Clinical InformationClinical

  • Carotid Body Tumor

    benign paraganglioma at the bifurcation of the common carotid arteries. it can encroach on the parapharyngeal space and produce dysphagia, pain, and cranial nerve palsies.
  • Glomus Jugulare Tumor

    a paraganglioma involving the glomus jugulare, a microscopic collection of chemoreceptor tissue in the adventitia of the bulb of the jugular vein. it may cause paralysis of the vocal cords, attacks of dizziness, blackouts, and nystagmus. it is not resectable but radiation therapy is effective. it regresses slowly, but permanent control is regularly achieved. (from dorland, 27th ed; stedman, 25th ed; devita jr et al., cancer: principles & practice of oncology, 3d ed, pp1603-4)
  • Paraganglioma

    a neural crest tumor usually derived from the chromoreceptor tissue of a paraganglion, such as the carotid body, or medulla of the adrenal gland (usually called a chromaffinoma or pheochromocytoma). it is more common in women than in men. (stedman, 25th ed; from segen, dictionary of modern medicine, 1992)
  • Paraganglioma, Extra-Adrenal

    a relatively rare, usually benign neoplasm originating in the chemoreceptor tissue of the carotid body; glomus jugulare; glomus tympanicum; aortic bodies; and the female genital tract. it consists histologically of rounded or ovoid hyperchromatic cells that tend to be grouped in an alveolus-like pattern within a scant to moderate amount of fibrous stroma and a few large thin-walled vascular channels. (from stedman, 27th ed)
  • Carotid Artery, Common

    the two principal arteries supplying the structures of the head and neck. they ascend in the neck, one on each side, and at the level of the upper border of the thyroid cartilage, each divides into two branches, the external (carotid artery, external) and internal (carotid artery, internal) carotid arteries.
  • Secondary Polycythemia

    polycythemia resulting from an elevated concentration of erythropoietin.
  • Erythrocytosis

    abnormally high level of red blood cells in the blood.
  • Familial Polycythemia|Familial Erythrocytosis

    polycythemia that occurs in groups of related individuals.
  • Stress Polycythemia

    polycythemia that is caused by stress.
  • TEMPI Syndrome

    a rare syndrome characterized by telangiectasias, elevated erythropoietin level and erythrocytosis, monoclonal gammopathy, perinephric fluid collections, and intrapulmonary shunting. it is best classified as a type of plasma cell dyscrasia with paraneoplastic manifestations.

Patient EducationClinical

Blood Disorders

Your blood is living tissue made up of liquid and solids. The liquid part, called plasma, is made of water, salts and protein. Over half of your blood is plasma. The solid part of your blood contains red blood cells, white blood cells and platelets.

Questions About D75.1Overview

Is D75.1 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report secondary polycythemia on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What MS-DRG does D75.1 group to?

When secondary polycythemia is the principal diagnosis on an inpatient stay, it groups to MS-DRG 814, 815, 816, with relative weights from 0.6320 to 2.1267 depending on complications. Higher weights mean higher Medicare reimbursement.

What is the ICD-9 equivalent of D75.1?

Under the General Equivalence Mappings, secondary polycythemia converts to ICD-9-CM 289.0 (secondary polycythemia). The mapping is a direct match.

Footnotes

[1] Chronic - a chronic condition code indicates a condition lasting 12 months or longer and its effect on the patient based on one or both of the following criteria:

  • The condition results in the need for ongoing intervention with medical products,treatment, services, and special equipment
  • The condition places limitations on self-care, independent living, and social interactions.
