Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to E83.59: its own notes plus those printed at E83.5, E83, block E70-E88, and Chapter 4. A note printed at a category, block or chapter applies to every code under it.

Notes
General instructions on how these codes are used.
- All neoplasms, whether functionally active or not, are classified in Chapter 2. Appropriate codes in this chapter (i.e. E05.8, E07.0, E16-E31, E34.-) may be used as additional codes to indicate either functional activity by neoplasms and ectopic endocrine tissue or hyperfunction and hypofunction of endocrine glands associated with neoplasms and other conditions classified elsewhere.

Clinical InformationClinical
Calcinosis
pathologic deposition of calcium salts in tissues.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.
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.

The ICD-10-CM code for other disorders of calcium metabolism is E83.59 (sometimes written as E8359). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
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, 2026 through September 30, 2027.
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 641, 640, with relative weights from 0.7864 to 1.3392 depending on complications. Higher weights mean higher Medicare reimbursement.
Can E83.59 be reported with E20.812?
Not as a rule. The Excludes1 note at E83.5, which applies to E83.59, lists "autoimmune hypoparathyroidism (E20.812)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
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.
