S82.65XH ICD-10-CM Code: Nondisplaced fracture of lateral malleolus of left fibula, subsequent encounter for open fracture type I or II with delayed healing

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 559 — AFTERCARE, MUSCULOSKELETAL SYSTEM AND CONNECTIVE TISSUE WITH MCC (MDC 08)
  • MS-DRG 560 — AFTERCARE, MUSCULOSKELETAL SYSTEM AND CONNECTIVE TISSUE WITH CC (MDC 08)
  • MS-DRG 561 — AFTERCARE, MUSCULOSKELETAL SYSTEM AND CONNECTIVE TISSUE 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.

Code Overview

Nondisplaced fracture of lateral malleolus of left fibula, subsequent encounter for open fracture type I or II with delayed healing is a billable ICD-10-CM diagnosis code (S82.65H).

Official Tabular Instructional Notes

Sequencing, inclusion, and exclusion notes published for S82.65XH in the official ICD-10-CM tabular list.

Includes

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

  • fracture of malleolus inherited from S82

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.

Frequently Compared Codes

The official Excludes notes on S82.65XH name these codes. Each comparison page covers when the two can — or must not — be reported together.

Relationships & Classification

Other codes that name S82.65XH 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 (via S82.-), M84.4 (via S82.-), S81 (via S82.-).

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

Referenced by 13 Excludes2 notes: S72 (via S82.-), S82.4 (via S82.6.-), S90 (via S82.-), S90-S99 (via S82.-), S91 (via S82.-), S92 (via S82.-), S93 (via S82.-), S94 (via S82.-), S95 (via S82.-), S96 (via S82.-), S97 (via S82.-), S98 (via S82.-), S99 (via S82.-).

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

MS-DRG Grouper Relationships (FY2026)

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

Named in the grouper logic of 3 MS-DRGs: DRG 559 (MDC 08), DRG 560 (MDC 08), DRG 561 (MDC 08).

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