Answer: For chills that occur due to administration of chemotherapy, you report ICD-10-CM code R68.83 (Chills [without fever]). Additionally, you also need to submit a code to imply that the chills were an adverse event during chemotherapy. The patient develops these chills during the infusion, so you submit code T45.1X5A (Adverse effect of antineoplastic and immunosuppressive drugs, initial encounter). You should submit code T45.1X5S (Adverse effect of antineoplastic and immunosuppressive drugs, sequel) for any adverse events that follow the administration of chemotherapy.
