Traum subdr hem with LOC status unknown, sequela

This code signifies a chronic or late effect of a traumatic subdural hemorrhage where the initial loss of consciousness duration is not documented. It indicates that the patient is experiencing ongoing neurological or physical impairments directly attributable to the past subdural bleed. The "sequela" aspect implies that the acute phase of the injury has passed, and the patient is now dealing with residual complications.

Apply this code when a patient presents with long-term neurological deficits (e.g., cognitive impairment, motor weakness, seizures) that are documented as a direct consequence of a previously sustained traumatic subdural hemorrhage. This code is appropriate when the medical record explicitly states that the initial loss of consciousness status was unknown or not recorded at the time of the acute injury. Documentation should clearly link the current symptoms to the past traumatic subdural hemorrhage.

• Always sequence this code after the code(s) for the specific sequelae being treated (e.g., G93.40 for encephalopathy, R29.810 for falls).
• Ensure documentation clearly states "sequela" or "late effect" and explicitly links the current condition to the past traumatic subdural hemorrhage.
• Do not use this code for acute or subacute traumatic subdural hemorrhages; those require codes from the S06.5X category without the "S" seventh character.
