Clinical Information

• Abdominal Abscess

  an abscess located in the abdominal cavity, i.e., the cavity between the diaphragm above and the pelvis below. (from dorland, 27th ed)

• Abscess

  accumulation of purulent material in tissues, organs, or circumscribed spaces, usually associated with signs of infection.

• Amebiasis

  infection with any of various amebae. it is an asymptomatic carrier state in most individuals, but diseases ranging from chronic, mild diarrhea to fulminant dysentery may occur.

• Brain Abscess

  a circumscribed collection of purulent exudate in the brain, due to bacterial and other infections. the majority are caused by spread of infected material from a focus of suppuration elsewhere in the body, notably the paranasal sinuses, middle ear (see ear, middle); heart (see also endocarditis, bacterial), and lung. penetrating craniocerebral trauma and neurosurgical procedures may also be associated with this condition. clinical manifestations include headache; seizures; focal neurologic deficits; and alterations of consciousness. (adams et al., principles of neurology, 6th ed, pp712-6)

• Empyema, Subdural

  an intracranial or rarely intraspinal suppurative process invading the space between the inner surface of the dura mater and the outer surface of the arachnoid.

• Epidural Abscess

  circumscribed collections of suppurative material occurring in the spinal or intracranial epidural space. the majority of epidural abscesses occur in the spinal canal and are associated with osteomyelitis of a vertebral body; analgesia, epidural; and other conditions. clinical manifestations include local and radicular pain, weakness, sensory loss, urinary incontinence, and fecal incontinence. cranial epidural abscesses are usually associated with osteomyelitis of a cranial bone, sinusitis, or otitis media. (from adams et al., principles of neurology, 6th ed, p710 and pp1240-1; j neurol neurosurg psychiatry 1998 aug;65(2):209-12)

• Liver Abscess

  solitary or multiple collections of pus within the liver as a result of infection by bacteria, protozoa, or other agents.

• Liver Abscess, Amebic

  single or multiple areas of pus due to infection by any ameboid protozoa (amebiasis). a common form is caused by the ingestion of entamoeba histolytica.

• Liver Abscess, Pyogenic

  single or multiple areas of pus due to bacterial infection within the hepatic parenchyma. it can be caused by a variety of bacteria, local or disseminated from infections elsewhere such as in appendicitis; cholecystitis; peritonitis; and after liver transplantation.

• Lung Abscess

  solitary or multiple collections of pus within the lung parenchyma as a result of infection by bacteria, protozoa, or other agents.

• Periapical Abscess

  acute or chronic inflammation of tissues surrounding the apical portion of a tooth, associated with the collection of pus, resulting from infection following pulp infection through a carious lesion or as a result of an injury causing pulp necrosis. (dorland, 27th ed)

• Periodontal Abscess

  localized circumscribed purulent area of inflammation in the periodontal tissue. it is a derivative of marginal periodontitis and commonly associated with suprabony and infrabony pockets and interradicular involvements, in contrast to periapical abscess which is attributable to pulp necrosis.

• Peritonsillar Abscess

  an accumulation of purulent material in the area between the palatine tonsil and its capsule.

• Psoas Abscess

  abscess of the psoas muscles resulting usually from disease of the lumbar vertebrae, with the pus descending into the muscle sheath. the infection is most commonly tuberculous or staphylococcal.

• Retropharyngeal Abscess

  an accumulation of purulent material in the space between the pharynx and the cervical vertebrae. this usually results from suppuration of retropharyngeal lymph nodes in patients with upper respiratory tract infections, perforation of the pharynx, or head and neck injuries.

• Subphrenic Abscess

  accumulation of purulent exudates beneath the diaphragm, also known as upper abdominal abscess. it is usually associated with peritonitis or postoperative infections.

• Tuberculoma, Intracranial

  a well-circumscribed mass composed of tuberculous granulation tissue that may occur in the cerebral hemispheres, cerebellum, brain stem, or perimeningeal spaces. multiple lesions are quite common. management of intracranial manifestations vary with lesion site. intracranial tuberculomas may be associated with seizures, focal neurologic deficits, and intracranial hypertension. spinal cord tuberculomas may be associated with localized or radicular pain, weakness, sensory loss, and incontinence. tuberculomas may arise as opportunistic infections, but also occur in immunocompetent individuals.

• Palatine Tonsil

  a round-to-oval mass of lymphoid tissue embedded in the lateral wall of the pharynx. there is one on each side of the oropharynx in the fauces between the anterior and posterior pillars of the soft palate.

• Psoas Muscles

  a powerful flexor of the thigh at the hip joint (psoas major) and a weak flexor of the trunk and lumbar spinal column (psoas minor). psoas is derived from the greek "psoa", the plural meaning "muscles of the loin". it is a common site of infection manifesting as abscess (psoas abscess). the psoas muscles and their fibers are also used frequently in experiments in muscle physiology.

L02.91 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.

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.

Convert L02.91 to ICD-9-CM

• ICD-9-CM Code: 682.9 - Cellulitis NOS
  Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education

Abscess

An abscess is a pocket of pus. You can get an abscess almost anywhere in your body. When an area of your body becomes infected, your body's immune system tries to fight the infection. White blood cells go to the infected area, collect within the damaged tissue, and cause inflammation. During this process, pus forms. Pus is a mixture of living and dead white blood cells, germs, and dead tissue.

Bacteria, viruses, parasites and swallowed objects can all lead to abscesses. Skin abscesses are easy to detect. They are red, raised and painful. Abscesses inside your body may not be obvious and can damage organs, including the brain, lungs and others. Treatments include drainage and antibiotics.
