Every version by contractor
Open a version for its full policy text, contracts, codes and related NCDs. Covered codes are the count of ICD-10-CM codes in the version's billing and coding article; a dash means the export attaches no coded article.

Lineage
The Medicare Coverage Database records the source policy a determination was derived from: L33624 from L25507; L33975 from L28950; L34183 from L31890; L34570 from L31600. A shared source explains why the opening paragraphs read alike; the revision dates and the diagnosis counts above show where the versions have since parted.
How to use the comparison
Start from the state where the service is furnished and open that contractor's version; its billing and coding article carries the diagnosis codes the claims system will test. For a group that bills in several jurisdictions, the version with the smallest covered list is the safe common denominator for pre-service review, and the version with the largest list shows what documentation can support an appeal elsewhere. The L33624 version is the one most searched for this title; the LCD lookup guide explains how jurisdictions are assigned, and the LCD hub lists every topic that more than one contractor has written.
Frequently asked questions
Why are there 4 LCDs called "Psychiatric Inpatient Hospitalization"?
Each Medicare Administrative Contractor writes its own Local Coverage Determination for its jurisdiction. 4 contractors publish a policy with this title covering 25 states; they often start from one contractor's text and then revise separately, so dates, criteria and diagnosis lists differ by jurisdiction.
Which "Psychiatric Inpatient Hospitalization" LCD applies to my claim?
The one written by the contractor that processes the claim: the A/B MAC for the state where the service is furnished, or the DME MAC region for equipment. The table lists each policy's states; open the policy for that jurisdiction and its billing and coding article.
How different are the diagnosis lists?
Among the 4 versions with a billing and coding article, the covered ICD-10-CM list ranges from 1 to 422 codes. A diagnosis accepted under one contractor can deny under another, which is the most common cause of coverage denials for multi-state groups.
When were these policies last revised?
Revision effective dates run from 2021-01-01 to 2026-04-02. A claim is judged against the version in force on the date of service.
