ICD-10 Code for Gout, Unspecified (M10.9)
Most Commonly Used Code: M10.9 is frequently used when a provider documents gout but does not specify the joint(s) involved, cause, or laterality.
Why ICD-10 Codes for Gout Are Important
Gout is a common form of inflammatory arthritis caused by the deposition of urate crystals in joints. The ICD-10 code M10.9 is used by clinicians, hospitals, and medical billing teams when the specific details (joint location, primary vs secondary gout) are not documented.
Accurate diagnosis reporting
Helps providers and healthcare facilities record gout in a clear, consistent way even when details are lacking.
Medical billing & insurance claims
Insurance payers require correct ICD-10 codes for reimbursement. M10.9 ensures claims are processed when gout is documented without further specification.
Research & public health tracking
Proper usage of M10.9 supports population-level studies of gout prevalence, treatment patterns, and risk factors.
