Billable Code

Decision Criteria

clinical Criteria

  • Presence of palpable purpura and IgA deposition

coding Criteria

  • Platelet count must be normal

documentation Criteria

  • Document specific symptoms and lab findings

Applicable To

  • Henoch-Schönlein purpura
  • IgA vasculitis

Excludes

  • Hypersensitivity angiitis (M31.0)
  • Lupus panniculitis (L93.2)

Clinical Validation Requirements

  • Palpable purpura
  • IgA deposition on biopsy
  • Normal platelet count

Code-Specific Risks

  • Confusion with thrombocytopenic purpura (D69.3)
  • Incorrect use without palpable purpura documentation

Coding Notes

  • Ensure documentation specifies 'palpable purpura' and check for renal involvement.

Ancillary Codes

Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Recurrent and persistent hematuria

N02.8
Use for renal involvement with hematuria in allergic purpura.

Differential Codes

Alternative codes to consider when ruling out similar conditions to the primary diagnosis.

Immune thrombocytopenic purpura

D69.3
Use if platelet count is below 150,000/mm³.

Hypersensitivity angiitis

M31.0
Use if biopsy shows necrotizing vasculitis without IgA deposits.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Allergic Purpura to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code D69.0.

Impact

Clinical: May lead to misdiagnosis of thrombocytopenic purpura., Regulatory: Non-compliance with coding standards., Financial: Potential claim denials due to incorrect coding.

Mitigation Strategy

Ensure lab results are included in the patient's chart., Verify platelet count before coding.

Impact

Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with ICD-10 coding guidelines., Data Quality: Inaccurate clinical data reporting.

Mitigation Strategy

Require explicit 'palpable' descriptor in documentation.

Impact

Risk of coding allergic purpura as thrombocytopenic purpura.

Mitigation Strategy

Verify platelet count and clinical findings before coding.

Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.

Emergency Department Presentation

Specialty: Pediatrics

Required Elements

  • History of palpable purpura
  • Abdominal pain
  • Arthralgia
  • Normal platelet count

Example Documentation

**HPI**: 8yo male with 3-day history of palpable purpura on legs/buttocks, colicky abdominal pain, and knee swelling. No bleeding gums or thrombocytopenia (plt 320,000/mm³). **PE**: Non-blanching purpura >3mm on lower extremities, joint tenderness. **Assessment**: Allergic purpura (D69.0) with arthritis and abdominal involvement. **Plan**: Monitor renal function; urinalysis q48h.

Examples: Poor vs. Good Documentation

Poor Documentation Example
**HPI**: Rash on legs. **Assessment**: Purpura.
Good Documentation Example
**HPI**: 8yo male with 3-day history of palpable purpura on legs/buttocks, colicky abdominal pain, and knee swelling. No bleeding gums or thrombocytopenia (plt 320,000/mm³).
Explanation
The good example provides specific symptoms and lab results, supporting the diagnosis of allergic purpura.
