E89.5 ICD-10-CM Code: Postprocedural testicular hypofunction

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

Coding at a Glance

Tabular directives
1 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 643 — ENDOCRINE DISORDERS WITH MCC (MDC 10)
  • MS-DRG 644 — ENDOCRINE DISORDERS WITH CC (MDC 10)
  • MS-DRG 645 — ENDOCRINE DISORDERS WITHOUT CC/MCC (MDC 10)

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 E89.5 in the official ICD-10-CM tabular list, quoted as published.

Source: CMS/CDC — ICD-10-CM Tabular ListRelease: FY2026Effective: October 1, 2025

Notes without a marker are published on E89.5 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.

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).

Official instructions as workflow

  • Excludes2 — not part of E89.5(1 note)

    Coding workflow: The conditions named in this note are not included in E89.5. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

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.

Relationships & Classification

MedCoder structured relationships — computed from published CMS and AHRQ datasets

Other codes that name E89.5 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 1 Excludes1 note: E29.1 — Testicular hypofunction.

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

Referenced by 12 Excludes2 notes across 3 chapters: E36 — Intraoperative complications of endocrine system (via E89.-), T80 — Complications following infusion, transfusion and therapeutic injection (via E89.-), T80-T88 — Complications of surgical and medical care, not elsewhere classified (T80-T88) (via E89.-), T81 — Complications of procedures, not elsewhere classified (via E89.-), T82 — Complications of cardiac and vascular prosthetic devices, implants and grafts (via E89.-), T83 — Complications of genitourinary prosthetic devices, implants and grafts (via E89.-), T84 — Complications of internal orthopedic prosthetic devices, implants and grafts (via E89.-), T85 — Complications of other internal prosthetic devices, implants and grafts (via E89.-), T86 — Complications of transplanted organs and tissue (via E89.-), T87 — Complications peculiar to reattachment and amputation (via E89.-), T88 — Other complications of surgical and medical care, not elsewhere classified (via E89.-), Z90 — Acquired absence of organs, not elsewhere classified (via E89.-).

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.

FY2026 MS-DRG: not on the CMS CC/MCC list — as a secondary diagnosis this code does not change MS-DRG severity for that release.

Named in the grouper logic of 3 MS-DRGs: DRG 643 (MDC 10), DRG 644 (MDC 10), DRG 645 (MDC 10).

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