About the 0LN Code Range

The ICD-10-PCS root operation Release involves freeing a body part from an abnormal physical constraint by cutting or otherwise disrupting restrictive tissue. In the Medical and Surgical section, it specifically applies to tendons throughout various anatomical regions.

This root operation is used to alleviate tension or deformity caused by constrictive tissues impacting a tendon’s normal function. The included codes demonstrate the versatility of the Release operation in different locations such as the head and neck (0LN00ZZ, open approach), shoulder tendons on the right or left side (0LN10ZZ, open approach; 0LN23ZZ, percutaneous approach), and tendons of the upper and lower arms, trunk, hip, leg, knee, ankle, and foot. Approaches range from open to percutaneous, percutaneous endoscopic, and external approaches, allowing tailored procedural documentation. Accurately coding the 0LN - Release operation is essential to capture the precise site and method of tendon release interventions in medical records.
