The more specific codes under it are T84.81 Embolism due to internal orthopedic prosthetic devices, implants and grafts; T84.82 Fibrosis due to internal orthopedic prosthetic devices, implants and grafts; T84.83 Hemorrhage due to internal orthopedic prosthetic devices, implants and grafts; T84.84 Pain due to internal orthopedic prosthetic devices, implants and grafts and 3 more. Its coding notes include a Use additional code instruction and 25 Excludes2 entries.

Every code below needs one of these (defined at T84).

The appropriate 7th character is to be added to each code from category T84

Guidelines tips

From the FY2027 Official Guidelines. ICD10Ref adds no rules of its own.

The 7th character depends on whether the patient is in active treatment, not on who sees the patient. An aftercare Z code is not used for injury aftercare.

Guidelines I.C.19.aInjuries: application of 7th charactersRead the official text

A complication code needs the provider's documented cause-and-effect link between the care and the condition. Some T codes already include the type of procedure, so no external cause code is needed.

Use additional code

Add the listed code as a secondary code, if known.

Notes

Also from chapter/block level (2 notes)

Inherited from Chapter 19 Injury, poisoning and certain other consequences of external causes

Use secondary code(s) from Chapter 20, External causes of morbidity, to indicate cause of injury. Codes within the T section that include the external cause do not require an additional external cause code
The chapter uses the S-section for coding different types of injuries related to single body regions and the T-section to cover injuries to unspecified body regions as well as poisoning and certain other consequences of external causes.
