  • This is a "wastebasket" code for clinical observation that does not fit under any of the other observation codes (see below).
  • Observation refers to being watched for having a clinical condition, BUT it turned out after all that that condition was NOT present.
  • use this code for drug desensitization and combine with Allergic reaction (allergy), NOS There is no need for a corresponding CCI code as per TASK meeting June 22, 2022. If the patient has a reaction you can combine this code with the type of drug and adverse effect, as an acquired diagnosis.
