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.

What is the ICD-10 code for other disorders of phosphorus metabolism?
The ICD-10-CM code for other disorders of phosphorus metabolism is E83.39 (sometimes written as E8339). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is E83.39 (Disorders of phosphorus metabolism and phosphatases) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report other disorders of phosphorus metabolism on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does E83.39 group to?
When other disorders of phosphorus metabolism is the principal diagnosis on an inpatient stay, it groups to MS-DRG 642 (inborn and Other Disorders of Metabolism), which carries a relative weight of 1.3226. Higher weights mean higher Medicare reimbursement.
Can E83.39 be reported with a code from M83?
Not as a rule. The Excludes1 note at E83.3, which applies to E83.39, lists "adult osteomalacia (M83.-)". 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 E83.39?
Under the General Equivalence Mappings, other disorders of phosphorus metabolism converts to ICD-9-CM 275.3 (dis phosphorus metabol). The mapping is approximate, so confirm the match fits the documentation.
Does E83.39 risk-adjust for Medicare Advantage payment?
Not for Medicare Advantage: E83.39 maps to no category in the CMS-HCC V28 model. It still risk-adjusts in the RxHCC Part D (V08) category 43 (Pituitary, Adrenal Gland, and Other Endocrine and Metabolic Disorders).
