What is ICD-10 M25.562 (Left Knee Pain) and When to Use It

Knee pain is one of the most common musculoskeletal complaints healthcare providers encounter, especially in holistic and integrative practices where patients seek long-term relief and whole-body wellness. For accurate medical billing and streamlined revenue cycle management, documenting the correct ICD-10 code is a must. One code that frequently comes up is ICD-10 M25.562 Left Knee Pain.

This guide explains what this code means, when to use it, and how proper documentation helps providers avoid claim denials and improve reimbursement.


Understanding ICD-10 M25.562

The ICD-10 code M25.562 is used to represent pain in the left knee. It falls under the category of ICD-10 musculoskeletal disorders, specifically within the subset of “pain in joint” coding.

Using the correct ICD-10 code ensures that claims accurately reflect a patient’s condition. For holistic and integrative practices, this accuracy not only supports proper reimbursement but also helps align treatment with patient-centered care plans.


When to Use ICD-10 M25.562

This diagnosis code should be used when documenting left knee joint pain without specifying an underlying cause. Common clinical scenarios include:

  • Acute left knee pain following sudden strain, sprain, or minor injury.

  • Chronic left knee pain linked to ongoing musculoskeletal issues, such as arthritis or overuse.

  • Unspecified left knee musculoskeletal disorder where pain is the primary symptom.

If the pain is due to a more specific condition, such as a meniscus tear or ligament injury, a more precise knee injury ICD-10 code should be used instead. For billing accuracy, always code to the highest level of specificity.


Why Correct Coding Matters

Accurate coding for left knee musculoskeletal disorders affects both patient care and practice revenue. Misuse of codes can result in:

  • Claim denials due to insufficient or incorrect documentation.

  • Delayed reimbursement, which can disrupt practice cash flow.

  • Compliance issues if coding does not align with payer requirements.

On the other hand, using the correct knee pain diagnosis code ensures that your documentation reflects the medical necessity of the treatment provided.


While M25.562 is specific to left knee pain, here are related codes that may apply:

  • M25.561 – Pain in right knee

  • M25.569 – Pain in unspecified knee

  • M79.662 – Pain in left lower leg (use if pain extends below the knee)

  • S83 series – For sprains and ligament injuries

  • M17 series – For knee osteoarthritis

Providers should carefully differentiate between acute left knee pain ICD-10 codes, chronic conditions, and injury-related coding to avoid misclassification.


Documentation Tips for Holistic and Integrative Practices

When documenting knee joint pain coding, consider including:

  • Onset and duration – Acute vs. chronic left knee pain.

  • Pain location – Left knee, with notes if radiating to lower leg.

  • Contributing factors – Overuse, trauma, or musculoskeletal imbalance.

  • Impact on function – Limited mobility, difficulty walking, or activity restrictions.

These details not only support the ICD-10 code selection but also create a stronger clinical picture for insurers.


Final Thoughts

For healthcare providers, especially in holistic and integrative settings, coding accuracy is a cornerstone of financial health. Using ICD-10 M25.562 for left knee pain appropriately allows for smoother billing, fewer claim denials, and more focus on patient care.
