Coding at a Glance

Tabular directives: 6 inclusion terms · 7 Excludes1 · 5 use-additional codes
Risk adjustment: CMS-HCC V28: 1 category · CMS-HCC V22 category 18 · RxHCC V08 category 30

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 008 — SIMULTANEOUS PANCREAS AND KIDNEY TRANSPLANT (MDC PRE)
MS-DRG 010 — PANCREAS TRANSPLANT (MDC PRE)
MS-DRG 019 — SIMULTANEOUS PANCREAS AND KIDNEY TRANSPLANT WITH HEMODIALYSIS (MDC PRE)
MS-DRG 073 — CRANIAL AND PERIPHERAL NERVE DISORDERS WITH MCC (MDC 01)
MS-DRG 074 — CRANIAL AND PERIPHERAL NERVE DISORDERS WITHOUT MCC (MDC 01)

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.

Risk Adjustment (CMS-HCC)

Payment categories this diagnosis maps to under CMS-HCC V28, payment year 2026.

HCC 37 — Diabetes with Chronic Complications (supersedes HCC 38)

Other models: CMS-HCC V22 HCC 18 · RxHCC V08 HCC 30

Risk scores depend on the enrollee's full accepted diagnosis set and segment; a category mapping alone does not determine payment.

Coder workflow for E13.43

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

Before you code E13.43

“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 E13.43; 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).
See the relationships section · Guide: Other vs unspecified (NEC vs NOS) →
E13.43’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).
Guide: Combination codes →
Confirm the documented diabetes type or cause (the E08–E13 categories are separated by it) and every documented complication or manifestation; the code is built from the type first and the complication second. Then work the category’s Use Additional Code notes for medication and control status. Type 2 is the default only when the type is not documented, and insulin or other medication use does not by itself establish the type (Guidelines I.C.4.a.2, I.C.4.a.3).
Guide: Secondary diabetes (E08, E09, E13) →
Check the Excludes1 note: if the documentation supports a condition named there, do not simply proceed with E13.43. Excludes1 conditions are not reported together with this code unless the record shows they are unrelated (Guidelines I.A.12.a).
See the official tabular notes

Choose the right path

Does the documentation support a condition named in E13.43’s Excludes1 note?
Yes → Do not simply proceed: review the excluded code. Both are reported only when the record shows the two conditions are unrelated.
No → Continue.
ReviewE10, E08, E09, O24.4, P70.2

Consider E13.43. Then work the Use Additional Code note, and confirm the code is valid for the date of service in the Verify section.

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).
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.
Diabetes type or cause, each complication, and medication use: The type is documented, not inferred from medication (Guidelines I.C.4.a.3); each documented complication takes its own combination code.
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

Excludes1 — check before selecting E13.43(7 notes)
Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with E13.43: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.
CompareE10, E08, E09, O24.4, P70.2
See the official tabular notes · Guidelines I.A.12.a
Use Additional Code — after identifying E13.43(5 notes)
Coding workflow: Check whether the documentation supports the additional code(s) the note names, and report them with E13.43 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: Both the condition E13.43 describes and a condition named in its Excludes1 note are documented for the same encounter.

Coding question: Can both codes be reported?

Path: Review the Excludes1 note and the excluded code, and look for a provider statement on whether the two conditions are related.

Reason: Excludes1 means the two are not coded together; the exception is when the record shows the conditions are unrelated to each other (Guidelines I.A.12.a).

ReviewE10, E08, E09, O24.4, P70.2

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

Coding question: Is E13.43 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).

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

Coding question: Is a second code reported with E13.43?

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).

Official Coding Guidelines

Official source data — quoted verbatim from the CMS/NCHS Official Guidelines

Verbatim excerpts from the ICD-10-CM Official Guidelines for Coding and Reporting (CMS/NCHS) that govern this code.

Chapter 4: Endocrine, Nutritional, and Metabolic Diseases (E00 -E89)

a. Diabetes mellitus The diabetes mellitus codes are combination codes that include the type of diabetes mellitus, the body system affected, and the complications affecting that body system. As many codes within a particular category as are necessary to describe all of the complications of the disease may be used. They should be sequenced based on the reason for a particular encounter. Assign as many codes from categories E08 – E13 as needed to identify all of the associated conditions that the patient has.

Chapter 4: Endocrine, Nutritional, and Metabolic Diseases (E00 -E89)

6) Secondary diabetes mellitus Codes under categories E08, Diabetes mellitus due to underlying condition, E09, Drug or chemical induced diabetes mellitus, and E13, Other specified diabetes mellitus, identify complications/manifestations associated with secondary diabetes mellitus. Secondary diabetes is always caused by another condition or event (e.g., cystic fibrosis, malignant neoplasm of pancreas, pancreatectomy, adverse effect of drug, or poisoning).

Chapter 4: Endocrine, Nutritional, and Metabolic Diseases (E00 -E89)

(b) Assigning and sequencing secondary diabetes codes and its causes The sequencing of the secondary diabetes codes in relationship to codes for the cause of the diabetes is based on the Tabular List instructions for categories E08, E09 and E13.

Chapter 4: Endocrine, Nutritional, and Metabolic Diseases (E00 -E89)

(i) Secondary diabetes mellitus due to pancreatectomy For postpancreatectomy diabetes mellitus (lack of insulin due to the surgical removal of all or part of the pancreas), assign code E89.1, Postprocedural hypoinsulinemia. Assign a code from category E13 as the principal or first- listed diagnosis and a code from subcategory Z90.41, Acquired absence of pancreas, as an additional code. (ii) Secondary diabetes due to drugs Secondary diabetes may be caused by an adverse effect of correctly administered medications, poisoning or sequela of poisoning. See section I.C.19.e. for coding of adverse effects and poisoning, and section I.C.20 for external cause code reporting.

Chapter 15: Pregnancy, Childbirth, and the Puerperium (O00-O9A)

g. Diabetes mellitus in pregnancy Diabetes mellitus is a significant complicating factor in pregnancy. Pregnant patients who are diabetic should be assigned a code from category O24, Diabetes mellitus in pregnancy, childbirth, and the puerperium, first, followed by the appropriate diabetes code(s) (E08-E13) from Chapter 4.

Relationships & Classification

MedCoder structured relationships — computed from published CMS and AHRQ datasets

Other codes that name E13.43 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.

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

Referenced by 3 Excludes2 notes across 3 chapters: H35 — Other retinal disorders (via E13.-), I96 — Gangrene, not elsewhere classified (via E13.-), K31 — Other diseases of stomach and duodenum.

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

Referenced by 3 Code First instructions across 3 chapters: D84.81 — Immunodeficiency due to conditions classified elsewhere (via E13.-), E89.1 — Postprocedural hypoinsulinemia (via E13.-), K31.84 — Gastroparesis.

Each of these codes carries a Code First note naming this condition — when that code is reported, THIS code is sequenced first, ahead of it.

Referenced by 1 Use Additional Code instruction: Z90.41 — Acquired absence of pancreas (via E13.-).

These codes instruct coders to additionally report this code when it applies.

Referenced by 1 Code Also instruction: N76.82 — Fournier disease of vagina and vulva (via E13.-).

These codes suggest coding this condition alongside when both are present.
