ICD-10-CM Coding for Confirmed Adult Physical Abuse in Inpatient Settings
For a patient with confirmed adult physical abuse now admitted to your facility (regardless of where they were previously seen), use code T74.11XA (Adult physical abuse, confirmed, initial encounter) or T74.11XD (Adult physical abuse, confirmed, subsequent encounter) depending on whether this is the first time you are documenting this abuse episode.
Coding Algorithm for Your Scenario
Step 1: Determine Encounter Type
- Initial encounter (T74.11XA): Use this if this is the first time any provider is documenting this specific abuse episode, even if the patient was previously hospitalized elsewhere for unrelated reasons
- Subsequent encounter (T74.11XD): Use this if the abuse was already documented/coded during a prior encounter for this same abuse episode (including at the other facility if you have documentation confirming this)
Step 2: Code Selection Based on Certainty Level
The research evidence shows that ICD-10 codes for abuse have varying positive predictive values 1:
- T74.12 series ("Adult and child abuse, neglect, and other maltreatment, confirmed"): Highest positive predictive value (0.89) - use when abuse is definitively established
- T76 series ("Adult and child abuse, neglect, and other maltreatment, suspected"): Use only when abuse is suspected but not yet confirmed
- Z04.72 ("Encounter for examination and observation following alleged abuse"): Lowest positive predictive value (0.24) - avoid using this for confirmed cases 1
Step 3: Add Appropriate 7th Character Extension
- A = Initial encounter (first documentation of this abuse episode)
- D = Subsequent encounter (follow-up care for previously documented abuse)
- S = Sequela (late effects of abuse, used rarely)
Critical Coding Pitfalls to Avoid
Do not use "suspected" codes (T76.11) when abuse is confirmed - this is the most common coding error and significantly undermines documentation quality and tracking capabilities 1, 2.
Do not assume "initial encounter" means first time seeing the patient - it refers to the first time documenting this specific abuse episode, not the patient's first visit to your facility overall.
Be aware of mandatory reporting requirements - all 50 states mandate reporting of suspected elder abuse, though requirements vary by jurisdiction 3. Coding confirmed abuse triggers legal reporting obligations regardless of where the patient was previously seen.
Additional Documentation Considerations
When coding confirmed adult physical abuse, your documentation should include:
- Specific physical findings and injuries (use additional injury codes as needed)
- Perpetrator relationship if known (use additional Y07 codes for perpetrator relationship)
- Place of occurrence if relevant (use Y92 codes)
The evidence shows that proper ICD-10 coding is essential for tracking abuse cases at institutional and national levels, though coding errors remain common and likely underestimate true injury burden 2.
