ICD-10-PCS Coding Practice Exam 2025 – Complete Test Prep

The statement is true because in the ICD-10-PCS coding system, the second character in both the Extracorporeal or Systemic Assistance and Performance section and the Extracorporeal or Systemic Therapies section is assigned a value of 'A.' This value indicates the category that encompasses devices, systems, or therapeutic interventions that provide assistance or systemic therapy, emphasizing their reliance on specific concepts related to perfusion or external support.

When coding for procedures under these sections, the consistency of using 'A' as the second character aids coders in recognizing that these procedures fall within the same classification, allowing for easier understanding and usage of the codes in clinical documentation and billing processes.

Other values are utilized in different sections of the ICD-10-PCS code structure, but for these specific areas, 'A' serves as the only input at the second character level, reinforcing the standardization within these code categories.
