T81.33 — Disruption of traumatic injury wound repair
T81.33 is a non-billable header ICD-10-CM code for disruption of traumatic injury wound repair. 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 T81
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Disruption or dehiscence of closure of traumatic laceration (external) (internal)
Excludes1 inherited from the categories above T81.33
These are not written on T81.33, but they bind it: a note on a category applies to every code beneath it. Billing T81.33 with anything listed here is a denial.
Written on T81.3 — Disruption of wound, not elsewhere classified
Excludes2 inherited from the categories above T81.33
Also inherited, and the opposite of Excludes1: these conditions are not part of T81.33, but a patient can have both, so you may code both.
Written on T81 — Complications of procedures, not elsewhere classified
- complications following immunization (T88.0-T88.1)
- complications following infusion, transfusion and therapeutic injection (T80.-)
- complications of transplanted organs and tissue (T86.-)
- specified complications classified elsewhere, such as:
- complication of prosthetic devices, implants and grafts (T82-T85)
- dermatitis due to drugs and medicaments (L23.3, L24.4, L25.1, L27.0-L27.1)
- endosseous dental implant failure (M27.6-)
- floppy iris syndrome (IFIS) (intraoperative) H21.81
- intraoperative and postprocedural complications of specific body system (D78.-, E36.-, E89.-, G97.3-, G97.4, H59.3-, H59.-, H95.2-, H95.3, I97.4-, I97.5, J95, K91.-, L76.-, M96.-, N99.-)
- ostomy complications (J95.0-, K94.-, N99.5-)
- plateau iris syndrome (post-iridectomy) (postprocedural) H21.82
- poisoning and toxic effects of drugs and chemicals (T36-T65 with fifth or sixth character 1-4)
Risk adjustment
T81.33 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 T81.33 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 T81.33.

Questions about T81.33
- Is T81.33 a billable ICD-10-CM code?
- No. T81.33 is a non-billable header code. Code to a higher level of specificity using one of its child codes.
- Where does T81.33 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 T81.33?
- T81.33 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above T81.33 (T81.3) and apply to it just the same.
