T82.2 ICD-10-CM Code: Mechanical complication of coronary artery bypass graft and biological heart valve graft
T82.2 is the authoritative medical code for Mechanical complication of coronary artery bypass graft and biological heart valve graft. This classification is used in medical billing and clinical recording to specify the clinical criteria for mechanical complication of coronary artery bypass graft and biological heart valve graft (ICD-10-CM T82.2), ensuring healthcare documentation aligns with current federal coding standards.
Billing Status: NO. This is a clinician non-billable / parent hierarchy grouping in the ICD-10-CM system.
Code Set: Valid FY2026 and FY2027. FY2026 took effect October 1, 2025.

Use Additional Code
Supplementary codes the tabular list directs you to add.
- Use additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5)
- Use additional code(s) to identify the specified condition resulting from the complication
- Use additional code to identify devices involved and details of circumstances (Y62-Y82)
Frequently Asked Questions (FAQ) & Clinical Guidance
Can T82.2 be billed directly?
No. T82.2 (Mechanical complication of coronary artery bypass graft and biological heart valve graft) is a non-billable ICD-10-CM category code. A more specific billable subcode must be selected based on clinical documentation.
Does T82.2 require a 7th character?
Yes. The appropriate 7th character is to be added to each code from category T82.
What can't be coded together with T82.2?
Per official ICD-10-CM Excludes1 instructions, T82.2 must not be reported together with: mechanical complication of artificial heart valve prosthesis (T82.0-).
Can T82.2 be reported alongside related conditions?
Per official ICD-10-CM Excludes2 instructions, T82.2 and the following are not considered part of each other and may both be reported when both conditions are present: failure and rejection of transplanted organs and tissue (T86.-); 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.-).
Is an additional code needed with T82.2?
Use additional code(s) to specify: code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5); code(s) to identify the specified condition resulting from the complication; code to identify devices involved and details of circumstances (Y62-Y82).
