CM states the fact of closure without attributing it to the consumer or the grantor. It is the neutral option.
Because it is neutral, CM is the wrong choice whenever a specific code fits: AP for a consumer-requested closure, CH or CI for a credit line, CJ for a paid collection, CL for a paid lease.
CM does NOT mean the balance is zero. Closed and paid are different facts, carried by different fields.
CM does NOT explain why the account closed. If the reason matters on the report, use the code that carries it.
CM is terminal. A closed account does not need the comment re-explained every cycle once the tradeline is finished.

1A lender closes a small deposit-related credit account at maturity where no more specific comment fits.
2A furnisher closes an account following an internal product retirement that was neither a risk closure nor a consumer request.
3An account is closed as part of a relationship ending by mutual agreement.
4A furnisher closes a legacy account carried over from an acquisition once its balance is resolved.

Populate Date Closed in the same record. A closure comment without a Date Closed is a contradiction.
Prefer a specific closure comment when one applies. CM is the fallback, not the default.
Do not use CM to avoid stating that the grantor closed the account; if CH is the fact, report CH.
Report Current Balance honestly. A closed account can still carry a balance being paid down.
Stop reporting the comment once the tradeline is finished and no longer being updated.

A file can be structurally valid and still be wrong. These are the cross-field conditions Special Comment Code CM has to satisfy.

Requires Date Closed to be populated.
Account Status 13 (paid and closed with a zero balance) pairs with CM when the balance was settled; otherwise the status must show the account is closed but not paid.
Current Balance greater than zero alongside a paid status is a contradiction the bureaus will edit.
Credit Limit should not imply available credit on a closed revolving account.
Date Opened stays unchanged. Closing an account never re-ages it.
