Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to G57.83: its own notes plus those printed at G57, block G50-G59, and Chapter 6. A note printed at a category, block or chapter applies to every code under it.

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

From G57 Mononeuropathies of lower limb applies to 40 codes

Questions About G57.83Overview

What is the ICD-10 code for other specified mononeuropathies of bilateral lower limbs?

The ICD-10-CM code for other specified mononeuropathies of bilateral lower limbs is G57.83 (sometimes written as G5783). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is G57.83 (Other specified mononeuropathies of lower limb) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report other specified mononeuropathies of bilateral lower limbs on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does G57.83 group to?

When other specified mononeuropathies of bilateral lower limbs is the principal diagnosis on an inpatient stay, it groups to MS-DRG 74, 73, with relative weights from 1.0172 to 1.5773 depending on complications. Higher weights mean higher Medicare reimbursement.

Can G57.83 be reported with M79.2?

Not as a rule. The Excludes1 note at block G50-G59, which applies to G57.83, lists "neuralgia NOS (M79.2)". 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 G57.83?

Under the General Equivalence Mappings, other specified mononeuropathies of bilateral lower limbs converts to ICD-9-CM 355.79 (oth mononeur lower limb). The mapping is approximate, so confirm the match fits the documentation.
