Frequently Asked Questions (FAQ) & Clinical Guidance
Does T84.021A require a 7th character?
Yes. The appropriate 7th character is to be added to each code from category T84.
Can T84.021A be reported alongside related conditions?
Per official ICD-10-CM Excludes2 instructions, T84.021A 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 tissues (T86.-); fracture of bone following insertion of orthopedic implant, joint prosthesis or bone plate (M96.6); any encounters with medical care for postprocedural conditions in which no complications are present, such as:; artificial opening status (Z93.-).
Is an additional code needed with T84.021A?
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).
