As of October 2015, ICD-9 codes are no longer used for medical coding. Instead, use the following two equivalent ICD-10-CM codes, which are an approximate match to ICD-9 code 345.40:
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
345.40 is a legacy non-billable code used to specify a medical diagnosis of localization-related (focal) (partial) epilepsy and epileptic syndromes with complex partial seizures, without mention of intractable epilepsy. This code was replaced on September 30, 2015 by its ICD-10 equivalent.
The following crosswalk between ICD-9 to ICD-10 is based based on the General Equivalence Mappings (GEMS) information:
Epilepsy is a brain disorder that causes people to have recurring seizures. The seizures happen when clusters of nerve cells, or neurons, in the brain send out the wrong signals. People may have strange sensations and emotions or behave strangely. They may have violent muscle spasms or lose consciousness.
General Equivalence Map Definitions The ICD-9 and ICD-10 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.
As of October 2015, ICD-9 codes are no longer used for medical coding. Instead, use this equivalent ICD-10-CM code, which is an exact match to ICD-9 code 345:
Non-Billable means the code is not sufficient justification for admission to an acute care hospital when used a principal diagnosis. Use a child code to capture more detail.
