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 cardiac and vascular prosthetic devices, implants and grafts
        (T82)

T82.399D is a billable diagnosis code used to specify a medical diagnosis of other mechanical complication of unspecified vascular 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.

T82.399D 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 unspecified vascular 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.

Unspecified diagnosis codes like T82.399D are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Bypass graft mechanical complications
  • Complication of totally implantable venous access device
  • Mechanical complication of vascular device
  • Mechanical complication of venous catheter
  • Obstruction of totally implantable venous access device
  • Persistent flow of blood into aneurysm sac following endovascular insertion of stent graft
  • Vascular graft occlusion

Clinical Classification

Coding Guidelines

The appropriate 7th character is to be added to each code from block Complications of cardiac and vascular prosthetic devices, implants and grafts (T82). Use the following options for the aplicable episode of care:

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela

Present on Admission (POA)

T82.399D is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here.
