What is ICD-10 code D69.0?

D69.0 is the ICD-10-CM diagnosis code for Allergic purpura. It belongs to the ICD-10-CM chapter for diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism (d50-d89). D69.0 is a billable code, meaning it can be reported on a claim as a primary or secondary diagnosis when supported by documentation. D69.0 is part of the FY2026 ICD-10-CM code set published by the CMS National Center for Health Statistics and used on Medicare, Medicaid, and commercial claims in the United States.

Yes. D69.0 is a billable ICD-10-CM code that can be reported on professional and institutional claims as a primary or secondary diagnosis when the provider documentation supports the specific condition described. Billable codes in ICD-10-CM are coded to the highest level of specificity available for the documented diagnosis. D69.0 is current for fiscal year 2026 and remains in the active CMS ICD-10-CM code set published by the National Center for Health Statistics.

Which HCC does D69.0 map to under V28?

D69.0 has no payable CMS-HCC V28 mapping in the final FY2026 CMS file.

What RAF reference is published for D69.0?

D69.0 has no V28 reference coefficient because the final FY2026 source verifies no payable V28 mapping.

What is the V28 vs V24 difference for D69.0?

D69.0 has verified no payable V28 mapping in the final FY2026 source. Select a historical effective period before making any V24 comparison.

What documentation supports D69.0?

Verify the documentation specifies this is allergic purpura (also known as IgA vasculitis or Henoch-Schönlein purpura) rather than other types of purpura, as the cause determines the correct code Document any systemic involvement (joint pain, abdominal symptoms, kidney involvement) as these may require additional codes and affect severity assessment D69.0 is not a CMS-HCC V28 payment code in the verified current source, so MEAT is not the payment hook. Documentation still has to support the diagnosis if you report it.

Allergic purpura

Allergic purpura is a condition where small blood vessels in the skin become inflamed due to an allergic reaction, causing purple or red spots (purpura) to appear on the skin. This is typically a non-serious condition that resolves on its own, though it can occasionally affect other organs.

Buddy Documentation Tip

HCC Buddy guidance

Document the characteristic non-thrombocytopenic palpable purpura distribution, associated symptoms (joint pain, abdominal pain, hematuria/proteinuria), urinalysis results, renal function testing, and skin biopsy findings showing IgA deposits when performed.

Record any gastrointestinal or renal complications and treatment approach.

MEAT Support

HCC Buddy guidance

Record any gastrointestinal or renal complications and treatment approach.

Audit Caution

HCC Buddy guidance

Platelet count is normal in allergic purpura — if thrombocytopenia is present, reconsider the diagnosis.

In adults, the renal manifestations are often more severe and should be coded separately with appropriate N-codes.

Do not confuse with thrombocytopenic purpura (D69.3, D69.4x) which involves low platelet counts.

Common Mistakes

HCC Buddy guidance

D69.2 (Other nonthrombocytopenic purpura) — non-allergic causes of purpura with normal platelets

D69.3 (Immune thrombocytopenic purpura) — platelet-mediated purpura with thrombocytopenia

M31.0 (Hypersensitivity angiitis) — other forms of vasculitis

N05.x (Unspecified nephritic syndrome) — may be needed for renal involvement.

Is D69.0 an HCC code?

D69.0 is not in the CMS-HCC V28 or V24 community payment model. D69.0 has a separate mapping under the CMS-HCC ESRD model (HCC 48 (Coagulation Defects and Other Specified Hematological Disorders)); the applicable result needs member context.

HCC Category Mapping

ESRDHCC 48, Coagulation Defects and Other Specified Hematological Disorders

Not separately weighted

These are source-labeled model coefficients, not member totals. A category may still be removed by hierarchy or model cleanup rules. Weights are not directly comparable across models: CMS-HCC V28 and V24 use Community, Non-Dual, Aged; ESRD uses the dialysis continuing-enrollee model; RxHCC is the Part D continuing-enrollee, non-low-income, aged weight (a larger scale than CMS-HCC). ACA/HHS has no single weight — it varies by metal level. Actual per-patient RAF contribution depends on member context, hierarchy and cleanup rules, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains available for historical review.

MEAT Criteria for D69.0

For D69.0 to count as a valid HCC diagnosis in a given encounter, the provider's documentation must show MEAT: Monitor, Evaluate, Assess, or Treat. A diagnosis from a prior year does not carry forward automatically, it has to be re-documented and supported each calendar year.

MMonitor: signs, symptoms, disease progression, or lab trending documented in the note
EEvaluate: test results, medication response, or physical findings reviewed by the provider
AAssess: explicit mention in the assessment or plan with acknowledgment of status
TTreat: medication, referral, procedure, therapy, or counseling tied to the diagnosis

Only one of M/E/A/T is required to support the code, but the documentation must be specific enough to show that the provider actually addressed D69.0 during that encounter, not just copy-forwarded from a problem list.

What This Code Means

D69.0 is the ICD-10-CM diagnosis code for allergic purpura. Allergic purpura is a condition where small blood vessels in the skin become inflamed due to an allergic reaction, causing purple or red spots (purpura) to appear on the skin. This is typically a non-serious condition that resolves on its own, though it can occasionally affect other organs. D69.0 sits in the ICD-10-CM chapter for diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism (d50-d89), within the section covering coagulation defects, purpura and other hemorrhagic conditions (d65-d69).

D69.0 has no mapping under the CMS-HCC V28 or V24 community payment models. D69.0 has a separate mapping under the CMS-HCC ESRD model (HCC 48 (Coagulation Defects and Other Specified Hematological Disorders)); the applicable result needs member context. Do not assign V28 risk adjustment value from this page; verify the applicable model and payment year before using this code for risk adjustment.

Verify the documentation specifies this is allergic purpura (also known as IgA vasculitis or Henoch-Schönlein purpura) rather than other types of purpura, as the cause determines the correct code.

HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for D69.0 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•Verify the documentation specifies this is allergic purpura (also known as IgA vasculitis or Henoch-Schönlein purpura) rather than other types of purpura, as the cause determines the correct code
•Document any systemic involvement (joint pain, abdominal symptoms, kidney involvement) as these may require additional codes and affect severity assessment

Clinical Significance

Allergic purpura, also known as Henoch-Schonlein purpura or IgA vasculitis, is an immune-mediated small vessel vasculitis characterized by palpable purpura predominantly on the lower extremities, arthritis, abdominal pain, and renal involvement. It is most common in children but can occur in adults with typically more severe renal manifestations. Long-term prognosis depends primarily on the degree of renal involvement.

Documentation Requirements

✓Document the characteristic non-thrombocytopenic palpable purpura distribution, associated symptoms (joint pain, abdominal pain, hematuria/proteinuria), urinalysis results, renal function testing, and skin biopsy findings showing IgA deposits when performed.
✓Record any gastrointestinal or renal complications and treatment approach.
