Decision Criteria

clinical Criteria

  • Presence of symmetrical hyperpigmented macules on the face

documentation Criteria

  • Documentation of hormonal or UV exposure as exacerbating factors

Applicable To

  • Melasma
  • Chloasma

Excludes

  • Post-inflammatory hyperpigmentation (L81.0)
  • Café-au-lait spots (L81.3)

Clinical Validation Requirements

  • Symmetrical facial hyperpigmentation
  • Exclusion of drug-induced pigmentation
  • Wood's lamp examination showing epidermal pigmentation

Code-Specific Risks

  • Incorrectly using for post-inflammatory hyperpigmentation
  • Not documenting specific distribution patterns

Coding Notes

  • Ensure documentation specifies the symmetrical nature and sun-exposed distribution of pigmentation.

Ancillary Codes

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

Other specified pregnancy-related conditions

O26.89
Use when melasma is related to pregnancy.

Other long term (current) drug therapy

Z79.899
Use when melasma is exacerbated by hormonal contraceptives.

Differential Codes

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

Post-inflammatory hyperpigmentation

L81.0
Use L81.0 if pigmentation follows an inflammatory process and lacks symmetry typical of melasma.

Café-au-lait spots

L81.3
Use L81.3 for congenital, non-symmetrical pigmentation spots.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Melasma to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code L81.1.

Impact

Clinical: Inadequate clinical picture for diagnosis., Regulatory: Potential for audit issues., Financial: Risk of claim denials due to insufficient documentation.

Mitigation Strategy

Always ask about and document sun exposure and hormonal therapy., Use templates to ensure comprehensive documentation.

Impact

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

Mitigation Strategy

Use L81.0 if pigmentation is due to an inflammatory process.

Impact

Audits may target insufficiently documented cases of melasma.

Mitigation Strategy

Ensure all documentation includes detailed descriptions of pigmentation patterns and exacerbating factors.

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 Melasma

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

Melasma exacerbated by oral contraceptives

Specialty: Dermatology

Required Elements

  • Symmetrical hyperpigmentation
  • History of hormonal contraceptive use
  • Wood's lamp examination findings

Example Documentation

Patient presents with symmetrical brown macules on the cheeks and forehead. History of oral contraceptive use. Wood's lamp confirms epidermal pigmentation.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Patient has facial discoloration.
Good Documentation Example
Symmetrical hyperpigmented macules on bilateral malar cheeks, worsening with sun exposure.
Explanation
The good example provides specific details about the distribution and exacerbating factors, supporting the use of L81.1.
