Clinical Information

• Hidradenitis Suppurativa

  a chronic suppurative and cicatricial disease of the apocrine glands occurring chiefly in the axillae in women and in the groin and anal regions in men. it is characterized by poral occlusion with secondary bacterial infection, evolving into abscesses which eventually rupture. as the disease becomes chronic, ulcers appear, sinus tracts enlarge, fistulas develop, and fibrosis and scarring become evident.

• Hidradenitis

  the inflammation of a sweat gland (usually of the apocrine type). the condition can be idiopathic or occur as a result of or in association with another underlying condition. neutrophilic eccrine hidradenitis is a relatively rare variant that has been reported in patients undergoing chemotherapy, usually for non-hodgkin lymphomas or leukemic conditions.

• Hidradenitis Suppurativa

  a chronic, suppurative inflammation of the apocrine sweat glands, that is characterized by clusters of bumps or sores.

• Neutrophilic Eccrine Hidradenitis

  painful red or pink edematous nodules most commonly found on the palmar and/or plantar regions.

• Hidradenitis

  inflammation of the apocrine sweat glands, characterized by redness, itching, pain or swelling of the sweat glands, usually in the axillae or groin.

• Infectious Hidradenitis

  hidradenitis that is caused by an infectious agent, usually a bacterium.

L73.2 is grouped with Diagnostic Related Groups - MS-DRG Mapping

Diagnostic Related Groups (DRGs) are a classification system used to group together diagnosis codes for the purpose of reimbursement and healthcare management. DRGs are used to standardize the way hospitals and other providers are paid for inpatient services. In this system patients are grouped together based on their principal diagnosis in areas referred to as Major Diagnostic Categories (MDC). Once a patient is assigned a particular diagnostic category, providers receive a predetermined payment rate for the services rendered. This reimbursement rate is often fixed and is meant to cover the cost of care for that patient. Reimbursement is also affected by the relative weight of a diagnostic related group based on the severity of a patient's illness and the associated cost of care during hospitalization.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V41.0 applicable from 10/01/2023 through 09/30/2024.

MS-DRG	MS-DRG Title	MCD	Relative Weight
606	MINOR SKIN DISORDERS WITH MCC	09	1.5858
607	MINOR SKIN DISORDERS WITHOUT MCC	09	0.8935

The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

Patient Education

Hidradenitis Suppurativa

What is hidradenitis suppurativa (HS)?

Hidradenitis suppurativa (HS) is a chronic skin disease. It causes painful, boil-like lumps that form under the skin. It often affects areas where the skin rubs together, such as your armpits and groin. The lumps become inflamed and painful. They often break open, causing abscesses that drain fluid and pus. As the abscesses heal, they can cause scarring of the skin.

What causes hidradenitis suppurativa (HS)?

The lumps in HS form because of blockages of the hair follicles. The blocked hair follicles trap bacteria, which leads to inflammation and rupture. In most cases, the cause of the blockages is unknown. Genetics, environment, and hormonal factors may play a role. Some cases of HS are caused by changes in certain genes.

HS is not caused by bad hygiene, and it cannot be spread to others.

Who is at risk for hidradenitis suppurativa (HS)?

HS usually starts after puberty, usually in the teens or twenties. It is more common in:

• Women
• People with a family history of HS
• People who are overweight or have obesity
• Smokers

What are the symptoms of hidradenitis suppurativa (HS)?

The symptoms of HS include:

• Small pitted areas of skin containing blackheads
• Painful, red, lumps that get bigger and break open. This causes abscesses that drain fluid and pus. They may itch and have an unpleasant odor.
• The abscesses heal very slowly, recur over time, and can lead to scarring and tunnels under the skin

HS can be mild, moderate, or severe:

• In mild HS, there are only one or a few lumps in one area of the skin. A mild case will often get worse, becoming a moderate disease.
• Moderate HS include recurrences of the lumps that get bigger and break open. The lumps form in more than one area of the body.
• With severe HS, there are widespread lumps, scarring, and chronic pain that may make it hard to move

Because of the difficulty of dealing with the disease, people with HS are at risk for depression and anxiety.

How is hidradenitis suppurativa (HS) diagnosed?

There is no specific test for HS, and it is often misdiagnosed in the early stages. To make a diagnosis, your health care provider will ask about your medical history and your symptoms. He or she will look at the lumps on your skin and test a sample of the skin or pus (if there is any).

What are the treatments for hidradenitis suppurativa?

There is no cure for HS. Treatments focus on the symptoms, but they are not always effective for everyone. The treatments depend on how severe the disease is, and they include:

• Medicines, including steroids, antibiotics, pain relievers, and medicines that flight inflammation. In mild cases, the medicines may be topical. This means that you apply them to your skin. Otherwise the medicines may be injected or taken orally (by mouth).
• Surgery for severe cases, to remove the lumps and scars

It may also help if you can avoid things that can irritate your skin, by:

• Wearing loose-fitting clothing
• Staying at a healthy weight
• Quitting smoking
• Avoiding heat and humidity
• Being careful not to injure your skin

Hidradenitis suppurativa

Hidradenitis suppurativa, also known as acne inversa, is a chronic skin disease characterized by recurrent boil-like lumps (nodules) under the skin. The nodules become inflamed and painful. They tend to break open (rupture), causing abscesses that drain fluid and pus. As the abscesses heal, they produce significant scarring of the skin.

The signs and symptoms of hidradenitis suppurativa typically appear after puberty, usually in a person's teens or twenties, although they can begin earlier in puberty, particularly in affected females. Nodules are most likely to form in the armpits and groin. They may also develop around the anus, on the buttocks, or under the breasts. In some cases, nodules appear in other areas, such as the nape of the neck, waist, and inner thighs.

The recurrent nodules and abscesses cause chronic pain and can lead to self-consciousness, social isolation, and depression. Rarely, long-term (chronic) abscesses on the buttocks can develop into a type of skin cancer called squamous cell carcinoma.
