T85.121 — Displacement of implanted electronic neurostimulator of peripheral nerve electrode (lead)

Not billable

Is T85.121 billable?

No — T85.121 is a non-billable header code. T85.121 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 3 billable codes beneath T85.121.

How is T85.121 listed in the Alphabetic Index?

These are the routes through the Alphabetic Index that lead to T85.121. They show the wording a clinician may have documented, which often differs from the Tabular description.

  • Complication › electronic stimulator device › peripheral nerve › mechanical › displacement (s) (from) (of)
  • Complication › electronic stimulator device › peripheral nerve › mechanical › malposition (s) (from) (of)

Inclusion terms

Alternative wording in documentation that is classified to T85.121.

  • Displacement of electrode (lead) for cranial nerve neurostimulators
  • Displacement of electrode (lead) for gastric neurostimulator
  • Displacement of electrode (lead) for sacral nerve neurostimulator
  • Displacement of electrode (lead) for vagal nerve neurostimulators

Use additional code — inherited from Chapter 19

Report an additional code alongside T85.121 to fully describe the condition. T85.121 is sequenced first.

  • code to identify any retained foreign body, if applicable (Z18.-)

Use additional code — inherited from T80-T88

Report an additional code alongside T85.121 to fully describe the condition. T85.121 is sequenced first.

  • code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5)
  • code(s) to identify the specified condition resulting from the complication
  • code to identify devices involved and details of circumstances (Y62-Y82)

Excludes2 — not included here — inherited from Chapter 19
