T82.4 — Mechanical complication of vascular dialysis catheter
T82.4 is a non-billable header ICD-10-CM code for mechanical complication of vascular dialysis 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 T82
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
- mechanical complication of intraperitoneal dialysis catheter (T85.62)
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Mechanical complication of hemodialysis catheter
Other codes that can never be billed with T82.4
These codes carry an Excludes1 note pointing at T82.4. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading T82.4 alone.

Risk adjustment
T82.4 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.
Code to one of these instead T82.4
4 child codes. Green means billable.

Questions about T82.4
- Is T82.4 a billable ICD-10-CM code?
- No. T82.4 is a non-billable header code. Code to a higher level of specificity using one of its child codes.
- Where does T82.4 sit in the tabular list?
- Injury, poisoning and certain other consequences of external causes (S00-T88), in the block Complications of surgical and medical care, not elsewhere classified (T80-T88).
- What cannot be coded together with T82.4?
- T82.4 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.
