New ICD codes for the covid-19 pandemic

Two new diagnostic codes valid until 2020-10-16 after a decision from the WHO and the National Board of Health and Welfare.

U09.9 - Postinfectious state after covid-19

Additional code that can be used to describe a permit's relationship with covid-19. The code should not be used in the case of covid-19.
Cannot be a main ICU diagnosis.

Encoding examples:
Patient who five months ago fell ill with covid-19. Now have residual symptoms in the form of anosmia (lack of sense of smell).
R43.0 Anosmia + U09.9 Postinfektious state after covid-19

U10.9 - Multisystemic inflammatory
syndrome associated with covid-19


Condition temporally associated with covid-19:

  • Cytokinstorm
  • Kawasaki-like syndrome
  • Multisystem Inflammatory Syndrome in Children [MIS-C]
  • Paediatric Inflammatory Multisystem Syndrome [PIMS]
Mucocutaneous lymph node syndrome [Kawasaki] (M30.3)

Encoding example (current interpretation that is subject to change)
Temporally in connection with Covid infection. U07.1 Covid-19, virus demonstrated + U10.9 Multisystemic inflammatory syndrome associated with covid-19.

If the covid-19 infection is not considered, but there is continued inflammatory syndrome, U10.9 can be used as a standalone diagnosis and then also be selected as the main ICU diagnosis if relevant.

U07.1 and U07.2 aggregated to SIR code JA36
Z86.1A, U09.9, and U10.9 aggregated to SIR code JA37
