Code Classification

  • Codes for Special Purposes
    (U00–U85)
    • Provisional assignment of new diseases of uncertain etiology or emergency use
      (U00-U49)
      • Post COVID-19 condition
        (U09)

U09.9 is a billable diagnosis code used to specify a medical diagnosis of post covid-19 condition, unspecified. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Unspecified diagnosis codes like U09.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Chronic post-COVID-19 syndrome
  • Post-acute COVID-19

Tabular List of Diseases and Injuries

Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Post-acute sequela of COVID-19

Code First

Code First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
  • the specific condition related to COVID-19 if known, such as:
  • chronic respiratory failure J96.1
  • loss of smell R43.8
  • loss of taste R43.8
  • multisystem inflammatory syndrome M35.81
  • pulmonary embolism I26
  • pulmonary fibrosis J84.10

  • This code enables establishment of a link with COVID-19.
  • This code is not to be used in cases that are still presenting with active COVID-19. However, an exception is made in cases of re-infection with COVID-19, occurring with a condition related to prior COVID-19.

COVID-19 (Coronavirus Disease 2019)

COVID-19 (coronavirus disease 2019) is an illness caused by a virus. This virus is a coronavirus called SARS-CoV-2. It spreads when a person who has the infection breathes out droplets and very small particles that contain the virus.
