ICD-10 Code G97.1 – Other reaction to spinal and lumbar puncture (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G97.1 – Other reaction to spinal and lumbar puncture
What it is
G97.1 identifies an adverse reaction or complication linked to spinal or lumbar puncture. Use it when the record describes a post-procedure reaction not better classified elsewhere.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings may include headache or other symptoms occurring after a spinal or lumbar puncture, but the chart must support the specific reaction.
When to use this code
Use this code when the provider documents a reaction after a spinal tap or lumbar puncture and does not name a more specific complication. It may apply to post-procedure symptoms clearly attributed to the puncture. Check documentation for timing and causal wording.
Do not use for
Do not use this code for routine post-procedure discomfort without a documented reaction. Also avoid it when the complication is described by a more specific code or when the puncture is unrelated to the current condition.
Coding tip
Code the documented reaction exactly as stated and confirm it is linked to the spinal or lumbar puncture.
