M96.A3 ICD-10-CM Code: Multiple fractures of ribs associated with chest compression and cardiopulmonary resuscitation

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

Coding at a Glance

Tabular directives
5 Excludes2

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)
  • MS-DRG 963 — OTHER MULTIPLE SIGNIFICANT TRAUMA WITH MCC (MDC 24)
  • MS-DRG 964 — OTHER MULTIPLE SIGNIFICANT TRAUMA WITH CC (MDC 24)
  • MS-DRG 965 — OTHER MULTIPLE SIGNIFICANT TRAUMA WITHOUT CC/MCC (MDC 24)

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 M96.A3 in the official ICD-10-CM tabular list, quoted as published.

Notes without a marker are published on M96.A3 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.

Source: inherited from M96

Coder workflow for M96.A3

MedCoder structured workflow — derived from this code’s own official record

Before you code M96.A3

  1. M96.A3’s title joins a condition with an associated condition or complication. Confirm each component is documented. Where the classification presumes the link through the “with” convention, only a provider statement that the conditions are unrelated defeats it. A combination code is assigned only when it fully identifies the documented conditions; a required second code for the stage, type or manifestation is still reported when the notes ask for it (Guidelines I.B.9, I.A.15).

Documentation check

The provider’s diagnostic statement
Codes are assigned from the provider’s documented diagnosis, not from clinical criteria, test values or a medication list (Guidelines I.A.19).
The associated condition or complication
Whether the associated condition the title names is documented; the “with” convention presumes some links, and a provider statement that the conditions are unrelated defeats it (Guidelines I.A.15).

Official instructions as workflow

  • Excludes2 — not part of M96.A3(5 notes)

    Coding workflow: The conditions named in this note are not included in M96.A3. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

Coding decision scenarios

Pattern scenarios for this code’s structure — decision rules, not clinical cases

Documentation: Only one of the components this code’s title joins is documented.

Coding question: Is M96.A3 supported?

Path: Review the code for the documented component on its own.

Reason: A combination code is assigned only when it fully identifies the documented conditions; otherwise the documented component takes its own code (Guidelines I.B.9).

Every row is derived from this code’s own record — its title, tabular notes, 7th-character family and same-category siblings — with fixed MedCoder wording; nothing is inferred about a patient. The official notes and guideline text are in the sections each row links to, and they control.

Code Overview

Multiple fractures of ribs associated with chest compression and cardiopulmonary resuscitation is a billable ICD-10-CM diagnosis code (M96.A3).

Indexed Clinical Terms (1)

Official source data — entries quoted as published, in the Index’s own lookup phrasing

Clinical term phrases from the official ICD-10-CM Index to Diseases and Injuries that map to this code. These are alphabetic-index entries shown as the Index writes them — lookup phrasing, not necessarily the wording of a final diagnosis.

Verify Before Coding

  • CC as a secondary diagnosis (FY2026). Can raise the stay's MS-DRG severity tier.

Relationships & Classification

MedCoder structured relationships — computed from published CMS and AHRQ datasets

Other codes that name M96.A3 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 12 Excludes1 notes: M40 — Kyphosis and lordosis (via M96.-), M86 — Osteomyelitis (via M96.-), M86-M90 — Other osteopathies (M86-M90) (via M96.-), M87 — Osteonecrosis (via M96.-), M88 — Osteitis deformans [Paget's disease of bone] (via M96.-), M89 — Other disorders of bone (via M96.-), M90 — Osteopathies in diseases classified elsewhere (via M96.-), M91 — Juvenile osteochondrosis of hip and pelvis (via M96.-), M91-M94 — Chondropathies (M91-M94) (via M96.-), M92 — Other juvenile osteochondrosis (via M96.-), M93 — Other osteochondropathies (via M96.-), M94 — Other disorders of cartilage (via M96.-).

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

Referenced by 11 Excludes2 notes across 2 chapters: M95 — Other acquired deformities of musculoskeletal system and connective tissue (via M96.-), T80 — Complications following infusion, transfusion and therapeutic injection (via M96.-), T80-T88 — Complications of surgical and medical care, not elsewhere classified (T80-T88) (via M96.-), T81 — Complications of procedures, not elsewhere classified (via M96.-), T82 — Complications of cardiac and vascular prosthetic devices, implants and grafts (via M96.-), T83 — Complications of genitourinary prosthetic devices, implants and grafts (via M96.-), T84 — Complications of internal orthopedic prosthetic devices, implants and grafts (via M96.-), T85 — Complications of other internal prosthetic devices, implants and grafts (via M96.-), T86 — Complications of transplanted organs and tissue (via M96.-), T87 — Complications peculiar to reattachment and amputation (via M96.-), T88 — Other complications of surgical and medical care, not elsewhere classified (via M96.-).

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

MS-DRG Grouper Relationships (FY2026)

Potential MS-DRG participation — not a DRG assignment.

CC — Complication or Comorbidity. Reported as a secondary diagnosis, this code raises the stay's MS-DRG severity tier — except when the principal diagnosis is one of 5 clinically related codes on its CMS exclusion list.

Named in the grouper logic of 6 MS-DRGs: DRG 564 (MDC 08), DRG 565 (MDC 08), DRG 566 (MDC 08), DRG 963 (MDC 24), DRG 964 (MDC 24), DRG 965 (MDC 24).

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

Same clinical process (MS-DRG)

Acts as CC — raises the severity of other admissions. CMS groups these diagnoses into one MS-DRG principal-diagnosis exclusion process — a CC/MCC on this list never raises severity when the principal diagnosis is also on it.
