In numerous tables in Marketscape, you will find tables that contain Diagnostic Groupings that organize metrics in the table. These groups, in general, contain similar diagnoses that align with an organ system or related medical specialty. Our groupings are based on the ICD-10-CM Chapters which divide all ICD-10 codes into 21 groups with specific code ranges. The table below shows this alignment with some important qualifications.
For more information on the ICD-10 Chapters, click ICD-10-CM Chapters.
We have also provided a spreadsheet that will allow you to look up a specific ICD-10 code and pinpoint which chapter is matched to each ICD-10 code, and consequently to the Trella Health Diagnostic group in the table.
Although many places in Marketscape mention "Diagnostic Categories," or "Major Diagnostic Categories," do not try to draw a connection to CMS's Major Diagnostic Categories (MDC). In some cases you will be able to find an obvious similarity, but the alignment will not work for all groupings or diagnoses.
This sample image shows how the Trella Health Diagnostic Groupings appear in a table. It is possible that some diagnostic groups will not be represented in a table. If there are no claims to populate a diagnostic group, we will not include that group in the table. Also, if the patient count in a group is too small to reveal, that is, the patient count is less than 11 (<11) we will add that group to the category, Aggregated INS MDCs.
Each listing in the central column in the table below is a link to the next level of detail on what the ICD-10 chapter includes.
|EH Diagnostic Grouping found in the Portal||ICD-10-CM Chapter Name||ICD-10 Code Range|
|Aggregated INS MDC's||See comments below||varies|
|Blood & Immunological||D50-D89|
|Ear & Mastoid Process||H60-H95|
|Endocrine & Metobolic||E00-E89|
|Eye & Adnexa||H00-H59|
|Factors Influencing Health||Z00-Z99|
|Injury & Poisoning||S00-T88|
Other Abnormal Findings
|Pregnancy & Childbirth||O00-O9A|
Aggregated INS MDCs
The first entry is titled, “Aggregated INS MDC’s” which represents the combined percentage for all diagnostic groupings that are too small to be presented on their own. In any case where the total number of patients in a specific diagnostic group drops below 11 patients, we can't show that number for privacy reasons. We roll all diagnostic groups that represent counts <11 into this one category and present that total percentage under this header. Another way to look at it: this row includes all diagnostic groups that have insufficient counts aggregated into a single metric. It is possible that this group itself could contain less than 11 (<11).
Other Abnormal Findings
This category includes the following general categories of diagnoses. For more information on ICD-10 codes in this category, see the attached spreadsheet (below)
- Abnormality of Gait
- Chronic Fatigue Syndrome
- Adult Failure to Thrive
- Septic Shock
- Retention of Urine
- Generalized Edema
- Syncope and Collapse
Chapters 18, 19, 21 - Factors Influencing Health
These chapters include a broad collection of diverse diagnoses. We combed through the entire list and reassigned each diagnosis to one of the other groups that seemed more appropriate. There is no simple category or algorithm for describing where we placed the diagnoses from this category. The attached Spreadsheet at the bottom of the page will allow you to look for the placement of any missing ICD-10 code.
Knee and Hip Replacements
If a patient has a knee or hip replacement, the Diagnostic grouping for the subsequent care would be different depending on the initial reason for the care. For example, if a patient falls in their home and causes an injury that requires a knee replacement, the DG would be Injury and Poisoning. In contrast, an elective total knee replacement would be considered Musculoskeletal System and Connective Tissue. In other words, the same post operative treatment could show up in different Diagnostic Groupings.
Locating a Specific Diagnosis
The attached spreadsheet contains the ICD-10 diagnoses codes, their descriptions along with the ICD-10-CM chapters to which each diagnosis aligns. In addition, we have listed the diagnostic groupings names as they are found in Marketscape. By searching for a specific ICD-10 code, you can identify how that diagnosis aligns with the metrics in Marketscape. Instructions are included in the Spreadsheet.
