M10.01 Idiopathic gout, shoulder

ICD-10-CM Code M10.01: Idiopathic gout, shoulder

ICD-10-CM code M10.01 identifies idiopathic gout located in the shoulder region. Gout is a metabolic disease associated with the deposition of uric acid crystals in tissue, which can lead to inflammatory arthritis and tissue damage. While gout frequently affects joints in the feet and ankles, it can also affect the shoulder. 1 3 4

Plain-language overview

Gout is a metabolic disease associated with the deposition of monosodium urate crystals, leading to inflammatory arthritis and eventual tissue damage. The condition involves uric acid crystals being deposited in tissue and causing discomfort. 1 3

What this code represents

Code M10.01 represents idiopathic gout in the shoulder region, an area that includes the collarbone, shoulder blade, and humerus, along with the shoulder joint and a second joint connecting the shoulder blade to the collarbone. 3 4

Clinical context

Gouty arthritis affects the joints of the feet, ankles, knees, fingers, wrist, and shoulder. Gout is also identified as an associated risk factor in patients with frozen shoulder, a condition that causes a persistent inflammatory response leading to fibrosis in the shoulder. 1 2

Coding details

Code M10.01 is listed alongside other idiopathic gout codes that specify different anatomical sites, such as M10.00 for an unspecified site and M10.02 for the elbow. The source listing also includes codes for other gout categories, such as lead-induced gout. 4

Documentation considerations

The provided sources establish the code M10.01 and its associated label, idiopathic gout of the shoulder, but they do not explicitly state the clinical documentation rules for differentiating idiopathic gout from other types or recording specific anatomical sites to support code selection. 3 4

What the sources add

The clinical literature from PMC describes gout as a metabolic disease with crystal deposition causing inflammatory arthritis, whereas the coding source from gesund.bund.de provides the specific anatomical context of the shoulder bones and joints for the M10.01 code. 1 3

Coverage and utilization context

The provided coding and clinical sources establish the diagnostic label and medical context for idiopathic gout of the shoulder, but they do not contain payer-specific coverage policies or utilization management rules for this condition. 1 3 4
