Immuniz not crd out bec chronic illness or cond of patient

This code indicates that a patient did not receive a recommended immunization due to an existing, long-term health issue. This chronic condition poses a contraindication or significant risk that outweighs the benefits of vaccination at that time. It documents a medical reason for deferring or declining an immunization.

Use this code when a patient presents for an immunization but the healthcare provider determines that a pre-existing chronic illness, such as severe immunosuppression, uncontrolled autoimmune disease, or a specific neurological disorder, prevents the safe administration of the vaccine. This applies when the decision to not immunize is based solely on the patient's chronic medical status.

• Always sequence this code as a secondary diagnosis, following the code for the specific chronic condition that contraindicates the immunization.
• Do not use this code if the immunization was not carried out due to patient refusal, lack of supply, or acute illness; other Z codes exist for those scenarios.
• Ensure documentation clearly states the chronic condition and the medical rationale for not administering the immunization.
