Skeletal fluorosis, unspecified hand

This code signifies a chronic bone disease resulting from excessive fluoride intake, specifically affecting the bones of an unspecified hand. Skeletal fluorosis leads to increased bone density, calcification of ligaments, and potential joint pain and stiffness. The unspecified nature indicates the specific hand (right or left) is not documented.

This code is appropriate when documentation confirms a diagnosis of skeletal fluorosis and the affected site is identified as a hand, but the laterality (right or left) is not specified. Supporting documentation would include imaging reports showing characteristic bone changes (e.g., osteosclerosis, periosteal new bone formation) and a history consistent with chronic fluoride exposure.

• Always attempt to clarify laterality (right or left hand) from the provider to use a more specific code if available.
• Do not use this code if the fluorosis is dental (K00.3) or if the specific hand is known.
• Consider co-reporting codes for associated symptoms like arthralgia (M25.54-) or joint stiffness (M25.64-) if documented.
