7th Character Guide

"The appropriate 7th character is to be added to all codes from category S72"

  • A — initial encounter for closed fracture
  • B — initial encounter for open fracture type I or II
  • C — initial encounter for open fracture type IIIA, IIIB, or IIIC
  • D — subsequent encounter for closed fracture with routine healing
  • E — subsequent encounter for open fracture type I or II with routine healing
  • F — subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing
  • G — subsequent encounter for closed fracture with delayed healing
  • H — subsequent encounter for open fracture type I or II with delayed healing
  • J — subsequent encounter for open fracture type IIIA, IIIB, or IIIC with delayed healing
  • K — subsequent encounter for closed fracture with nonunion
  • M — subsequent encounter for open fracture type I or II with nonunion
  • N — subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion
  • P — subsequent encounter for closed fracture with malunion
  • Q — subsequent encounter for open fracture type I or II with malunion
  • R — subsequent encounter for open fracture type IIIA, IIIB, or IIIC 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.

Decision Points

The directives on this code's own record, as a pre-claim checklist.

  1. A 7th character applies in this family. Confirm the documented encounter matches the character assigned. See the official 7th-character definitions and this code’s variants
  2. 1 Excludes1 entry — codes named there are generally not reported together with this code (Guidelines I.A.12.a). See the Excludes1 notes
  3. 9 Excludes2 entries — those conditions are not part of this code and may be reported additionally when documented. See the Excludes2 notes

Checklist rows are derived from this code's own official directives; the wording of each check is MedCoder editorial. The official notes themselves are in the sections each row links to.

Relationships & Classification

Other codes that name S72.04 or its code family, from the CMS ICD-10-CM tabular instructional notes. Tabular-note edges are stored at the code family level that carries each note.

Referenced by 3 Excludes1 notes across 2 chapters: M84.3 — Stress fracture (via S72.-), M84.4 — Pathological fracture, not elsewhere classified (via S72.-), S71 — Open wound of hip and thigh (via S72.-).

These codes’ tabular lists mark this diagnosis as mutually exclusive — not reported together unless the conditions are documented as unrelated.

Referenced by 1 Excludes2 note: S32 — Fracture of lumbar spine and pelvis (via S72.0.-).

These codes’ tabular lists name this diagnosis as distinct — both may be reported when both are documented.
