L82-L82.9Primary Range

Seborrheic Keratosis

Actinic Keratosis

Used for coding actinic keratosis with verrucous features.

Viral Warts

Used if verrucous features are due to HPV.

CodeDescriptionWhen to UseKey Documentation
L82.1Other seborrheic keratosisUse when biopsy confirms seborrheic keratosis with verrucous features.
  • Dermoscopy showing milia-like cysts and comedo-like openings
  • Histology confirming horn pseudocysts without atypia
L57.0Actinic keratosisUse when biopsy confirms actinic keratosis with verrucous features.
  • Histology showing basal keratinocyte atypia and solar elastosis

Clinical Decision Support

Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Billable Code

Decision Criteria

clinical Criteria

  • Biopsy confirms seborrheic keratosis without atypia.

coding Criteria

  • Use L82.1 for non-inflamed lesions.

documentation Criteria

  • Document 'stuck-on' appearance and absence of atypia.

Applicable To

  • Non-inflamed seborrheic keratosis with verrucous morphology

Excludes

  • Inflamed seborrheic keratosis (L82.0)

Clinical Validation Requirements

  • Dermoscopy showing milia-like cysts and comedo-like openings
  • Histology confirming horn pseudocysts without atypia

Code-Specific Risks

  • Incorrectly coding inflamed lesions under L82.1

Coding Notes

  • Ensure histological confirmation to avoid misclassification.

Ancillary Codes

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

UV radiation exposure

W89.1XXA
Use when actinic etiology is confirmed.

Tanning bed exposure

Z77.22
Use if relevant to the patient's history.

Differential Codes

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

Actinic keratosis

L57.0
Presence of solar elastosis and basal layer atypia.

Other viral warts

B07.8
Histology showing koilocytic changes.

Other seborrheic keratosis

L82.1
Lack of solar damage and atypia.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Verrucous Keratosis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code L82.1.

Impact

Clinical: May lead to incorrect treatment decisions., Regulatory: Non-compliance with documentation standards., Financial: Potential for claim denials.

Mitigation Strategy

Ensure detailed lesion descriptions., Confirm diagnosis with biopsy.

Impact

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

Mitigation Strategy

Use L82.0 for inflamed seborrheic keratosis.

Impact

Misclassification of verrucous keratosis can lead to audit findings.

Mitigation Strategy

Ensure biopsy confirmation and detailed documentation.

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 Verrucous Keratosis

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

Verrucous keratosis diagnosis

Specialty: Dermatology

Required Elements

  • Lesion location
  • Lesion size
  • Morphology
  • Dermoscopy findings
  • Biopsy results

Example Documentation

Location: Left preauricular area; Size: 7mm; Morphology: Hyperpigmented verrucous plaque with 'cracked mud' surface; Dermoscopy: Comedo-like openings, milia-like cysts, no pigment network; Biopsy: Orthokeratosis, acanthosis, horn pseudocysts. No atypia or koilocytes. Impression: Verrucous seborrheic keratosis (L82.1); Plan: Cryotherapy with 2 freeze-thaw cycles (17110).

Examples: Poor vs. Good Documentation

Poor Documentation Example
Verrucous lesion on arm
Good Documentation Example
3x4mm hyperkeratotic verrucous plaque on right dorsal forearm with classic 'pasted-on' appearance, biopsy confirms seborrheic keratosis without atypia
Explanation
The good example provides specific lesion details and biopsy confirmation, improving coding accuracy.
