2025 ICD-10-CM code Z98.2
Presence of cerebrospinal fluid (CSF) drainage device (shunt).
Medical necessity for services related to the CSF drainage device must be supported by documentation justifying the need for the encounter.For example, if the encounter is for shunt malfunction, documentation should describe the signs and symptoms supporting the diagnosis.
Clinicians use this code to document the continued presence of a CSF drainage device, often to explain current symptoms or guide future treatment. The responsible clinician is typically a neurosurgeon or other specialist who manages CSF shunts.
In simple words: This code indicates that the patient has a shunt, a tube-like device used to drain excess fluid from the brain and spinal cord.
This code indicates the presence of a cerebrospinal fluid drainage device, such as a shunt, typically placed surgically to divert excess CSF.It is used to document the status of a patient who has undergone such a procedure.
Example 1: A patient presents for a follow-up appointment after placement of a ventriculoperitoneal (VP) shunt to treat hydrocephalus. The Z98.2 code is used to document the presence of the shunt., A patient with a pre-existing VP shunt experiences headaches. The Z98.2 code is used to document the shunt's presence as part of the evaluation for the headache's cause., A patient with a history of a lumboperitoneal (LP) shunt presents for an unrelated medical issue. The Z98.2 code is used to document the presence of the shunt as part of the patient's medical history.
Documentation should include details about the type of CSF drainage device (e.g., VP shunt, LP shunt), the date of the original shunt placement procedure, and the reason for the current encounter. Any complications related to the shunt should be coded separately.
** This code is used to indicate the presence of the device, not the reason for its placement. The underlying condition that necessitated the shunt placement should be coded separately if it is relevant to the current encounter.
