Retroperitoneal area, diagnostic imaging, abnormal
|Dx:||Retroperitoneal area, diagnostic imaging, abnormal|
|Pre-ICD10 counterpart:||Retroperitoneal Bleed|
|APACHE Como Component:||none|
|APACHE Acute Component:||none|
|External ICD10 Documentation|
This diagnosis is a part of ICD10 collection.
- While the retroperitoneum contains some organs and other specific anatomic structures (kidneys, adrenal glands, ureters, aorta, IVC, part of the duodenum, rectum) some of these have their own specific "abnormal imaging codes", i.e.
- for kidneys and ureters use: Urinary organs/tract, diagnostic imaging, abnormal
- for duodenum and rectum use: GI tract, NOS, diagnostic imaging, abnormal
- And of course, the guidelines are only to use any of these abnormal imaging codes when you don't have a diagnosis for the thing/organ with abnormal imaging.
- So you'd use this code in that situation if none of the other "diagnostic imaging, abnormal" codes are appropriate.
- One very important use of this code is as below, for retroperitoneal hemorrhage.
- This code identifies an abnormal test result, not a disorder.
- The preference is to code the cause of the abnormal test, if known.
- also coding this abnormal test, along with the cause is optional however, it is not necessary.
- When the DX is not known, code likely related other tests and signs and symptoms as Combined ICD10 codes; some likely ones might be listed in #Candidate Combined ICD10 codes.
Retropertitoneal Hemorrhage - special coding instruction
There is no individual diagnosis code for retroperitoneal hemorrhage (retroperitoneal bleed). Use combined ICD10 codes:
Symptom/Sign/Test Result not needed when cause known
- This code identifies a symptom or a sign, or an abnormal test result, not a disorder.
- So, you should code the cause of the symptom/sign/abnormal test, if known -- and if you do so, then also coding and combining the symptom/sign/abnormal test result to that cause is generally optional, but is guided by the following guidelines.
- Here are guidelines for whether or not to ALSO code the symptom/sign/abnormal test when you DO code the underlying cause:
- If it is a subjective symptom (e.g. pain) then coding it is optional
- When it is a physical exam finding (e.g. abdominal tenderness) then coding it is generally optional
- An exception is when the symptom/sign/abnormal testis so severe that all by itself it mandates hospitalization and/or a procedure -- a good example is a patient who has Wegener's granulomatosis is admitted due with Hemoptysis. Since hemoptysis is a physical finding that fits this description of "severe" it should be coded, and combined with Wegener's.
- When it is an abnormal laboratory finding which in and of itself has relevance (e.g. hyperkalemia, hypoalbuminemia) then USUALLY code it
- You don't need to code the abnormal lab finding is when it is actually a major component of the underlying cause --- example is when a person presents with an acute MI, there is no need to code the abnormal troponin as Abnormal blood chemistry NOS
- The trickiest of these guidelines is for abnormal radiologic tests
- When the abnormal test is fully explained by the underlying diagnosis/diagnoses (e.g. pneumonia as cause of abnormal chest imaging, or a skull fracture with an intracranial hemorrhage both identified by an abnormal head CT) then coding the abnormal imaging result is optional
- But remember there are some rare things for which the abnormal imaging result IS part of coding the entity, for example we code retroperitoneal hemorrhage by the combination of Hemorrhage, NOS and Retroperitoneal area, diagnostic imaging, abnormal
- Sometimes there may be multiple symptom/sign/test result that might or might NOT be related to each other by virtue of having the same underlying cause. Since in the absence of KNOWING that cause, such assumptions may well be incorrect, do NOT combine them together if you are not certain they actually have the same underlying cause.
If this happens repeatedly during the same ward or unit stay, only code it the first time it happens, rather than each time it happens. See ICD10 codes only coded the first time for other diagnoses coded this way.

Guideline about Coding CCI vs ICD10 imaging codes
- There are a set of "imaging codes" in ICD10, but these are not to code that an imaging test was performed, but to code that a result was abnormal --- and like all the ICD10 codes for abnormal symptoms or signs or test results, they are mainly to be used when the actual diagnosis CAUSING the abnormal findings is not known.
ICD10 Imaging diagnoses and other diagnoses that require imaging should be coded together with corresponding Imaging Pxs, where we have a code for them. Coding both is not redundant because the ICD10 will only be coded for abnormal results, and we don't have CCI coding options for every kind of imaging. Coding both as appropriate will cover all the ways we are interested in this data.
