Code Classification

  • Injury, poisoning and certain other consequences of external causes
    (S00–T88)
    • Complications of surgical and medical care, not elsewhere classified
      (T80-T88)
      • Complications of internal orthopedic prosthetic devices, implants and grafts
        (T84)

T84.498D is a billable diagnosis code used to specify a medical diagnosis of other mechanical complication of other internal orthopedic devices, implants and grafts, subsequent encounter. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.

T84.498D is a subsequent encounter code, includes a 7th character and should be used after the patient has completed active treatment for a condition like other mechanical complication of other internal orthopedic devices implants and grafts. According to ICD-10-CM Guidelines a "subsequent encounter" occurs when the patient is receiving routine care for the condition during the healing or recovery phase of treatment. Subsequent diagnosis codes are appropriate during the recovery phase, no matter how many times the patient has seen the provider for this condition. If the provider needs to adjust the patient's care plan due to a setback or other complication, the encounter becomes active again.
