Clinical Information

• Cellulitis-. an acute, diffuse, and suppurative inflammation of loose connective tissue, particularly the deep subcutaneous tissues, and sometimes muscle, which is most commonly seen as a result of infection of a wound, ulcer, or other skin lesions.
• Orbital Cellulitis-. inflammation of the loose connective tissues around the orbit, bony structure around the eyeball. it is characterized by pain; edema of the conjunctiva; swelling of the eyelids; exophthalmos; limited eye movement; and loss of vision.
• Parametritis-. inflammation of the parametrium, the connective tissue of the pelvic floor, extending from the subserous coat of the uterus laterally between the layers of the broad ligament.
• Paronychia-. an inflammatory reaction involving the folds of the skin surrounding the fingernail. it is characterized by acute or chronic purulent, tender, and painful swellings of the tissues around the nail, caused by an abscess of the nail fold. the pathogenic yeast causing paronychia is most frequently candida albicans. saprophytic fungi may also be involved. the causative bacteria are usually staphylococcus, pseudomonas aeruginosa, or streptococcus. (andrews' diseases of the skin, 8th ed, p271)
• Broad Ligament-. a broad fold of peritoneum that extends from the side of the uterus to the wall of the pelvis.
• Grade 1 Paronychia, CTCAE|Grade 1 Paronychia-. nail fold edema or erythema; disruption of the cuticle
• Grade 2 Paronychia, CTCAE|Grade 2 Paronychia-. local intervention indicated; oral intervention indicated (e.g., antibiotic, antifungal, antiviral); nail fold edema or erythema with pain; associated with discharge or nail plate separation; limiting instrumental adl
• Grade 3 Paronychia, CTCAE|Grade 3 Paronychia-. operative intervention indicated; iv antibiotics indicated; limiting self care adl
• Paronychia-. an acute or chronic infection of the soft tissues around the nail. symptoms include pain, tenderness, erythema, and swelling around the nail. acute infection results from minor trauma to the fingertip and staphylococcus aureus is usually the causative agent. chronic infection is usually caused by candida albicans.
• Paronychia, CTCAE|Paronychia|Paronychia-. a disorder characterized by an infectious process involving the soft tissues around the nail.
• Paronychial Inflammation-. swelling and redness of the nail folds.

Diagnostic Related Groups - MS-DRG Mapping

The is diagnosis code is grouped in the following groups for version MS-DRG V40.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2022 through 09/30/2023.

Patient Education

Cellulitis

Cellulitis is an infection of the skin and deep underlying tissues. Group A strep (streptococcal) bacteria are the most common cause. The bacteria enter your body when you get an injury such as a bruise, burn, surgical cut, or wound.

Symptoms include:

• Fever and chills
• Swollen glands or lymph nodes
• A rash with painful, red, tender skin. The skin may blister and scab over.

Your health care provider may take a sample or culture from your skin or do a blood test to identify the bacteria causing infection. Treatment is with antibiotics. They may be oral in mild cases, or intravenous (by IV) for more severe cases.

Lymphatic Diseases

The lymphatic system is a network of tissues and organs. It is made up of:

• Lymph - a fluid that contains white blood cells that defend against germs
• Lymph vessels - vessels that carry lymph throughout your body. They are different from blood vessels.
• Lymph nodes - glands found throughout the lymph vessels. Along with your spleen, these nodes are where white blood cells fight infection.

Your bone marrow and thymus produce the cells in lymph. They are part of the system, too.

The lymphatic system clears away infection and keeps your body fluids in balance. If it's not working properly, fluid builds in your tissues and causes swelling, called lymphedema. Other lymphatic system problems can include infections, blockage, and cancer.
