Clinical InformationClinical

  • Lymphocele

    cystic mass containing lymph from diseased lymphatic channels or following surgical trauma or other injury.

  • Cardiac Tamponade

    compression of the heart by accumulated fluid (pericardial effusion) or blood (hemopericardium) in the pericardium surrounding the heart. the affected cardiac functions and cardiac output can range from minimal to total hemodynamic collapse.

  • Thrombocythemia, Essential

    a clinical syndrome characterized by repeated spontaneous hemorrhages and a remarkable increase in the number of circulating platelets.

  • Thrombocytosis

    increased numbers of platelets in the peripheral blood. (dorland, 27th ed)

  • Pulmonary Vein Stenosis

    obstruction of the pulmonary vein in one or multiple sites. the obstruction is the result of wall thickening and narrowing of the lumen of the vein.

  • Inferior Vena Cava Stenosis

    abnormal narrowing of the lumen of the inferior vena cava.

  • Superior Vena Cava Stenosis

    abnormal narrowing of the lumen of the superior vena cava.

  • Grade 1 Lymphocele, CTCAE|Grade 1 Lymphocele|Grade 1 Lymphocele

    asymptomatic; clinical or diagnostic observations only; intervention not indicated

  • Grade 2 Lymphocele, CTCAE|Grade 2 Lymphocele|Grade 2 Lymphocele

    symptomatic; medical intervention indicated

  • Grade 3 Lymphocele, CTCAE|Grade 3 Lymphocele|Grade 3 Lymphocele

    severe symptoms; invasive intervention indicated

  • Lymphocele

    a cystic lesion containing lymph. it usually results from injury, gynecologic surgery, or urologic surgery.

  • Lymphocele, CTCAE|Lymphocele|Lymphocele|Lymphocele

    a disorder characterized by a cystic lesion containing lymph.

  • Microsphere-Mediated Lymphocele Prevention

    a surgical technique that uses microspheres at the site of a lymph node resection in an effort to prevent the formation of a lymphocele.

  • Renal Lymphocele|Kidney Lymphocele|Kidney Lymphocele

    encapsulated collection of lymphatic fluid around a transplanted kidney.

  • Left Ventricular Aneurysm

    a bulge or ballooning in the wall of the left ventricle of the heart.

Questions About I97.89Overview

Is I97.89 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report other postprocedural complications and disorders of the circulatory system, not elsewhere classified on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What MS-DRG does I97.89 group to?

When other postprocedural complications and disorders of the circulatory system, not elsewhere classified is the principal diagnosis on an inpatient stay, it groups to MS-DRG 314, 315, 316, with relative weights from 0.6821 to 2.0852 depending on complications. Higher weights mean higher Medicare reimbursement.

What is the ICD-9 equivalent of I97.89?

Under the General Equivalence Mappings, other postprocedural complications and disorders of the circulatory system, not elsewhere classified converts to ICD-9-CM 997.1 (surg compl-heart) and 997.99 (surg compl-body syst NEC). The mapping is approximate, so confirm the match fits the documentation.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
