Excludes

  • Breast engorgement of newborn (P83.4)
  • Breast lump (R92.2)

Clinical Validation Requirements

  • Duration >12 months in adolescents/6 months in adults
  • Negative β-hCG, testosterone <300 ng/dL, estradiol >40 pg/mL

Code-Specific Risks

  • Confusion with pseudogynecomastia
  • Incorrect sequencing with underlying causes

Coding Notes

  • Ensure clinical documentation supports the diagnosis with lab and imaging evidence.

Ancillary Codes

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

Hypogonadism

E23.0
Use when gynecomastia is due to hormonal imbalance.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Gynecomastia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code N62.

Impact

Clinical: May lead to misdiagnosis if not clinically correlated., Regulatory: Non-compliance with clinical diagnosis standards., Financial: Potential claim denials due to insufficient documentation.

Mitigation Strategy

Ensure clinical evaluation corroborates pathology findings., Document clinical findings thoroughly.

Impact

Reimbursement: Incorrect sequencing can lead to claim denials., Compliance: Non-compliance with ICD-10 coding guidelines., Data Quality: Inaccurate clinical data representation.

Mitigation Strategy

Always code the underlying cause first, followed by N62.

Impact

Inadequate documentation can lead to audit failures.

Mitigation Strategy

Ensure all criteria for surgical intervention are documented.

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.

  • History of present illness
  • Physical exam findings
  • Laboratory results
  • Treatment plan

Example Documentation

Reason: Evaluation of persistent gynecomastia. HPI: 24yo M with bilateral breast enlargement x14mo. No nipple discharge. Failed 6mo of anastrozole 1mg daily. Current bra cup size: B. Exam: Symmetric 5cm firm subareolar masses. No axillary lymphadenopathy. Labs: Total testosterone 280 ng/dL (RR:300-1000), Estradiol 45 pg/mL (RR: <40), LH 8 mIU/mL (RR:1.7-8.6). Plan: 1. MRI pelvis to evaluate Leydig cell tumors, 2. Trial clomiphene 50mg PO daily.
