S22.43XS ICD-10-CM Code: Multiple fractures of ribs, bilateral, sequela

Billing Status: YES. This is a valid, specific, and billable ICD-10-CM reference.

Inpatient Payment Groups (MS-DRG)

MS-DRGs this diagnosis helps define, as principal or secondary, per the CMS ICD-10-CM/PCS MS-DRG Definitions Manual v43.0, Appendix B.

  • MS-DRG 551 — MEDICAL BACK PROBLEMS WITH MCC (MDC 08)
  • MS-DRG 552 — MEDICAL BACK PROBLEMS WITHOUT 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.

Official Registry Overview & Definition

Multiple fractures of ribs, bilateral, sequela is a billable ICD-10-CM diagnosis code (S22.43S).

Official Tabular Instructional Notes

Sequencing, inclusion, and exclusion notes published for S22.43XS in the official ICD-10-CM tabular list.

Includes

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

  • fracture of thoracic neural arch
  • fracture of thoracic spinous process
  • fracture of thoracic transverse process
  • fracture of thoracic vertebra
  • fracture of thoracic vertebral arch
  • injuries of breast
  • injuries of chest (wall)
  • injuries of interscapular area

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).

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.

  • Code first, if applicable, spinal cord injury (S24.0-, S24.1-)

Code Also

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

  • Code also, if applicable, any associated condition such as:
  • injury of intrathoracic organ (S27.-)
  • traumatic hemopneumothorax (S27.2)
  • traumatic hemothorax (S27.1-)
  • traumatic pneumothorax (S27.0)

Frequently Compared Codes

The official Excludes notes on S22.43XS name these codes. Each comparison page covers when the two can — or must not — be reported together.
