What This Code Means

Reiter's disease affecting the shoulder when the specific side (left or right) is not documented or is bilateral.

Coding Tips

• •Use code ending in '9' only when laterality cannot be determined from documentation
• •Query provider if documentation is unclear about which shoulder is affected to allow for more specific coding

Clinical Significance

Reiter's disease affecting the shoulder without specified laterality represents reactive arthritis that can impact shoulder function and upper extremity activities. Despite unspecified laterality, this condition still requires comprehensive management due to its chronic inflammatory nature and the functional importance of shoulder mobility.

Documentation Requirements

• ✓Clinical diagnosis of Reiter's disease or reactive arthritis
• ✓Shoulder involvement without laterality specification
• ✓History of preceding infection documented
• ✓Evidence of shoulder arthritis symptoms
• ✓Documentation of other Reiter's syndrome components when present
