ICD-10 Code M10.9 is a billable code used by healthcare providers to diagnose and process reimbursement claims for Gout, Unspecified. This condition is a common and painful form of arthritis characterized by swollen, red, hot, and stiff joints. It results from the accumulation of uric acid in the blood, leading to the formation of crystals in the joints and surrounding tissues.
Transition from ICD-9 Code 274.9
The corresponding ICD-9 code for Gout, Unspecified is 274.9. With the transition to ICD-10, healthcare providers have access to more detailed and specific codes, allowing for better tracking, diagnosis, and treatment planning.

Expanded Benefits of ICD-10 Codes
The ICD-10 system, developed by the World Health Organization (WHO), is the 10th revision of the International Statistical Classification of Diseases and Related Health Problems. It offers more precise classifications for medical conditions compared to its predecessor, ICD-9. Here are some notable advantages:
- Enhanced Specificity: The ICD-10-CM (Clinical Modification) contains over 70,000 codes, enabling more detailed tracking of diagnoses.
- Compliance with HIPAA: ICD-10 is mandated under the Health Insurance Portability and Accountability Act (HIPAA) for use by physicians and other healthcare providers.
- Improved Data Analysis: With expanded code sets, healthcare organizations can perform better analysis of patient outcomes and resource utilization.

Frequently Asked Questions (FAQs)
ICD-10 Code M10.9 is used to describe “Gout, unspecified” in medical records and billing. This code applies when a patient is diagnosed with gout, but the specific type (like gouty arthritis or tophi) hasn’t been clearly defined yet.
Doctors often use this code during initial diagnosis when further lab results or clinical evaluations are pending.
This code is typically used when a patient has clear symptoms of gout, such as sudden joint pain, redness, or swelling often in the big toe but the provider hasn’t yet classified it into a more specific category.
It’s a general placeholder that still allows accurate documentation and reimbursement while further testing is ongoing.
Yes, absolutely. ICD-10 M10.9 is a billable diagnosis code and is commonly accepted by insurance companies, including Medicare and Medicaid.
However, when more clinical information becomes available, providers are encouraged to use a more specific gout code to ensure better claim clarity and avoid denials.
Not exactly. While M10.9 refers to unspecified gout, it does not include specific forms like:
- M10.0 – Idiopathic gout
- M10.2 – Drug-induced gout
- M10.3 – Gout due to renal impairment
M10.4 – Secondary gout
If a provider knows the exact cause or type of gout, it’s better to use one of those more detailed ICD-10 codes.
Doctors may assign M10.9 when a patient reports:
Sudden joint pain (commonly in the toe, ankle, or knee)
Swelling, warmth, or redness in joints
Limited joint mobility
These symptoms strongly point toward gout, and M10.9 is the starting point for diagnosis and treatment planning.
To avoid errors, make sure:
- You’re not overlooking a more specific gout type.
- Documentation supports the diagnosis clearly.
- You’re updating the code if the condition is later reclassified.
Coding M10.9 is totally valid, but updating it to a more specific ICD-10 code helps improve billing accuracy and patient care tracking in the long run.
