What is the M79.602 Diagnosis Code?
The ICD-10 M79.602 diagnosis code is used to document left arm pain under the musculoskeletal disorders category. It's specifically used for soft tissue pain in the left arm that lacks a clear cause. The M79.602 code includes pain in the shoulder, upper arm, forearm, or hand, but it’s primarily used when the pain cannot be attributed to a specific joint or structure.
M79.602 helps healthcare providers accurately document the patient's condition. It’s essential to differentiate between pain in the left arm and conditions that are more localized, such as shoulder pain (M25.511) or elbow pain (M25.521). Using the right code ensures that your claims are accepted, and your practice is reimbursed fairly for the services rendered.
Clinical Scenarios for Using M79.602
ICD-10 code M79.602 is used in cases where the pain is generalized or non-specific, such as:
- Diffuse myalgia (muscle pain) in the left arm
- Non-specific soft tissue pain in the upper extremity
- Generalized discomfort that does not have a clear structural cause
- Pain extending across multiple anatomical regions in the arm
If a patient experiences persistent pain in the left arm, a thorough assessment should be performed. It's important to document the pain’s location, duration, severity, and factors that exacerbate or relieve the discomfort. This detailed documentation will support the M79.602 code and ensure that your practice gets the correct reimbursement.
Distinguishing M79.602 from Related Codes
It’s crucial to choose the correct code when billing for left arm pain. The ICD-10 system offers several codes that may seem similar but cover different conditions:
ICD-10 Code | Description | When to Use | When Not to Use |
---|---|---|---|
M79.602 | Pain in left arm | Generalized pain in the left arm | For localized pain or specific injuries |
M25.511 | Pain in right shoulder | Pain in the right shoulder | If pain is in the left shoulder |
M25.521 | Pain in right elbow | Pain in the right elbow | If pain is in the left elbow |
G56.01 | Carpal tunnel syndrome, right upper limb | Nerve compression symptoms in the right wrist | For pain unrelated to carpal tunnel syndrome |

Essential Documentation for M79.602 Claims
To ensure proper reimbursement for M79.602 claims, comprehensive documentation is essential. Payers require clear and specific records to justify the diagnosis and treatment plan. Here are key documentation elements for left arm pain:
- Pain characteristics: Describe the location, intensity (using a 0-10 scale), and duration of pain
- Functional impact: Note how the pain limits the patient's activities (e.g., inability to lift, difficulty using a keyboard)
- Physical examination findings: Include range of motion (ROM), strength, and any tenderness in the arm
- Previous treatments: Record treatments attempted (e.g., medication, physical therapy) and their effectiveness
