 Other conditions of brain- 348 is a non-specific code that cannot be used to specify a diagnosis
Cerebral cysts- A fluid filled sac within the cerebrum. It is can be congenital, trauma related or secondary to another medical condition for example an infarction.
- 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. Spinal arachnoid cysts may be extradural, intradural, or perineural and tend to present with signs and symptoms indicative of a RADICULOPATHY. (From Joynt, Clinical Neurology, 1994, Ch44, pp105-115)
- 348.0 is a specific code that can be used to specify a diagnosis
- 348.0 contains 18 index entries
Anoxic brain damage- 348.1 is a specific code that can be used to specify a diagnosis
- 348.1 contains 3 index entries
Benign intracranial hypertension- A condition marked by raised intracranial pressure and characterized clinically by HEADACHES; NAUSEA; PAPILLEDEMA, peripheral constriction of the visual fields, transient visual obscurations, and pulsatile TINNITUS. OBESITY is frequently associated with this condition, which primarily affects women between 20 and 44 years of age. Chronic PAPILLEDEMA may lead to optic nerve injury (see OPTIC NERVE DISEASES) and visual loss (see BLINDNESS).
- 348.2 is a specific code that can be used to specify a diagnosis
- 348.2 contains 10 index entries
Encephalopathy, not elsewhere classified- A disorder of the brain that can be caused by disease, injury, drugs, or chemicals.
- 348.3 is a non-specific code that cannot be used to specify a diagnosis
Encephalopathy unspecified- A disorder of the brain that can be caused by disease, injury, drugs, or chemicals.
- 348.30 is a specific code that can be used to specify a diagnosis
- 348.30 contains 3 index entries
Metabolic encephalopathy- Acquired or inborn metabolic diseases that produce brain dysfunction or damage. These include primary (i.e., disorders intrinsic to the brain) and secondary (i.e., extracranial) metabolic conditions that adversely affect cerebral function.
- 348.31 is a specific code that can be used to specify a diagnosis
- 348.31 contains 2 index entries
Other encephalopathy- 348.39 is a specific code that can be used to specify a diagnosis
- 348.39 contains 4 index entries
Compression of brain- 348.4 is a specific code that can be used to specify a diagnosis
- 348.4 contains 14 index entries
Cerebral edema- Increased intracellular or extracellular fluid in brain tissue. Cytotoxic brain edema (swelling due to increased intracellular fluid) is indicative of a disturbance in cell metabolism, and is commonly associated with hypoxic or ischemic injuries (see HYPOXIA, BRAIN). An increase in extracellular fluid may be caused by increased brain capillary permeability (vasogenic edema), an osmotic gradient, local blockages in interstitial fluid pathways, or by obstruction of CSF flow (e.g., obstructive HYDROCEPHALUS). (From Childs Nerv Syst 1992 Sep; 8(6):301-6)
- 348.5 is a specific code that can be used to specify a diagnosis
- 348.5 contains 6 index entries
Other conditions of brain- 348.8 is a specific code that can be used to specify a diagnosis
- 348.8 contains 27 index entries
Unspecified condition of brain- 348.9 is a specific code that can be used to specify a diagnosis
- 348.9 contains 5 index entries
