- Billable — Valid for Submission
- Chronic Condition
G60.8 is a billable ICD-10-CM diagnosis code for other hereditary and idiopathic neuropathies. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 73 through 74. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Polyneuropathies.
G60.8 does not risk-adjust for Medicare Advantage under the CMS-HCC V28 model. It still risk-adjusts in the ESRD (V21) category 75 for payment year 2027.

Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to G60.8: its own notes plus those printed at block G60-G65 and Chapter 6. A note printed at a category, block or chapter applies to every code under it.
Applicable To
Conditions this code is used for: synonyms of the title or, for "other specified" codes, the conditions assigned to it. The list is not exhaustive.
- Dominantly inherited sensory neuropathy
- Morvan's disease
- Nelaton's syndrome
- Recessively inherited sensory neuropathy
Excludes1
Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.
Excludes2
Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.
- certain conditions originating in the perinatal period (P04-P96)
- certain infectious and parasitic diseases (A00-B99)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
- congenital malformations, deformations, and chromosomal abnormalities (Q00-Q99)
- endocrine, nutritional and metabolic diseases (E00-E88)
- injury, poisoning and certain other consequences of external causes (S00-T88)
- neoplasms (C00-D49)
- symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)

Peripheral Nerve Disorders
Nerves are like wires that carry messages back and forth between your brain and your body. Your peripheral nerves branch off from your brain and spinal cord and connect to all parts of your body, including your muscles and organs.

Questions About G60.8Overview
What is the ICD-10 code for other hereditary and idiopathic neuropathies?
The ICD-10-CM code for other hereditary and idiopathic neuropathies is G60.8 (sometimes written as G608). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is G60.8 (Hereditary and idiopathic neuropathy) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report other hereditary and idiopathic neuropathies on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does G60.8 group to?
When other hereditary and idiopathic neuropathies 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 G60.8 be reported with M79.2?
Not as a rule. The Excludes1 note at block G60-G65, which applies to G60.8, 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 G60.8?
Under the General Equivalence Mappings, other hereditary and idiopathic neuropathies converts to ICD-9-CM 356.8 (idio periph neurpthy NEC). The mapping is approximate, so confirm the match fits the documentation.
Does G60.8 risk-adjust for Medicare Advantage payment?
Not for Medicare Advantage: G60.8 maps to no category in the CMS-HCC V28 model. It still risk-adjusts in the ESRD (V21) category 75 (Polyneuropathy).
