Inpatient Payment Groups (MS-DRG)

Potential MS-DRG participation — not a DRG assignment.

MS-DRGs this diagnosis helps define, as principal or secondary, per the CMS ICD-10-CM/PCS MS-DRG Definitions Manual v43, Appendix B.

  • MS-DRG 564 — OTHER MUSCULOSKELETAL SYSTEM AND CONNECTIVE TISSUE DIAGNOSES WITH MCC (MDC 08)
  • MS-DRG 565 — OTHER MUSCULOSKELETAL SYSTEM AND CONNECTIVE TISSUE DIAGNOSES WITH CC (MDC 08)
  • MS-DRG 566 — OTHER MUSCULOSKELETAL SYSTEM AND CONNECTIVE TISSUE DIAGNOSES WITHOUT CC/MCC (MDC 08)

A diagnosis appearing in a group's logic does not by itself determine the DRG assigned to a stay; the grouper uses the full claim.

Coding instructions

Official Tabular Instructional Notes: the inclusion, exclusion and sequencing notes published for S32.19XK in the official ICD-10-CM tabular list, quoted as published.

Notes without a marker are published on S32.19XK itself; “inherited from” names the category or block whose note applies here.

Includes

Conditions the official ICD-10-CM tabular list includes under this code.

  • fracture of lumbosacral neural arch inherited from S32
  • fracture of lumbosacral spinous process inherited from S32
  • fracture of lumbosacral transverse process inherited from S32
  • fracture of lumbosacral vertebra inherited from S32
  • fracture of lumbosacral vertebral arch inherited from S32
  • injuries to the abdominal wall inherited from S30-S39

  • injuries to the flank inherited from S30-S39
  • injuries to the groin inherited from S30-S39

Excludes1 — Not Coded Here

Conditions generally not reported together with this code (Excludes1) -- an error unless the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).

Source: inherited from S32

Excludes2 — Not Included Here

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

Code First

Underlying conditions that must be sequenced before this code.

  • any associated spinal cord and spinal nerve injury (S34.-)

Source: inherited from S32

Code Also

Additional codes that may be required to fully describe the encounter.

  • any associated fracture of pelvic ring (S32.8-)

Source: inherited from S32.1

7th Character Guide

"The appropriate 7th character is to be added to each code from category S32"

  • A — initial encounter for closed fracture
  • B — initial encounter for open fracture
  • D — subsequent encounter for fracture with routine healing
  • G — subsequent encounter for fracture with delayed healing
  • K — subsequent encounter for fracture with nonunion (this page’s code)
  • 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.

Character meanings are CMS's official 7th-character extensions for this family, as carried in each variant code's official description; variant codes are registry rows. The explanation of how the encounter character is assigned is MedCoder editorial, distinct from the official content above it.

Code Overview

Other fracture of sacrum, subsequent encounter for fracture with nonunion is a billable ICD-10-CM diagnosis code (S32.19XK).

MedCoder summary Summary composed by MedCoder from this code's official ICD-10-CM record. The tabular instructional notes themselves appear verbatim below.

Official Coding Guidelines

Verbatim excerpts from the ICD-10-CM Official Guidelines for Coding and Reporting (CMS/NCHS) that govern this code.

Chapter 19: Injury, poisoning, and certain other consequences of external causes (S00-T88)

c. Coding of Traumatic Fractures The principles of multiple coding of injuries should be followed in coding fractures. Fractures of specified sites are coded individually by site in accordance with both the provisions within categories S02, S12, S22, S32, S42, S49, S52, S59, S62, S72, S79, S82, S89, S92 and the level of detail furnished by medical record content.

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. Sequencing: 1 Code First instruction — the underlying condition is sequenced before this code when present. See the Code First notes
  3. 1 Code Also note — a second code may apply; the guidelines leave its sequencing to the circumstances of the encounter. See the Code Also notes
  4. 1 Excludes1 entry — codes named there are generally not reported together with this code (Guidelines I.A.12.a). See the Excludes1 notes
  5. 7 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.

Verify Before Coding

Relationships & Classification

Other codes that name S32.19XK 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: M48.5 — Collapsed vertebra, not elsewhere classified (via S32.-), M84.3 — Stress fracture (via S32.-), M84.4 — Pathological fracture, not elsewhere classified (via S32.-).

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: S31 — Open wound of abdomen, lower back, pelvis and external genitals (via S32.1.-).

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

Referenced by 1 Use Additional Code instruction: S38.1 — Crushing injury of abdomen, lower back, and pelvis (via S32.-).

These codes instruct coders to additionally report this code when it applies.

Referenced by 1 Code Also instruction: S32.8 — Fracture of other parts of pelvis (via S32.1.-).

These codes suggest coding this condition alongside when both are present.

MS-DRG Grouper Relationships (FY2026)

Not on the CMS CC/MCC list — as a secondary diagnosis this code does not change MS-DRG severity.

Potential MS-DRG participation — not a DRG assignment.

Named in the grouper logic of 3 MS-DRGs: DRG 564 (MDC 08), DRG 565 (MDC 08), DRG 566 (MDC 08).

From the CMS MS-DRG Definitions Manual (Appendices B and C). Actual DRG assignment depends on the complete claim.
