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

Coding at a Glance

Tabular directives: 6 inclusion terms · 9 Excludes1 · 1 use-additional code
Risk adjustment: CMS-HCC V28: 2 categories · CMS-HCC V22 category 161 · CMS-HCC V22 category 18 · RxHCC V08 category 30 · RxHCC V08 category 311

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 637 — DIABETES WITH MCC (MDC 10)
MS-DRG 638 — DIABETES WITH CC (MDC 10)
MS-DRG 639 — DIABETES 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.

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)
HCC 383 — Chronic Ulcer of Skin, Except Pressure, Not Specified as Through to Bone or Muscle

Other models: CMS-HCC V22 HCC 161 · CMS-HCC V22 HCC 18 · RxHCC V08 HCC 30 · RxHCC V08 HCC 311

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

Coder workflow for E10.622

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

Before you code E10.622

E10.622’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: Diabetes with multiple complications →
Check the Excludes1 note: if the documentation supports a condition named there, do not simply proceed with E10.622. 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 E10.622’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.
ReviewE08, E09, O24.4, R73.9, P70.2, E13

Consider E10.622. 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.

Official instructions as workflow

Excludes1 — check before selecting E10.622(9 notes)
Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with E10.622: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.
CompareE08, E09, O24.4, R73.9, P70.2, E13
See the official tabular notes · Guidelines I.A.12.a
Use Additional Code — after identifying E10.622(1 note)
Coding workflow: Check whether the documentation supports the additional code(s) the note names, and report them with E10.622 when it does. Where the instruction is conditional (“if applicable”, “if known”), it applies only when the record documents the condition.
See the official tabular notes · Guidelines I.A.13

Coding decision scenarios

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

Documentation: Both the condition E10.622 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).

ReviewE08, E09, O24.4, R73.9, P70.2, E13

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

Coding question: Is E10.622 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 E10.622?

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).

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 E10.622 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 E10.-), I96 — Gangrene, not elsewhere classified (via E10.-), L89 — Pressure ulcer.

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

Referenced by 2 Code First instructions across 2 chapters: D84.81 — Immunodeficiency due to conditions classified elsewhere (via E10.-), L97 — Non-pressure chronic ulcer of lower limb, not elsewhere classified.

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 Code Also instruction: N76.82 — Fournier disease of vagina and vulva (via E10.-).

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

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 6 MS-DRGs: DRG 008 (MDC PRE), DRG 010 (MDC PRE), DRG 019 (MDC PRE), DRG 637 (MDC 10), DRG 638 (MDC 10), DRG 639 (MDC 10).

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

Same CMS-HCC risk category (V28)

CMS maps these diagnoses to the same Hierarchical Condition Categories (Diabetes with Chronic Complications, Chronic Ulcer of Skin, Except Pressure, Not Specified as Through to Bone or Muscle) for risk-adjusted payment.

Related risk categories

These categories interact through CMS's HCC hierarchy — one can suppress the other's risk-adjustment weight when both are present on a claim.

Atherosclerosis of Arteries of the Extremities with Ulceration or Gangrene, Pancreas Transplant Status, Diabetes with Severe Acute Complications, Diabetes with Glycemic, Unspecified, or No Complications, Pressure Ulcer of Skin with Necrosis Through to Muscle, Tendon, or Bone, Chronic Ulcer of Skin, Except Pressure, Through to Bone or Muscle, Pressure Ulcer of Skin with Full Thickness Skin Loss, Pressure Ulcer of Skin with Partial Thickness Skin Loss

Same clinical category (CCSR)

AHRQ's Clinical Classifications Software groups these diagnoses under the same clinical categories (Diabetes mellitus with complication, Diabetes mellitus, Type 1, Pressure ulcer of skin).

Same Index main term, other category

The ICD-10-CM Index to Diseases and Injuries files this code under the main term “Diabetes, diabetic”; these codes share that main term but sit in a different category of the Tabular List.
