W20.1XXD is a billable diagnosis code used to specify a medical diagnosis of struck by object due to collapse of building, subsequent encounter. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

W20.1XXD is a subsequent encounter code, includes a 7th character and should be used after the patient has completed active treatment for a condition like struck by object due to collapse of building. According to ICD-10-CM Guidelines a "subsequent encounter" occurs when the patient is receiving routine care for the condition during the healing or recovery phase of treatment. Subsequent diagnosis codes are appropriate during the recovery phase, no matter how many times the patient has seen the provider for this condition. If the provider needs to adjust the patient's care plan due to a setback or other complication, the encounter becomes active again.
