Clinical InformationClinical

  • Medullary Sponge Kidney

    a non-hereditary kidney disorder characterized by the abnormally dilated (ectasia) medullary and inner papillary portions of the collecting ducts. these collecting ducts usually contain cysts or diverticula filled with jelly-like material or small calculi (kidney stones) leading to infections or obstruction. it should be distinguished from congenital or hereditary polycystic kidney diseases.

  • Calciphylaxis

    condition of induced systemic hypersensitivity in which tissues respond to appropriate challenging agents with a sudden local calcification.

  • Nephrocalcinosis

    a condition characterized by calcification of the renal tissue itself. it is usually seen in distal renal tubular acidosis with calcium deposition in the distal kidney tubules and the surrounding interstitium. nephrocalcinosis causes renal insufficiency.

  • Calcinosis

    pathologic deposition of calcium salts in tissues.

  • Calcinosis Cutis

    pathological deposition of calcium in the skin and subcutaneous tissue. excessive calcification of the skin may be associated with underlying diseases that cause tissue damage (e.g., ehlers-danlos syndrome; pseudoxanthoma elasticum; rothmund-thomson syndrome; and werner syndrome) or that cause abnormal calcium and phosphate metabolism (e.g., calciphylaxis; chronic kidney failure; hyperparathyroidism; and sarcoidosis).

  • CREST Syndrome

    a mild form of limited scleroderma, a multi-system disorder. its features include symptoms of calcinosis; raynaud disease; esophageal motility disorders; sclerodactyly, and telangiectasis. when the defect in esophageal function is not prominent, it is known as crst syndrome.

  • Vascular Calcification

    deposition of calcium into the blood vessel structures. excessive calcification of the vessels is associated with atherosclerotic plaques formation particularly after myocardial infarction (see monckeberg medial calcific sclerosis) and chronic kidney diseases which in turn increase vascular stiffness.

  • Medullary Sponge Kidney

    a developmental disorder of the kidney characterized by cystic dilatation of the medullary collecting ducts, resulting in a spongy gross appearance of the kidney. it may be asymptomatic or complicated by hematuria, infections, or renal stones.

  • Calciphylaxis

    a rare syndrome characterized by vascular calcification and skin necrosis. it seen in patients with end stage renal disease.

  • Nephrocalcinosis

    deposition of calcium in the renal parenchyma, resulting from high levels of calcium in the blood and/or urine.

Patient EducationClinical

Calcium

Calcium is a mineral, a nutrient that you need (in small amounts) to keep your body healthy. You have more calcium in your body than any other mineral.

Questions About E83.59Overview

Is E83.59 (Disorders of calcium metabolism) a billable code?

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

What MS-DRG does E83.59 group to?

When other disorders of calcium metabolism is the principal diagnosis on an inpatient stay, it groups to MS-DRG 640, 641, with relative weights from 0.7782 to 1.3356 depending on complications. Higher weights mean higher Medicare reimbursement.

What is the ICD-9 equivalent of E83.59?

Under the General Equivalence Mappings, other disorders of calcium metabolism converts to ICD-9-CM 275.49 (dis calcium metablsm NEC). The mapping is approximate, so confirm the match fits the documentation.

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.
