Decision Criteria

clinical Criteria

  • Biopsy confirms ADH without upgrade to DCIS or malignancy.

coding Criteria

  • Do not use D05.10 unless DCIS is confirmed.

Applicable To

  • Atypical ductal hyperplasia

Excludes

  • Ductal carcinoma in situ (D05.-)

Clinical Validation Requirements

  • Biopsy confirmation of atypical ductal hyperplasia
  • Size ≤2 mm with ≤2 involved duct spaces

Code-Specific Risks

  • Incorrectly coding as DCIS or malignancy

Coding Notes

  • Ensure documentation specifies size, calcifications, and laterality.

Ancillary Codes

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

Inconclusive mammogram pre-biopsy

R92.2
Use when mammogram shows cluster microcalcifications, BIRADS 4.

Encounter for screening mammogram

Z12.31
Use when screening mammogram is performed asymptomatically.

Differential Codes

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

Intracystic carcinoma in situ of unspecified breast

D05.10
Use only if surgical excision confirms DCIS.

Malignant neoplasm of unspecified site of right female breast

C50.911
Never use for ADH alone.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Atypical Ductal Hyperplasia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code N60.89.

Impact

Clinical: May lead to misclassification as DCIS., Regulatory: Increases risk of audit for incorrect coding., Financial: Potential for incorrect reimbursement.

Mitigation Strategy

Ensure pathology reports include size and extent details.

Impact

Reimbursement: Incorrect coding can lead to inappropriate DRG assignment., Compliance: May trigger audits for incorrect cancer coding., Data Quality: Misrepresents patient condition in medical records.

Mitigation Strategy

Use N60.89 for ADH unless DCIS is confirmed.

Impact

Incorrect coding of ADH as DCIS can lead to audits.

Mitigation Strategy

Ensure documentation clearly differentiates ADH from DCIS.

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.

Documentation Templates for Atypical Ductal Hyperplasia

Use these documentation templates to ensure complete and accurate documentation for Atypical Ductal Hyperplasia. These templates include all required elements for proper coding and billing.

Biopsy-confirmed ADH

Specialty: Pathology

Required Elements

  • Biopsy results
  • Size and extent of lesion
  • Immunohistochemical staining results

Example Documentation

Biopsy confirms atypical ductal hyperplasia, 1.8 mm focus, cribriform pattern, ER+ (Allred score 7/8).

Examples: Poor vs. Good Documentation

Poor Documentation Example
Atypical cells present.
Good Documentation Example
ADH confirmed: 1.8 mm focus, cribriform pattern, ER+ (Allred score 7/8).
Explanation
The good example provides specific size, pattern, and receptor status, supporting accurate coding.
