T85.735 — Infection and inflammatory reaction due to cranial or spinal infusion catheter
T85.735 is a non-billable header ICD-10-CM code for infection and inflammatory reaction due to cranial or spinal infusion catheter. 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.
- Infection and inflammatory reaction due to epidural catheter
- Infection and inflammatory reaction due to intrathecal infusion catheter
- Infection and inflammatory reaction due to subarachnoid catheter
- Infection and inflammatory reaction due to subdural catheter
Risk adjustment
T85.735 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 T85.735 is indexed
