Corros 3rd deg of shldr/up lmb, ex wrs/hnd, unsp site, sqla

This code signifies a third-degree chemical burn (corrosion) affecting the shoulder or any part of the upper limb, excluding the wrist and hand, where the specific location on the limb is not documented. The "S" at the end indicates that this code is used for sequelae, meaning complications or conditions that arise as a direct result of the original corrosion, even after the acute phase has passed.

Use this code when documenting long-term effects or complications stemming from a third-degree chemical burn to the shoulder or upper limb (excluding wrist/hand) where the exact site was not specified. This could include chronic pain, scarring, contractures, or functional limitations directly attributable to the past corrosive injury. It is appropriate when the initial acute injury has healed, but its lasting impact is being treated or evaluated.

• Always ensure the documentation clearly links the current condition to a past third-degree chemical burn of the specified body region.
• Do not use this code for acute third-degree chemical burns; instead, use the appropriate acute T22.7- code with the initial encounter or subsequent encounter seventh character.
• Code any specific sequelae (e.g., contracture, scar) in addition to this code, if applicable, to provide a complete clinical picture.
