@moduledoc """
Room Coverage (RMC) -- HL7v2 composite data type.
Specifies room coverage type, amount, and percentage for insurance.
4 components:
1. Room Type (IS) -- Table 0145: e.g., "PR" (private), "SP" (semi-private)
2. Amount Type (IS) -- Table 0146: e.g., "LM" (limit), "PC" (percentage), "UP" (unlimited)
3. Coverage Amount (NM) -- the numeric coverage value
4. Money or Percentage (MOP) -- v2.5.1 added; rarely populated, treated as ST
