Neuropathic pain, a complex condition resulting from nerve damage, requires precise diagnosis and coding for effective treatment and insurance purposes. The International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) provides a standardized system for this, and while there isn’t a single, dedicated “Diagnosis Code For Neuropathic Pain,” understanding codes like M79.2 is crucial. This article will delve into the specifics of ICD-10-CM code M79.2, exploring its relevance to neuropathic pain and its application in medical coding.
Decoding ICD-10-CM Code M79.2: Neuralgia and Neuritis, Unspecified
ICD-10-CM code M79.2 is categorized as “Neuralgia and neuritis, unspecified.” This code is designated as billable and specific, meaning it is valid for medical claims and provides a detailed level of diagnostic information, although “unspecified” indicates a lack of further detail about the exact location or cause of the neuralgia or neuritis. The 2025 edition of ICD-10-CM M79.2, effective from October 1, 2024, remains consistent with previous years, indicating its established use in the medical coding system within the United States. It’s important to note that while this is the American ICD-10-CM version, international versions of ICD-10 M79.2 might have variations.

Type 1 Excludes: What M79.2 Does Not Cover
In ICD-10-CM, “Type 1 Excludes” notes are critical for accurate coding. A type 1 excludes note associated with M79.2 signifies conditions that should never be coded together with M79.2. It acts as a pure exclusion, meaning “not coded here.” This typically applies when two conditions are mutually exclusive, such as congenital versus acquired forms of the same condition. For M79.2, it implies that if a more specific diagnosis exists for the neuralgia or neuritis, then M79.2 should not be used.
Annotation Back-References: Contextualizing M79.2
“Annotation back-references” in ICD-10-CM codes provide crucial context and links to related coding guidelines. For M79.2, these back-references point to codes that contain various annotations applicable to M79.2. These annotations can include:
- Applicable To: Conditions where M79.2 might be applicable.
- Code Also: Codes that should be used in conjunction with M79.2 to provide a more complete clinical picture.
- Code First: Underlying condition codes that should be coded before M79.2.
- Excludes1 & Excludes2: Further clarification on what conditions are excluded from or not typically associated with M79.2.
- Includes: Conditions that are included under the M79.2 code.
- Note: Additional guidance or clarification notes related to M79.2.
- Use Additional: Instructions to use additional codes to specify certain aspects of the condition.
These annotations ensure coders consider all relevant information for accurate and comprehensive coding.
Synonyms and Related Terms for M79.2
Understanding the synonyms for M79.2 helps clarify its scope. Approximate synonyms for M79.2 include:
- Bilateral ulnar neuritis
- Neuralgia
- Neuralgia (nerve pain)
- Neuralgia of left arm, right arm, upper limb, leg
- Neuritis
- Neuritis (nerve inflammation)
- Neuropathic (nerve) pain
- Neuropathic pain
Notably, “neuropathic pain” and “neuropathic (nerve) pain” are listed as synonyms, directly linking M79.2 to the concept of neuropathic pain, even though the code itself is “unspecified.” This is where the nuance of medical coding becomes apparent. While M79.2 isn’t the most specific code for neuropathic pain, it can be used when the documentation doesn’t specify the exact type or location of neuralgia or neuritis causing neuropathic pain.
Diagnostic Related Groups (DRG) and Code History
ICD-10-CM M79.2 falls within specific Diagnostic Related Groups (MS-DRG v42.0), which are used for hospital reimbursement and statistical analysis. The code’s history shows it was introduced in 2016 and has remained unchanged through the 2025 edition. This stability indicates its continued relevance and acceptance within the ICD-10-CM coding framework.
M79.2 in the Context of Neuropathic Pain Diagnosis
While more specific ICD-10-CM codes may exist for neuropathic pain depending on the underlying cause or location, M79.2 serves as a valuable code when the specifics of the neuralgia or neuritis are not fully documented. In cases where a patient presents with symptoms indicative of neuropathic pain due to neuralgia or neuritis, but further diagnostic investigation is needed to pinpoint the exact etiology or anatomical site, M79.2 can be appropriately used. It signals nerve-related pain (neuralgia/neuritis) without specifying the underlying cause, aligning with situations where a definitive diagnosis of neuropathic pain is established, but the precise nature of the nerve involvement remains “unspecified” at the time of coding.
