ICD – 10 Guidelines Chapter-1 Selection and Sequencing of MRSA

Methicillin Resistant Staphylococcus aureus Conditions

1) Selection and sequencing of

(a) Combination for infection

When a patient is diagnosed with infection like sepsis due to MRSA give combination

Sepsis due to Methicillin resistant aureus code A41.02

Pneumonia due to Methicillin resistant Staphylococcus aureus c J15.212

B95.62, Methicillin resistant aureus infection as the cause of diseases classified elsewhere, as an additional code,

Because the combination code includes the type of infection and the MRSA organism

Don’t code z 16.11 resistance to pencillins

(b) Other for infection

When a patient is diagnosed with infection like (e.g., wound infection, stitch abscess, urinary tract infection) due to MRSA and this if we don’t have combo code

so in this cases B95.62, Methicillin resistant Staphylococcus aureus infection as the cause of diseases classified elsewhere for the MRSA infection.

Don’t code z 16.11 resistance to pencillins

UTI due to MRSA how to code?

PDX:n39.0

SDX:B95.62

(c) Methicillin susceptible aureus () and colonization

Colonization or carrying: when MSSA or organism is present in the body without causing illness is known as colonization or carrier of MSSA.

When the positive colonization documentation is given by provider such as” screen positive” or “nasal swab positive”.

code Z22.322, Carrier or suspected carrier of Methicillin resistant Staphylococcus aureus, for patients documented as having MRSA colonization.

code Z22.321, Carrier or suspected carrier of Methicillin susceptible aureus, for patient documented as having MSSA colonization.

(d) MRSA colonization and infection

When patient is having both MRSA colonization and infection developed during admission both infection and MRSA colonization.

Ex: sepsis and MRSA colonization.

PDX: A41.9

SDX: Z22.322

(f) Zika virus infections.

1) only confirmed cases

When provider documentation is given as conformed zika virus then A92.5.

Don’t code if documentation is given as probable, suspected or possible assign the reason for visit complaint like fever, joint pain etc., or

Z20.828, Contact with and (suspected) exposure to other viral communicable diseases.

4) Sepsis and severe sepsis with a localized infection

If patient admitted with sepsis and severe sepsis and a local infection such as pneumonia and cellulitis

First code systemic infection is coded

Second localized infection is coded

Third severe sepsis is coded.

If patient admitted for local infection and there is no severe sepsis until admission and developed later then

First local infection is coded

Second sepsis, severe sepsis.
