K22.70 - Barrett's esophagus without dysplasia

Clinical Definition

Acute myocardial infarction, commonly known as a heart attack, occurs when blood flow to a portion of the heart muscle is blocked, causing tissue damage or death. The unspecified type indicates the documentation doesn't specify STEMI, NSTEMI, or other specific types.

Documentation Requirements

• Acuity:

  • Must specify "acute" (first 4 weeks)

  • Document if subsequent (within 4 weeks of initial MI)

  • State if old/healed (after 4 weeks)

• Location:

  • Document specific wall involvement (anterior, inferior, lateral, etc.)

  • Note if multiple sites are involved

• Type:

  • Specify STEMI vs. NSTEMI when known

  • Document if transmural or subendocardial

  • Note presence/absence of ST elevation

• Timing:

  • Document exact onset time/date

  • Specify which episode (initial, subsequent, sequela)

Common Synonyms

• Heart attack

• Coronary

• Cardiac arrest (note: not the same thing)

• "Widowmaker"

• "The Big One"

Coding Conflicts

Excludes1:

• Old myocardial infarction (I25.2)

• Post-myocardial infarction syndrome (I24.1)

• Subsequent myocardial infarction (I22)

Scribing.io Automation

Our AI scribe automatically identifies:

• Temporal markers indicating acuity

• Anatomical references to heart walls

• ECG findings suggestive of MI

• Keywords indicating type (STEMI/NSTEMI)

• Treatment modalities suggesting MI care

The system flags when key documentation elements are missing and prompts for specificity when "unspecified" codes might be used.
