What This Code Means
J00 is the ICD-10-CM diagnosis code for acute nasopharyngitis [common cold]. The common cold, which is a viral infection of the nose and throat causing congestion, runny nose, and sore throat. J00 sits in the ICD-10-CM chapter for diseases of the respiratory system (j00-j99), within the section covering acute upper respiratory infections (j00-j06).
J00 is a billable ICD-10-CM code, but no current CMS-HCC V28 community payment mapping is shown, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.
