and necessary requirements.
Notice: It is not appropriate to bill Medicare for services that are not covered (as described by the entire LCD) as if they are covered. When billing for non-covered services, use the appropriate modifier.
Explanation of Revision: Based on CR 11895 and CR 11845 (Annual 2021 ICD-10-CM Update) the billing and coding article was revised. ICD-10 Code K59.8 was removed and ICD-10 codes K59.81 and K59.89 were added to the "ICD-10 Codes that Support Medical Necessity/Group 1 Codes:" section of this billing and coding article. Additional formatting changes have been made throughout the document. The effective date of this revision is based on date of service.
An asterisk (*) indicates arequired field. This email will be sent from you to therecipient email address(es) you enter. Please do not use this feature to contact CMS.To submit a comment or question to CMS, please use the Feedback/Ask a Question link available at the bottomof every MCD page.
Articles are a type of document published by the Medicare Administrative Contractors (MACs). Articles often contain coding or other guidelines and may or may not be in support of a Local Coverage Determination (LCD).
For the most part, codes are no longer included in the LCD (policy). You will find them in the Billing & Coding Articles. Try using the MCD Search to find what you're looking for. Enter the code you're looking for in the "Enter keyword, code, or document ID" box. The list of results will include documents which contain the code you entered.
Please Note: For Durable Medical Equipment (DME) MACs only, CPT/HCPCS codes remain located in LCDs. All other Codes (ICD-10, Bill Type, and Revenue) have moved to Articles for DME MACs, as they have for the other Local Coverage MAC types.
NCDs do not contain claims processing information like diagnosis or procedure codes nor do they give instructions to the provider on how to bill Medicare for the service or item. For this supplementary claims processing information we rely on other CMS publications, namely Change Requests (CR) Transmittals and inclusions in the Medicare Fee-For-Service Claims Processing Manual (CPM).
In order for CMS to change billing and claims processing systems to accommodate the coverage conditions within the NCD, we instruct contractors and system maintainers to modify the claims processing systems at the national or local level through CR Transmittals. CRs are not policy, rather CRs are used to relay instructions regarding the edits of the various claims processing systems in very descriptive, technical language usually employing the codes or code combinations likely to be encountered with claims subject to the policy in question. As clinical or administrative codes change or system or policy requirements dictate, CR instructions are updated to ensure the systems are applying the most appropriate claims processing instructions applicable to the policy.
Enter the CPT/HCPCS code in the MCD Search and select your state from the drop down. (You may have to accept the AMA License Agreement.) Look for a Billing and Coding Article in the results and open it. (Or, for DME MACs only, look for an LCD.) Review the article, in particular the Coding Information section.
If you need more information on coverage, contact the Medicare Administrative Contractor (MAC) who published the document. The contractor information can be found at the top of the document in the Contractor Information section (expand the section to see the details).
2) Try using the MCD Search and enter your information in the "Enter keyword, code, or document ID" box. Your information could include a keyword or topic you're interested in; a Local Coverage Determination (LCD) policy or Article ID; or a CPT/HCPCS procedure/billing code or an ICD-10-CM diagnosis code. Try entering any of this type of information provided in your denial letter.
The ICD-10 classification is an international standard for the codingof health service data. It is used widely both to document morbidity inhealthcare systems, usually in the context of remuneration claims, andto encode mortalitystatistics. In Germany, the GermanInstutite of Medical Documentation and Information (DIMDI) releasesa German Modification (ICD-10-GM) of the classification that forms acompulsory part of all remuneration claims in the ambulatory andhospital sectors. Further information and historical context can befound in, for example, Graubner (2007) orJett et al(2010).
ICD10gm is designed for use in the context of medical and healthservices research using routinely collected claims data. It is notsuitable for use in operative coding as it does not include all relevantmetadata (e.g. inclusion and exclusion notes and the detaileddefinitions of psychiatric diagnoses). The metadata provided in theICD10gm package is not intended to replace the officialDIMDI documentation, which should always be consulted whenspecifying ICD codes for analysis.
By way of example, we examine the coding of unspecificgastroenteritis (i.e. without identification of a specific cause), avery common diagnosis in primary care. We can look up the appropriatecode as follows:
We see that A09 is used for infectious gastroenteritis, whereas K52corresponds to non-infectious gastroenteritis. We are interested in A09,but might wish to read up on the details in the officialdocumentation:
Prior to 2010, A09 had been reserved for gastroenteritis of presumedinfectious origin (German: vermutlich infektisen Ursprungs),with unspecified gastroenteritis coded by K52.9. Since 2010, A09.9 codesany unspecified gastroenteritis, with K52.9 reserved for casesdetermined to be non-infectious. The effect of this change is that A09.9has replaced K52.9 as the unspecific code used to document the vastmajority of routine cases in primary care. Failure to account for thiswould constitute a major error in medical or epidemiologicalresearch.
The function is_icd_code tests whether a charactervector represents a valid ICD-10-GM code (i.e. a code listed in thedata.frame icd_meta_codes, allowing for alternative codespecifications). The test may be limited to a particular version of theICD-10-GM by specifying the year argument.
The function icd_parse extracts all ICD-10 codes from anarbitrary character vector. On the one hand, this may be used as in theicd_expand function to convert ICD-10 codes to astandardised format or extract parts of the code. On the other hand, itmay be used to extract potentially many ICD-10 codes from any documentthat can be converted to text format (perhaps using the pdftoolspackage to scrape a PDF document or rvestto scrape a website).
Irritable bowel syndrome is coded using either the three-digit codeK58 (conceiving IBS as the somatic condition) or the code F45.32(focussing on IBS as a psychosomatic condition). We can retrieve allsubcodes in the year 2019 as follows:
The function icd_history takes the result oficd_expand, specified for a particular year, and returns adata.frame containing all corresponding codes for the specified years(from 2003). To do this, it applies the ICD-10-GM transition tables tomap codes between successive ICD-10-GM versions. Only automatictransitions are followed to ensure that the specification retains itsmeaning. Custom transitions, tailored to the needs of the project athand, can be specified to yield a more complete history.
The underlying ICD-10-GM metadata is copyright of the German Instutite of Medical Documentationand Information (DIMDI). The source files are available free ofcharge from the DIMDIDownload Centre. I believe that their use in this package iscompatible with the copyright restrictions. In particular:
Distribution of the original classification files is forbidden.Consequently, this package distributes only the code required to processthese files. Those wishing to compile the data from scratch mustdownload the files from the DIMDI download centre and agree to thecopyright restrictions.
