Chapter XXII Codes for Special Purposes (and COVID-19 Guidance) Flashcards
How must the statement of MRSA be coded?
U82.1 Resistance to methicillin must be assigned immediately after the code which identifies that the infective agent is staphylococcus aureus
DCS XXII.2
Code U85.X identifies a specific type of resistance. How is it used?
Category U85.X must only be used to identify resistance, non-responsiveness and refractive properties of a neoplasm or other condition to antineoplastic drugs
DCS XXII.2
How must non-infectious conditions classified outside of Chapter XVIII Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified, that are documented as being due to or caused by COVID-19 be coded?
Codes for any condition (including non-infectious conditions) classified outside of Chapter XVIII Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified, that are documented as being due to or caused by COVID-19, must be assigned after U07.1. Each code must be followed by B97.2 excluding codes from Chapter I
COVID-19 NCCS 11.21
When must the code U07.3 Emergency use of U07.3 [Personal history of COVID-19] NOT be assigned?
U07.3 must not be assigned on episodes where patients are being treated for an acute COVID-19 infection (U07.1 Emergency use of U07.1 [COVID-19, virus identified] or U07.2 Emergency use of U07.2 [COVID-19, virus not identified]) or a post COVID-19 condition (U07.4 Emergency use of U07.4 [Post COVID-19 condition])
If more than 1 condition is identified as post-COVID-19 condition, where must the code U07.4 be assigned
- after all conditions listed
- after each condition listed
- before all conditions listed
Where multiple conditions or symptoms are described as post COVID-19, U07.4 must be assigned directly after each of the codes that classify the conditions or symptoms.
Whenever coronavirus is documented in the medical record as a laboratory identified virus causing a disease classified to a body system chapter, both codes U07.1 and B97.2 must be used in the coding summary. Is this statement true or false?
False. Emergency code U07.1 must only be used when COVID-19 virus has been identified.
(NB: coronavirus has first been identified as a causative agent for respiratory disorders in 1930-s)
In cases of multi-drug resistance, when is it permissible not to use individual four-character codes within categories U82.-, U83.- or U84.- and use codes U83.7 Resistance to multiple antibiotics or U84.7 Resistance to multiple antimicrobial drugs instead? (2 cases)
- An agent is resistant to two or more antibiotic/antimicrobial drugs each classifiable to U83.8 Resistance to other single specified antibiotic or U84.8 Resistance to other specified antimicrobial drug.
- An agent is resistant to two or more antibiotic/antimicrobial drugs where the antibiotic/antimicrobial drugs are not specified.
DCS XXII.2
What are the 3 condition for the use of categories U82-U85? (Hint: 2 of the conditions are related to sequencing)
- Never be used as primary diagnosis codes
- Only be used in a secondary position, sequenced directly following the code they enhance
- Only be assigned when drug resistance is clearly documented in the medical record by the responsible consultant.
DCS XXII.2
Which documentation must be used when extracting information about resistance?
Resistance codes must be used when this information is clearly documented within the patient’s medical record. The coder must never interpret laboratory results in order to identify the antibiotic/antimicrobial drug to which an agent is resistant
DCS XXII.2
Can the code B97.2 be assigned with codes from codes from Chapter XV Pregnancy, childbirth and the puerperium to identify that a symptom of COVID-19 is complicating labour or delivery, considering it is not a body system chapter?
B97.2 may be assigned with codes from Chapter XV Pregnancy, childbirth and the puerperium to identify that a symptom of COVID-19 is complicating labour or delivery
If confirmed or probable COVID-19 infection is not the main condition treated, what are the rules of sequencing codes U07.1 and U07.2?
The main condition treated or investigated is unrelated to COVID-19 must be sequenced first (DGCS.1: Primary diagnosis must be applied). Where U07.1 or U07.2 does not appear in the primary diagnosis field, it must be sequenced directly after the code for the primary diagnosis, except where another standard prevents this.
If COVID-19 infection was initially suspected, but subsequently ruled out by a negative result, how should this scenario be coded?
- Code for the relevant stated conditions or symptoms
- Z03.8 Observation for other suspected diseases and conditions
Where must the code U07.5 Emergency use of U07.5 [Multisystem inflammatory syndrome associated with COVID-19] be assigned in relation to U07.1 and U07.2, if a patient is concurrently diagnosed with an acute COVID-19 infection?
Where a patient is also documented as having an acute COVID-19 infection (confirmed or suspected), U07.5 must be assigned directly after U07.1 or U07.2.
Are the codes B34.2 Coronavirus infection, unspecified site and U07.1 Emergency use of U07.1 [COVID-19, virus identified] interchangeable?
No, B34.2 Coronavirus infection, unspecified site must not be assigned to classify COVID-19.
COVID-19 NCCS 11/21
What are the acceptable formulations of a suspected COVID-19 infection, which enable the U07.2 code assignment?
U07.2 includes cases of suspected, probable, and presumed COVID-19, or patients being treated as having COVID-19 in the absence of a positive laboratory test where COVID-19 has not been ruled out.
