ICD-10 Code I69.934 – Monoplegia of Upper Limb Following Unspecified Cerebrovascular Disease Affecting Left Non-Dominant Side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.934 – Monoplegia of upper limb following unspecified cerebrovascular disease affecting left non-dominant side
What it is
This code identifies paralysis affecting one upper limb after an unspecified cerebrovascular disease, with the left side documented as non-dominant. It is a sequela code, so the weakness or loss of movement remains after the original stroke-related event.
Clinical signs
You may see persistent loss of voluntary movement, marked weakness, or limited function in the left upper extremity. Clinical features vary; refer to documentation for laterality, dominance, and whether the deficit is residual from a prior cerebrovascular event.
When to use this code
Use this code when the record clearly states monoplegia of the upper limb as a residual effect of an unspecified cerebrovascular disease. It fits follow-up encounters where the acute stroke phase is no longer the focus and the left non-dominant arm deficit is documented. Confirm that the provider links the paralysis to the prior cerebrovascular condition.
Do not use for
Do not use it for acute stroke, transient symptoms, or paralysis from non-cerebrovascular causes. Check documentation if the side, dominance, or relationship to the prior event is unclear.
Coding tip
Code the residual deficit only when the sequela relationship is documented and the left non-dominant side is specified.
