2025 ICD-10-CM code G31.1
(Active) Effective Date: N/A Diseases of the nervous system - Other degenerative diseases of the nervous system 6 Feed
Senile degeneration of brain, not elsewhere classified.
Medical necessity for services related to this diagnosis should be supported by documentation of the patient's functional impairments, cognitive deficits, and impact on their ability to perform daily activities. Justification for treatments and interventions should be clearly documented.
Symptoms may include loss of cognitive function, memory problems (dementia), sudden confusion (delirium), and behavioral issues. Diagnosis is based on medical history, symptoms, physical and neurological examination, and ruling out other conditions. Blood and urine tests, MRI, or CT scan may be ordered. Treatment may include mental and physical exercises.
In simple words: Senile dementia is a condition characterized by memory loss and changes in personality, behavior, and communication skills in older adults.
This code represents a diagnosis of senile degeneration of the brain that is not classified elsewhere. It is characterized by memory loss and changes in personality, behavior, and communication skills occurring in the elderly.
Example 1: An 80-year-old patient presents with progressive memory loss, difficulty with daily tasks, and personality changes. After ruling out other causes, the physician diagnoses senile degeneration of the brain., A 75-year-old patient exhibits sudden confusion, disorientation, and agitation. The physician diagnoses senile degeneration of the brain after conducting a thorough evaluation and eliminating other potential causes., A 90-year-old patient experiences gradual decline in cognitive function, including language impairment and difficulty with problem-solving. The physician diagnoses senile degeneration of the brain based on the patient's symptoms and clinical findings.
Documentation should include medical history, signs and symptoms, results of physical and neurological examinations, and any diagnostic tests performed (e.g., blood tests, MRI, CT scan). The documentation should also clearly indicate the basis for the diagnosis and how other conditions were ruled out. Specific details regarding the type of dementia observed should also be documented.
** Excludes1: Alzheimer's disease (G30.-) senility NOS (R41.81); Excludes2: certain conditions originating in the perinatal period (P04-P96), certain infectious and parasitic diseases (A00-B99), complications of pregnancy, childbirth, and the puerperium (O00-O9A), congenital malformations, deformations, and chromosomal abnormalities (Q00-Q99), endocrine, nutritional and metabolic diseases (E00-E88), injury, poisoning and certain other consequences of external causes (S00-T88), neoplasms (C00-D49), symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94). Use additional code, if applicable, for codes G31.0-G31.83, G31.85-G31.9, to identify: dementia with anxiety (F02.84, F02.A4, F02.B4, F02.C4) dementia with behavioral disturbance (F02.81-, F02.A1-, F02.B1-, F02.C1-) dementia with mood disturbance (F02.83, F02.A3, F02.B3, F02.C3) dementia with psychotic disturbance (F02.82, F02.A2, F02.B2, F02.C2) dementia without behavioral disturbance (F02.80, F02.A0, F02.B0, F02.C0) mild neurocognitive disorder due to known physiological condition (F06.7-)
