Clinical Information

• Arachnoid

  a delicate membrane enveloping the brain and spinal cord. it lies between the pia mater and the dura mater. it is separated from the pia mater by the subarachnoid cavity which is filled with cerebrospinal fluid.

• Arachnoid Cysts

  intracranial or spinal cavities containing a cerebrospinal-like fluid, the wall of which is composed of arachnoidal cells. they are most often developmental or related to trauma. intracranial arachnoid cysts usually occur adjacent to arachnoidal cistern and may present with hydrocephalus; headache; seizures; and focal neurologic signs. (from joynt, clinical neurology, 1994, ch44, pp105-115)

• Arachnoiditis

  acute or chronic inflammation of the arachnoid membrane of the meninges most often involving the spinal cord or base of the brain. this term generally refers to a persistent inflammatory process characterized by thickening of the arachnoid membrane and dural adhesions. associated conditions include prior surgery, infections, trauma, subarachnoid hemorrhage, and chemical irritation. clinical features vary with the site of inflammation, but include cranial neuropathies, radiculopathies, and myelopathies. (from joynt, clinical neurology, 1997, ch48, p25)

• Medulloblastoma

  a malignant neoplasm that may be classified either as a glioma or as a primitive neuroectodermal tumor of childhood (see neuroectodermal tumor, primitive). the tumor occurs most frequently in the first decade of life with the most typical location being the cerebellar vermis. histologic features include a high degree of cellularity, frequent mitotic figures, and a tendency for the cells to organize into sheets or form rosettes. medulloblastoma have a high propensity to spread throughout the craniospinal intradural axis. (from devita et al., cancer: principles and practice of oncology, 5th ed, pp2060-1)

• Cauda Equina

  the lower part of the spinal cord consisting of the lumbar, sacral, and coccygeal nerve roots.

• Cauda Equina Syndrome

  compressive lesion affecting the nerve roots of the cauda equina (e.g., compression, herniation, inflammation, rupture, or stenosis), which controls the function of the bladder and bowel. symptoms may include neurological dysfunction of bladder or bowels, loss of sexual sensation and altered sensation or paralysis in the lower extremities.

• Meninges

  the three membranes that cover the brain and the spinal cord. they are the dura mater, the arachnoid, and the pia mater.

• Meningocele

  a congenital or acquired protrusion of the meninges, unaccompanied by neural tissue, through a bony defect in the skull or vertebral column.

• Pia Mater

  the innermost layer of the three meninges covering the brain and spinal cord. it is the fine vascular membrane that lies under the arachnoid and the dura mater.

• Empty Sella Syndrome

  a condition when the sella turcica is not filled with pituitary tissue. the pituitary gland is either compressed, atrophied, or removed. there are two types: (1) primary empty sella is due a defect in the sella diaphragm leading to arachnoid herniation into the sellar space; (2) secondary empty sella is associated with the removal or treatment of pituitary neoplasms.

• Sella Turcica

  a bony prominence situated on the upper surface of the body of the sphenoid bone. it houses the pituitary gland.

• Cerebrospinal Fluid Rhinorrhea

  discharge of cerebrospinal fluid through the nose. common etiologies include trauma, neoplasms, and prior surgery, although the condition may occur spontaneously. (otolaryngol head neck surg 1997 apr;116(4):442-9)

• Cerebrospinal Fluid Rhinorrhea

  discharge of cerebrospinal fluid through the nose.

D49.7 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.

Table of Neoplasms

This code is referenced in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.

Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.
