ICD-10-CM M83.0
CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

M83.0 is a billable ICD-10-CM diagnosis code for puerperal osteomalacia. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 553 through 554. The code is restricted by the Medicare Code Editor to maternity cases (age 9 through 64). Coders also document this condition as bone AND/OR joint disorder in mother complicating pregnancy, childbirth AND/OR puerperium. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Complications specified during the puerperium, Osteomalacia, and Other specified bone disease and musculoskeletal deformities.

M83.0 does not risk-adjust for Medicare Advantage under the CMS-HCC V28 model. It still risk-adjusts in the RxHCC Part D (V08) category 87 for payment year 2027.

Bone Diseases

Your bones help you move, give you shape and support your body. They are living tissues that rebuild constantly throughout your life. During childhood and your teens, your body adds new bone faster than it removes old bone. After about age 20, you can lose bone faster than you make bone.

Questions About M83.0Overview

What is the ICD-10 code for puerperal osteomalacia?

The ICD-10-CM code for puerperal osteomalacia is M83.0 (sometimes written as M830). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is M83.0 (Adult osteomalacia) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report puerperal osteomalacia on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does M83.0 group to?

When puerperal osteomalacia is the principal diagnosis on an inpatient stay, it groups to MS-DRG 554, 553, with relative weights from 0.8328 to 1.2492 depending on complications. Higher weights mean higher Medicare reimbursement.

Who can M83.0 be reported for?

The Medicare Code Editor checks puerperal osteomalacia against patient demographics: this code is intended for maternity cases (age 9 through 64). Claims outside these limits are flagged as inconsistent.

Can M83.0 be reported with E55.0?

Not as a rule. The Excludes1 note at M83, which applies to M83.0, lists "infantile and juvenile osteomalacia (E55.0)". 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).

Does M83.0 risk-adjust for Medicare Advantage payment?

Not for Medicare Advantage: M83.0 maps to no category in the CMS-HCC V28 model. It still risk-adjusts in the RxHCC Part D (V08) category 87 (Osteoporosis, Vertebral and Pathological Fractures).
