Acquired Diagnosis / Complication
- Acquired Diagnoses, also referred to as complications, are problems or procedures that occur AFTER a patient has been accepted to a physician service ICU or Medicine regardless of physical location and has an Service tmp entry dttm. (While in ER collection starts at Accept DtTm).
- Acquired diagnoses are prioritized (Dx Priority field) in order of occurrence.
- Coding for Acquireds/complications follows the general ICD10 collection instructions.
- The Dx_Date is mandatory for Acquireds/complications.
Como Admit Acquired Primary Limits - this is part of that discussion - if we limit which admits will count as comos we need to review
When to code an Admit Diagnosis vs Acquired Diagnosis
- Distinction between Admit Diagnoses and Acquired Diagnoses relate to the start of a PatientFollow Project profile. An Admit Diagnosis needs to be present at the start of a PatientFollow Project profile. Diagnoses that occur after will be Acquired Diagnosis.
Onset not discovery
Acquired diagnoses do not refer to diagnoses that have been discovered after the patient comes to the unit if it is likely that the patient was admitted to ward with the problem in the first place but it took a few days to figure that out. Code these as Comorbid Diagnosis, and also, if appropriate (i.e. it was related to the reason for admission) as a Admit Diagnosis.
Diagnosis categories in relation to patients moving around the hospital
- This section explains how to determine the Dx Types as a patient moves from place to place within a hospital -- i.e. during a single hospitalization. In this section we'll refer to a person who moves from A to B to C (e.g. A and C are ICU while B is ward; so 3 separate records in the database)
- Rule#1: Situation where a diagnosis is NEW to this hospitalization [i.e. either it: (a) was an Admit Diagnosis to location A that was not a chronic, pre-existing disorder before hospitalization, OR (b) developed after admission, as an acquired diagnosis while in location A], then:
- when you start records B or C do NOT include that diagnosis as a comorbid
- if by the time they are transferred to the subsequent location it is resolved and no longer being treated, then it should not show up as any kind of diagnosis for that subsequent record
- if by the time they are transferred to the subsequent location it is still being dealt with medically, and indeed is part of the reasons they are going to the new location, then it should be listed as an Admit Diagnosis for that subsequent record
- Rule#2: The group of diagnoses that represent "past history" (e.g. Past history, loss of limb(s) are also guided by Rule#1.
- Rule#3: The "duration" of a diagnostic event (e.g. pneumonia vs. an arrythmia) has no role in decision-making about how these diagnoses are listed (or not)
Legacy - prior to PatientFollow Project
|expand for pre-PatientFollow Project info|
Prior to PatientFollow Project there was one record per ward/unit stay, so the distinction between Admit Diagnosis and Acquired Diagnosis would have been made on a per-unit basis; since then it is made on a per-PatientFollow Project profile basis.
This wiki page talks about which ICD10 codes are allowed to be Comorbid Diagnosis vs. Admit Diagnosis vs. Acquired Diagnosis Dx Type. See Controlling Dx Type for ICD10 codes for a discussion about cross-checks for these.
this relates to Attribution of infections and we need to be sure to have it consistent.
- In general things that occur, fully resolve, and then recur SHOULD be coded each time they recur.
- e.g. postop hemorrhage --> goes to OR to have it fixed --> IS fixed ---> 3 days later has more postop hemorrhage
- For things that happen multiple times, some we WANT to list multiply and others we only list once
- The ones we only list once include that info: Template:ICD10 Guideline repeated events. These are generally signs/symptoms, and arrythmias.
- Otherwise, DO list it multiply --- e.g. after admit has a stroke --> 4 days later has a NEW/DIFFERENT stroke.
