T85.121 — Displacement of implanted electronic neurostimulator of peripheral nerve electrode (lead)
T85.121 is a non-billable header ICD-10-CM code for displacement of implanted electronic neurostimulator of peripheral nerve electrode (lead). It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.
This code requires a 7th character
The appropriate 7th character is to be added to each code from category T85
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- 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
Risk adjustment
T85.121 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
How T85.121 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to T85.121.
