ICD10 code of Hidradenitis Suppurativa and ICD9 code

Hidradenitis suppurativa, also known as acne inversa, is primarily classified under the ICD-10-CM code L73.2. In the older ICD-9-CM classification system, the condition was identified by the code 705.83.

What is the clinical definition of Hidradenitis Suppurativa?

Hidradenitis suppurativa is a chronic, inflammatory, and debilitating skin condition characterized by the formation of recurrent, painful nodules, abscesses, and sinus tracts in areas where apocrine sweat glands are concentrated. Common sites for these lesions include the axillae (armpits), groin, perianal, and inframammary regions. As the disease progresses, the inflammation leads to tissue destruction, malodorous discharge, and significant scarring. Because Hidradenitis suppurativa is systemic, it involves complex interactions within the immune system and can significantly impact the patient's quality of life.

How is Hidradenitis Suppurativa categorized in medical coding?

Medical coding is essential for billing, tracking patient outcomes, and clinical research. The transition from ICD-9 to ICD-10 provided more specificity for dermatological conditions. When documenting a visit for Hidradenitis suppurativa, clinicians utilize the following:

• ICD-10-CM Code L73.2: This is the current standard code for Hidradenitis suppurativa, covering the inflammatory nature of the disease.


• ICD-9-CM Code 705.83: This historical code was used for Hidradenitis suppurativa prior to the implementation of ICD-10 in October 2015.


• Severity Coding: Clinicians may also use supplementary codes to indicate the presence of secondary infections (such as staph or MRSA) or complications like cellulitis that frequently accompany severe cases of Hidradenitis suppurativa.

What are the implications of a Hidradenitis Suppurativa diagnosis?

Receiving a diagnosis of Hidradenitis suppurativa can be overwhelming, especially given the chronic nature of the condition. With 729 members currently in the DiseaseMaps community sharing their experiences, it is clear that many patients struggle with both the physical pain of abscesses and the emotional burden of the disease. Beyond the skin, Hidradenitis suppurativa can affect the skeletal, reproductive, and endocrine systems, necessitating a multidisciplinary approach to care. Early intervention is critical to prevent the progression of deep-seated scarring and to mitigate the risks of long-term complications like squamous cell carcinoma.

How is this condition managed today?

Management of Hidradenitis suppurativa requires a personalized treatment plan that may include:

1. Topical and systemic antibiotics: Often used to reduce inflammation and control secondary bacterial infections.


2. Biologic therapies: Medications such as adalimumab (Humira) are FDA-approved for moderate to severe Hidradenitis suppurativa to modulate the immune response.


3. Surgical intervention: Ranging from incision and drainage of acute abscesses to wide excision of chronic, scarred tissue.


4. Anti-inflammatory management: Controlling the systemic inflammation associated with the disease to prevent further tissue damage.
