2026 Initial Encounter ICD-10-CM Codes ICD-10-CM
Home › ICD-10-CM Codes List › Tags › Initial EncounterThe FY 2026 dataset contains 14,576 initial encounter codes across 415 code blocks. Initial encounter codes carry the 7th character A and are reported while a patient receives active treatment for an injury, poisoning, or other external cause condition. An initial encounter does not always mean the first visit; it refers to the active treatment phase, which may include multiple visits.
✓ Built from the official CMS FY 2026 dataset Effective Oct 1, 2025 – Sep 30, 2026
An initial encounter covers the whole active treatment phase: the emergency visit, surgery, and evaluation by a new physician can all be initial encounters. Once care moves to routine healing, the subsequent encounter codes apply instead.

Questions About This Page How many initial encounter codes are there in FY 2026? The FY 2026 dataset contains 14,576 initial encounter codes across 415 code blocks, 14,576 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 initial encounter codes? Fracture of lower leg, including ankle (S82) is the largest with 579 codes.
