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 Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter.

T82.4

T82.4 — Mechanical complication of vascular dialysis catheter

Non-billable headerICD-10-CM

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

Excludes2 inherited from the categories above T82.4

Also inherited, and the opposite of Excludes1: these conditions are not part of T82.4, but a patient can have both, so you may code both.

Written on T82 — Complications of cardiac and vascular prosthetic devices, implants and grafts

failure and rejection of transplanted organs and tissue (T86.-)

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 history

T82.4 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
