G92.0
Header — not billableImmune effector cell-associated neurotoxicity syndrome
The ICD-10 code for immune effector cell-associated neurotoxicity syndrome is G92.0.
G92.0 is a non-billable header code. It groups related conditions but cannot be used on its own for reimbursement — select one of the 6 more specific codes below.
Clinical notes
Code also
Two codes may be needed to fully describe a condition, but unlike Code First/Use Additional Code, the sequencing order is not mandated by convention.
Code first
This code represents a manifestation of an underlying disease. Coding convention requires the underlying (etiology) code to be sequenced first, with this code listed second.
- underlying cause such as:
- complications of immune effector cellular therapy (T80.82)
Documentation support
General coding-documentation guidance — not a substitute for payer-specific requirements or professional coding judgment.
- •This is a non-billable header code. Documentation must support a more specific child code before this diagnosis can be reported on a claim.
- •This code represents a manifestation. Documentation should identify the underlying condition, which must be coded first.
- •As a general rule, code to the highest level of specificity supported by the documentation in the medical record.
