A five-year-old child was admitted for chemotherapy. It was discovered that he had a clotted peripherally inserted central catheter (PICC) line. He required central access to complete his chemotherapy for acute lymphocytic leukemia (ALL). The line was declotted using Alteplase, which was instilled into the catheter. This dissolved the blockage and the line could be used again. How should this case be coded?
Assign code V58.11, Encounter for antineoplastic chemotherapy, as the principal diagnosis. Assign codes 204.00, Lymphoid leukemia, Acute, Without mention of remission, for the ALL and 996.1, Mechanical complication of other vascular device, implant, and graft, for the clotted PICC line as additional diagnoses. Assign code 99.25, Injection or infusion of cancer chemotherapeutic substance, and code 99.10, Injection or infusion of thrombolytic agent, for the procedures.
