What you need to know

Source: CMS/NCHS Official ICD-10-CM tabular notes, quoted. From the CMS/NCHS tabular list for the release in force. A note the category or block publishes applies to this code too; the Instructions section marks which is which.

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 v44, Appendix B.

  • MS-DRG 919 — COMPLICATIONS OF TREATMENT WITH MCC (MDC 21)
  • MS-DRG 920 — COMPLICATIONS OF TREATMENT WITH CC (MDC 21)
  • MS-DRG 921 — COMPLICATIONS OF TREATMENT WITHOUT CC/MCC (MDC 21)

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.

Coder workflow for E89.838

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

Before you code E89.838

  1. “Other” (NEC) means the condition is specified in the record but no dedicated code captures it. Confirm the documented form is not one a sibling code names before settling on E89.838; if the record states no specifics at all, the unspecified sibling applies instead. “Other” codes are for documented conditions the classification gives no specific code; “unspecified” codes are for records lacking the detail (Guidelines I.A.9.a, I.A.9.b).

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 conditions the Use Additional Code note names
Reported with this code when documented; a conditional instruction (“if applicable”, “if known”) applies only when the record supports it.
Any detail beyond this code’s title
What the record states that a more specific sibling code would capture — or its absence, which itself supports the unspecified code.

Official instructions as workflow

  • Excludes2 — not part of E89.838(1 note)

    Coding workflow: The conditions named in this note are not included in E89.838. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

    CompareE36.0, E36.1, E36.8

    See the official tabular notes · Guidelines I.A.12.b

  • Use Additional Code — after identifying E89.838(1 note)

    Coding workflow: Check whether the documentation supports the additional code(s) the note names, and report them with E89.838 when it does. Where the instruction is conditional (“if applicable”, “if known”), it applies only when the record documents the condition.

Coding decision scenarios

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

Documentation: A condition the Use Additional Code note names is documented.

Coding question: Is a second code reported with E89.838?

Path: Review the Use Additional Code note and the code it names.

Reason: The additional code is reported when the record documents the condition; a conditional instruction applies only when its condition is met (Guidelines I.A.13).

ReviewE16.A

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.

    Distinct conditions — both may be reported.

    A distinct condition — both may be reported when both are documented.

Relationships & Classification

MedCoder-derived relationships — computed from published CMS and AHRQ datasets

Other codes that name E89.838 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 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 (FY2027)

Potential MS-DRG participation — not a DRG assignment.

FY2027 MS-DRG: 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 26 clinically related codes on its CMS exclusion list.

Named in the grouper logic of 3 MS-DRGs: DRG 919 (MDC 21), DRG 920 (MDC 21), DRG 921 (MDC 21).

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

Related Codes

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.
