2026 Subsequent Encounter ICD-10-CM Codes ICD-10-CM

The FY 2026 dataset contains 22,194 subsequent encounter codes across 415 code blocks. Subsequent encounter codes carry the 7th character D and are assigned after active treatment has ended, while the patient receives routine care during the recovery or healing phase. They apply when the patient is monitored, evaluated, or managed while healing, regardless of the number of follow-up visits.

Questions About This Page

How many subsequent encounter codes are there in FY 2026?

The FY 2026 dataset contains 22,194 subsequent encounter codes across 415 code blocks, 22,194 of them billable.

Why does this page list blocks instead of every code?

Because every block already has a complete, filterable code page in the tabular index. This list gets you to the right block fast; the block page carries every code with its notations and details.

Which block has the most subsequent encounter codes?

Fracture of lower leg, including ankle (S82) is the largest with 2,316 codes.
