Coding instructions

Official Tabular Instructional Notes: the inclusion, exclusion and sequencing notes published for S89.29 in the official ICD-10-CM tabular list, quoted as published.

Notes without a marker are published on S89.29 itself; “inherited from” names the category or block whose note applies here.

Excludes2 — Not Included Here

Conditions not covered by this code, but which may be reported alongside it when both are present.

7th Character Guide

"The appropriate 7th character is to be added to each code from subcategories S89.0, S89.1, S89.2, and S89.3"

  • A — initial encounter for closed fracture
  • D — subsequent encounter for fracture with routine healing
  • G — subsequent encounter for fracture with delayed healing
  • K — subsequent encounter for fracture with nonunion
  • P — subsequent encounter for fracture with malunion
  • S — sequela

How the encounter character is assigned. “Initial encounter” means the patient is receiving active treatment for the condition — it is not limited to the first visit, and a different or new provider giving active treatment still assigns it. “Subsequent encounter” covers care during the healing or recovery phase after active treatment. “Sequela” is for complications or conditions that arise as a direct result of the original condition.
