Code Classification

    • 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 U09.9 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.

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.

New 2022 ICD-10 Code

U09.9 is new to ICD-10 code set for the FY 2022, effective October 1, 2021. The National Center for Health Statistics (NCHS) has published an update to the ICD-10-CM diagnosis codes which became effective October 1, 2021. This is a new and revised code for the FY 2022 (October 1, 2021 - September 30, 2022).

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.
