T82.21 — Mechanical complication of coronary artery bypass graft
Is T82.21 billable?
No — T82.21 is a non-billable header code. T82.21 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 12 billable codes beneath T82.21.

Excludes1 — never code together — inherited from T82.2
The conditions below can never be reported together with T82.21 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- mechanical complication of artificial heart valve prosthesis (T82.0-)
Use additional code — inherited from Chapter 19
Report an additional code alongside T82.21 to fully describe the condition. T82.21 is sequenced first.
- code to identify any retained foreign body, if applicable (Z18.-)
Use additional code — inherited from T80-T88
Report an additional code alongside T82.21 to fully describe the condition. T82.21 is sequenced first.
Excludes2 — not included here — inherited from Chapter 19
The conditions below are not part of T82.21, but a patient may have both at the same time. When documentation supports it, T82.21 and the excluded code may both be reported.
Excludes2 — not included here — inherited from T80-T88
The conditions below are not part of T82.21, but a patient may have both at the same time. When documentation supports it, T82.21 and the excluded code may both be reported.
- any encounters with medical care for postprocedural conditions in which no complications are present, such as:
- artificial opening status (Z93.-)
- closure of external stoma (Z43.-)
- fitting and adjustment of external prosthetic device (Z44.-)
- burns and corrosions from local applications and irradiation (T20-T32)
- complications of surgical procedures during pregnancy, childbirth and the puerperium (O00-O9A)
- mechanical complication of respirator [ventilator] (J95.850)
- poisoning and toxic effects of drugs and chemicals (T36-T65 with fifth or sixth character 1-4 or 6)
- postprocedural fever (R50.82)
- specified complications classified elsewhere, such as:
- cerebrospinal fluid leak from spinal puncture (G97.0)
- colostomy malfunction (K94.0-)
- disorders of fluid and electrolyte imbalance (E86-E87)
- functional disturbances following cardiac surgery (I97.0-I97.1)
- intraoperative and postprocedural complications of specified body systems (D78.-, E36.-, E89.-, G97.3-, G97.4, H59.3-, H59.-, H95.2-, H95.3, I97.4-, I97.5, J95.6-, J95.7, K91.6-, L76.-, M96.-, N99.-)
- ostomy complications (J95.0-, K94.-, N99.5-)
- postgastric surgery syndromes (K91.1)
- postlaminectomy syndrome NEC (M96.1)
- postmastectomy lymphedema syndrome (I97.2)
- postsurgical blind-loop syndrome (K91.2)
- ventilator associated pneumonia (J95.851)
Excludes2 — not included here — inherited from T82
The conditions below are not part of T82.21, but a patient may have both at the same time. When documentation supports it, T82.21 and the excluded code may both be reported.
- failure and rejection of transplanted organs and tissue (T86.-)

How long has T82.21 existed?
T82.21 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
