2025 Subsequent ICD-10-CM Codes - Page 45

The 2025 Subsequent ICD-10-CM Codes list includes 22,121 codes assigned after a patient has completed active treatment and is receiving routine care during the recovery or healing phase. Subsequent encounter codes apply when the patient is monitored, evaluated, or managed while healing, regardless of the number of follow-up visits required. Coders should ensure documentation reflects continued care rather than active treatment. Using the correct subsequent encounter code supports proper claims submission and helps prevent billing errors or denials.
