Introduce Teclistamab in Subcu, Perc, New Tech 8

This code describes the administration of Teclistamab, a bispecific antibody used in cancer treatment, directly into the subcutaneous tissue. This is a targeted therapy delivered via injection through the skin, bypassing the need for intravenous access.

This code is used when a patient receives Teclistamab for the treatment of relapsed or refractory multiple myeloma. It specifically applies to the percutaneous (injection through the skin) route of administration. This code should be assigned for each instance of Teclistamab administration via this method.

• Ensure documentation clearly specifies "Teclistamab" as the substance introduced.
• Verify the route of administration is explicitly documented as "subcutaneous" and "percutaneous."
• This code is for the introduction of the substance; separate codes may be needed for any associated procedures (e.g., port insertion, if applicable, though less common for subcutaneous).
