What This Code Means

Lupus-like symptoms and inflammation caused by taking certain medications, which typically resolve when the drug is stopped.

Coding Tips

•Always document the specific medication causing the drug-induced lupus in the medical record
•Link this code with the appropriate drug adverse effect code (T36-T50 series) to show causation

Clinical Significance

Drug-induced lupus is typically reversible when the offending medication is discontinued, but requires careful monitoring and documentation of the causative agent. This diagnosis is crucial for medication management and avoiding future drug exposures that could trigger recurrence.

Documentation Requirements

✓Clear documentation of systemic lupus erythematosus symptoms
✓Identification of the specific drug causing the lupus-like syndrome
✓Timeline showing relationship between drug exposure and symptom onset
✓Laboratory evidence (ANA, anti-histone antibodies, complement levels)
✓Documentation of improvement after drug discontinuation
✓Exclusion of idiopathic SLE
✓Current treatment plan and monitoring
✓Patient education about avoiding the causative medication

Use Additional Code

code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5)

Commonly Confused Codes

M32.9 — Use for idiopathic SLE, not drug-induced lupus M32.10-M32.19 — Use for SLE with specific organ involvement, not drug-induced L10.4 — Use for drug-induced pemphigoid, not lupus T88.7 — Use for unspecified adverse drug effect, not when lupus is specifically documented
