ICD10 code of Pemphigus and ICD9 code

The primary ICD-10 code for Pemphigus is L10, with specific sub-classifications such as L10.0 for Pemphigus vulgaris and L10.1 for Pemphigus vegetans. In the older ICD-9-CM classification system, Pemphigus was primarily coded under 694.4.

What exactly is Pemphigus and how is it classified?

Pemphigus is a rare group of autoimmune blistering diseases that affect the skin and mucous membranes. In these conditions, the body’s immune system mistakenly attacks proteins that act as "glue" between skin cells, leading to the formation of painful blisters. Because Pemphigus encompasses several variants, medical coding is essential for tracking the specific type of disease a patient is experiencing. The ICD-10-CM coding system provides the standardized language used by clinicians, insurance providers, and researchers to document these diagnoses accurately.

How are the ICD-10 and ICD-9 codes used for Pemphigus?

Medical coding for Pemphigus is critical for ensuring that patients receive appropriate insurance coverage and that clinical data is tracked correctly across global health systems. While ICD-9 is largely retired in the United States, it remains a historical reference for older medical records. The transition to ICD-10 allowed for much greater specificity in diagnosing various forms of Pemphigus. The following list outlines the most common ICD-10 codes associated with the clinical presentation of this condition:

• L10.0: Pemphigus vulgaris (the most common form)


• L10.1: Pemphigus vegetans


• L10.2: Pemphigus foliaceus


• L10.3: Brazilian pemphigus (fogo selvagem)


• L10.4: Pemphigus erythematosus


• L10.8: Other pemphigus


• L10.9: Pemphigus, unspecified

Why is accurate coding important for Pemphigus patients?

For the 199 members of the Pemphigus community on DiseaseMaps.org, understanding these codes can be helpful when navigating the healthcare system. Accurate diagnostic coding is not just a bureaucratic necessity; it ensures that your electronic health record reflects the severity and specific subtype of your Pemphigus. This is particularly important for patients seeking specialized treatments, such as rituximab or other immunosuppressive therapies, which often require prior authorization based on specific ICD-10 documentation.

How does the diagnosis of Pemphigus impact daily life?

Receiving a diagnosis of Pemphigus can be emotionally overwhelming, as the condition often requires long-term management and frequent interaction with dermatologists and immunologists. Beyond the medical codes, patients frequently deal with chronic pain and the stress of managing a rare disease. Connecting with others who share this journey can provide much-needed validation and practical tips for managing symptom flares. Remember that while the ICD-10 code defines the disease clinically, your experience as an individual is unique and deserves comprehensive, compassionate care.

Next steps

• Consult a board-certified dermatologist or immunologist to confirm your specific subtype of Pemphigus.


• Check your medical records to ensure your diagnosis is coded correctly, which can assist in insurance approvals for necessary medications.


• Join the active Pemphigus community on DiseaseMaps.org to share experiences and find emotional support from others navigating the same challenges.
