Description
Subtract a supplied reversal from an original pharmacy claim.
Pharmacy records distinguish prescribed wording, recorded supply, package counts, consultation timing and product identifiers. A partial-fill balance can reveal a recorded overfill without determining lawful supply, and a lot-code comparison does not retrieve a recall. Preserving a dose string does not interpret or recommend the dose.
Subtract a supplied reversal from an original pharmacy claim.
When to use this tool
Use Pharmacy Claim Reversal Amount when you already have originalClaimAmount, reversalAmount and need to subtract a supplied reversal from an original pharmacy claim.
How to use the tool and how it works
- Enter originalClaimAmount, reversalAmount. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read remainingClaimAmount. Use the output convention below.
Require both amounts>=0; return original-reversal without clamping.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| originalClaimAmount | Original Claim Amount | Required. Finite number; minimum 0. |
| reversalAmount | Reversal Amount | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| remainingClaimAmount | Remaining Claim Amount | Required. Finite number. |

}Limitations and assumptions
- A larger reversal gives negative balance. No actual claim, entitlement, reimbursement, account or reversal authority is verified.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Review the original prescription, dispensing, consultation and product records within the appropriate professional workflow. Use verified clinical and regulatory information for supply or care decisions; local balances and labels do not establish suitability, authenticity or authorization.
